Cette thèse concerne la mise en forme et la structuration de polymères de coordination poreux (PCP, ou MOFs pour Metal-Organic Frameworks) au sein de membranes d'alumine macroporeuses (Øpores ˜ 200 nm), dont le rôle est double. Obtenus sous forme de cristaux, les MOFs sont fragiles. La membrane constitue d'une part une coque protectrice pour le polymère de coordination impliqué dans le matériau composite. D'autre part, elle fait office de matrice, permettant la fabrication de nanostructures unidimensionnelles (1D), obtenues après élimination sélective de la dite matrice. La fonctionnalisation préalable de la membrane, ainsi que les paramètres opératoires (concentration en réactifs, nombre de cycle de filtration, étape de lavage intermédiaire...) ont été largement étudiés, ce qui a permis d'élaborer avec succès plusieurs composites PCP/membrane. Ainsi, des composites incluant des PCP tels que HKUST-1, ZIF-8, et un matériau à transition de spin Fe(pz)[Ni(CN)4] ont été préparés. Pour le polymère de coordination ZIF-8, des nanofibres 1D ont été isolées avec succès après dissolution de la membrane. Tous les composites et les nano-objets résultants ont été amplement caractérisés en termes de morphologie (MEB, MET, AFM), de composition chimique (Raman, DRX, IR), et de propriétés (magnétiques ou d'adsorption/désorption de gaz). / This thesis aimed at the construction of porous coordination polymer (PCP, or MOFs Metal-Organic Frameworks for) within macroporous alumina membranes (Øpores ˜ 200 nm), whose role is twofold. Obtained as crystals, MOFs are fragile. The membrane firstly provides a protective shell for the coordination polymer embedded in the composite material. Moreover, the membrane acts as a matrix, enabling the elaboration of one-dimensional nanostructures (1D), obtained after selective elimination of the matrix. The functionalization of the membrane, and the experimental parameters (reagents concentration, number of cycles, intermediate washing-step...) have been widely studied. They allowed accessing various PCP/membrane composites. Composites involving HKUST-1, ZIF-8 and Fe(pz)[Ni(CN)4] spin transition MOFs have been prepared. For the coordination polymer ZIF-8, 1D nanofibers have been successfully isolated after dissolution of the membrane. These composites and the resulting nano-objects have been extensively characterized in terms of morphology (SEM, TEM, AFM), chemical composition (Raman, XRD, IR), and properties (magnetic or gas adsorption / desorption).

Transparent glasses embedded with ferroelectric/nonlinear optic crystallites have been in increasing demand as these exhibit promising physical properties. These could be fabricated in large sizes and shapes with high optical homogeneity accompanied by high degree of transparency over a wide range of wavelengths of light. Amongst a variety of glasses that are known, borate-based glasses are of particular interest owing to their greater transparency, good chemical and mechanical stability, low materials cost, and useful electrical and dielectric properties. Keeping the potential multifarious applications of transparent glass-microcrystal composites in view, BaO-0.5Na2O-4.5B2O3, BaO-0.5Li2O-4.5B2O3, SrO-0.5Li2O-4.5B2O3, 3BaO-3TiO2-B2O3 and Li2O-3B2O3 glasses and glass-microcrystal composites were fabricated. These glasses on controlled heat treatment at appropriate temperatures yielded BaNaB9O15, BaLiB9O15, SrLiB9O15, Ba3Ti3B2O12 and LiB3O5 crystalline phases, respectively. Further transparent surface crystallized BaO-0.5Na2O-4.5B2O3 glasses were fabricated using ultrasonic treatment and their thermal properties have been investigated in detail using differential scanning calorimetry. It is observed that these glasses were homogeneously crystallizing on the surfaces after Ultrasonic treatment which can be exploited for planner wave-guide applications. Glass forming ability, thermal stability, glass-transition behavior, crystallization kinetics and viscosity of these glasses were studied extensively using various methods and rationalized by invoking various models. The above glasses have been characterized for their dielectric and electrical relaxation properties (as these properties are related to their electro-optic and non-linear optical properties) over 30- 600oC temperature range and frequencies (100 Hz -10 MHz) that are normally of interest in the applications of these materials. Several interesting features such as high ionic conductivity, marginally low dielectric loss and high dielectric constant behavior along with low thermal coefficient of dielectric constant were observed in these glasses and were rationalized using various models. The combination of these dielectric characteristics suggests that these are potential candidates for electrical energy storage device applications.

Fiber-reinforced composites are currently being used in a wide range of lightweight constructions. Function integration, in particular, offers possibilities to develop new, innovative products for a variety of applications. The large amount of experimental testing required to investigate these novel material combinations often hinders their use in industrial applications. This paper presents an approach that allows the layout of adaptive, fiber-reinforced composites by the use of numerical simulation. In order to model the adaptive characteristics of this functional composite with textile-integrated shape memory alloys, a thermo-elastic simulation is considered by using the Finite Element method. For the numerical simulation, the parameters of the raw materials are identified and used to generate the model. The results of this simulation are validated through deflection measurements with a specimen consisting of a glass fiber fabric with structurally integrated shape memory alloys and an elastomeric matrix system. The achieved experimental and numerical results demonstrate the promising potential of adaptive, fiber-reinforced composites with large deformation capabilities.

[pt] Os profissionais da construção civil vêm se tornando mais conscientes sobre seu papel no agravamento dos problemas ambientais, levando estes à procura de métodos e materiais que apresentem menos impacto ambiental. O uso de fibras vegetais como reforço vem sendo feito ao longo dos anos de forma a melhorar as propriedades mecânicas de compósitos, sendo estas de caráter renovável e biodegradáveis. A presente pesquisa visa a caracterização de biocompósitos para fabricação de habitações sociais de baixo impacto ambiental através do processo de moldagem por compressão das placas de vedação de tecido de fibra de juta e matriz de poliuretano vegetal e de impressão 3D de perfis e ligações de PLA e fibra vegetal de juta, sisal e rami. Para as placas moldadas por compressão foi feito um estudo da influência da direção da fibra nas propriedades mecânicas, constatando, através de ensaio de flexão monotônica, que a direção principal da fibra (urdume do tecido) apresenta a melhor resistência e maior rigidez, alcançando 37,2 mais ou menos 0,9MPa e 10,4 mais ou menos 1,1GPa, respectivamente. Analisando os efeitos à longo prazo, foi estudado o efeito da radiação ultravioleta nas placas, onde foram feitos ensaios em corpos de prova nas direções 0 graus e 90 graus expostos a uma lâmpada ultravioleta de 365nm por 3 (três) meses. Além disso, com os resultados dos ensaios foi possível aplicar a regra das misturas de forma inversa na determinação das propriedades da fibra e da matriz. Para os compósitos impressos 3D foi analisada a influência do tipo de fibra na resistência à tração e rigidez do material. Pelo ensaio à tração foram constatados aumentos significativos na resistência com o uso de fibras de rami (61,8 por cento) e sisal (110,8 por cento), chegando à resistência de 45,5 mais ou menos 6,1MPa e 59,3 mais ou menos 4,1MPa, respectivamente. / [en] Civil construction professionals have become more aware of their role in aggravating environmental problems, leading them to search for methods and materials that have less environmental impact. Vegetable fibers have been used as reinforcement over the years to improve the mechanical properties of composites, which are renewable and biodegradable. This research aims at the characterization of biocomposites for social housing manufacture with low environmental impact through the sealing plates compression molded process of jute fiber fabric and vegetable polyurethane matrix and 3D printing of PLA profiles and connections of jute, sisal, and ramie vegetable fiber. For the compression molded plates, a study was made to determine the influence of fiber direction on mechanical properties, noting, through a monotonic bending test, that the main fiber direction (warp of the fabric) has the highest resistance and stiffness, with 37.2 plus or minus 0.9MPa and 10.4 plus or minus 1.1GPa, respectively. Analyzing long term effects, the plates were exposed to ultraviolet radiation. In these tests, the specimens were exposed to a 365nm ultraviolet lamp during three months before being submitted to directional resistance trials in 0 degrees and 90 degrees. Furthermore, with the test results, it was possible to apply the mixing rule inversely to determine the fiber and matrix properties. For 3D printed composites, the influence of fiber type on the material s tensile strength and stiffness was analyzed. The tensile test found significant increases in strength with the use of ramie (61.83 percent) and sisal (110.80 percent) fibers, reaching a strength of 45.5 plus or minus 6.1MPa and 59.3 plus or minus 4.1MPa, respectively.

[pt] A integridade de tubulações é um dos aspectos-chave para a operação segura e eficiente das estruturas offshore. Falhas em tubulações podem resultar em consequências econômicas e ambientais significativas, tornando a gestão da integridade de tubulações uma prioridade importante para a indústria. Uma das ferramentas mais eficazes para gerenciar tubulações em serviço é através de testes não destrutivos (NDT, na sigla em inglês). Neste estudo, inspeções de ultrassom e shearografia foram realizadas em tubulações metálicas com reparos compósitos ao longo de aproximadamente dois anos e seus resultados foram comparados. As amostras de tubos de aço com reparos compósitos foram submetidas a pouco mais de 13.500 horas de envelhecimento acelerado por névoa salina, em três diferentes temperaturas. As amostras foram removidas das câmaras de névoa salina em intervalos regulares e inspecionadas usando aparelhos de inspeção em campo. Os resultados mostraram que ambas as técnicas forneceram resultados consistentes entre cada inspeção, embora nem sempre fossem consistentes entre si. Mapas comparando as detecções e a precisão de cada técnica foram fornecidos. A viabilidade de cada técnica como ferramenta de campo para monitorar a integridade das tubulações também foi avaliada com resultados positivos. Além disso, uma metodologia de Arrhenius modificada foi proposta como um primeiro passo para prever a propagação de danos a longo prazo. / [en] Pipeline integrity is one of the key aspects for safe and efficient operation of offshore structures. Pipeline failures can result in significant economic and environmental consequences, making pipeline integrity management a top priority for the industry. One of the most effective tools for managing in-service pipelines is non-destructive testing (NDT). In this study, ultrasound and shearography inspections were performed on composite pipeline repairs over the course of approximately two years and their results were compared. The test samples evaluated were steel pipes with composite repairs and were submitted to just over 13,500 hours of salt-spray accelerated ageing, under three different temperatures. Test samples were removed from the salt-spray chambers at regular intervals and inspected by using field inspection apparatus. The results showed that both techniques provided consistent results between each inspection, although not always being consistent with each other. Maps comparing detections and accuracy of each technique were provided. The feasibility of each technique as a field tool for monitoring pipeline integrity was also evaluated with positive results. Furthermore, a modified Arrhenius methodology was proposed as a first step towards predicting long-term damage propagation.

[pt] Nos últimos anos, os materiais compósitos cimentícios vêm ganhando destaque na indústria da construção civil. Suas excelentes propriedades mecânicas e contribuição para o controle de propagação de fissuras são um atrativo para seu emprego como material de construção. No entanto, normas técnicas para projeto envolvendo estes materiais e estruturas ainda não são consagradas. Uma melhor compreensão do comportamento de materiais cimentícios com adição de fibras requer o estudo de suas fases e da interação entre elas. Análises em diferentes escalas possibilitam esta representação. Tensões e deformações, dano e iniciação de fissuras ocorrem na escala das heterogeneidades e ajudam a explicar e prever o comportamento do concreto em uma escala macroscópica. A modelagem e simulação do comportamento destes compósitos é complexa e desafiadora. Para tal, é necessário definir os principais mecanismos que descrevem o comportamento do material de modo a escolher a descrição matemática adequada. Esta dissertação propõe metodologias para a modelagem numérica multiescala de materiais compósitos cimentícios. A partir de informações obtidas na escala do material, busca-se compreender melhor o comportamento global do compósito. Para isto, serão desenvolvidos métodos numéricos e computacionais baseados no Método dos Elementos Finitos, em técnicas de Inteligência Artificial e nos conceitos da Mecânica do Dano Computacional. Na macroescala, um modelo contínuo equivalente é desenvolvido através de técnicas probabilísticas e de Inteligência Artificial. Na mesoescala, duas abordagens são propostas. A primeira inclui as fibras através de elementos de interface, e a segunda através de um novo elemento compósito fibra-matriz. Os modelos desenvolvidos permitem avaliar a evolução do dano, o processo de propagação de fissuras, e o comportamento global carga-deslocamento do compósito até a ruptura. Resultados experimentais da literatura suportam as conclusões do trabalho. / [en] In recent years, fiber reinforced cement-based materials have gained relevance in the civil engineering industry. Due to its excellent mechanical properties and contribution to crack propagation control, there is a great appeal to its usage as a construction material. However, technical standards for fiber reinforced concrete are still not established. A better understanding of the behavior of cement composite materials requires the representation of the material phases and their interfacial behavior. Stresses and strain distributions, damage evolution and fracture initiation develop at the observation scale of the heterogeneities and help to explain and predict the behavior of concrete at a macroscopic level. The numerical modeling of these composites emerge as challenging and complex problems. For this, it is necessary to define the main mechanisms that describe the material behavior in order to choose the proper mathematical formulation. This dissertation proposes methodologies for the numerical modeling of cement composite materials in a multiscale approach. From the information obtained at the material scale, this work aims at assessing the global behavior of the composite. Numerical and computational procedures will be developed based on the Finite Element Method, Artificial Intelligence techniques and concepts of Computational Damage Mechanics. At the macroscale, an equivalent continuum model is developed through probabilistic and Artificial Intelligence techniques. At the mesoscale, two approaches are proposed. The first includes the fibers through interface elements. The second adopts a new fiber-matrix composite element. With the models developed here, it is possible to evaluate damage evolution, fracture propagation patterns, load-displacement global behavior of the composite upto failure. Experimental results from the literature give support to the conclusions.

Dans ce manuscrit, un modèle complet pour la simulation de l'écoulement d'un fluide thermor éactif à travers un milieu poreux fortement compressible est présenté. Ce modèle est utilisé pour l'étude des procédés d'élaboration des matériaux composites par infusion à travers leur épaisseur (Liquid Resin Infusion-LRI et Resin Film Infusion-RFI ). Dans ces procédés, le mélange entre les renforts et la résine liquide est réalisé dans la direction transverse aux plans des préformes pendant la phase de mise en forme. Les coˆuts sont ainsi réduits et les problèmes de remplissage éliminés. Ces procédés sont néanmoins peu maîtrisés et les caractéristiques de la pièce finale difficilement prévisibles (principalement les épaisseurs et les porosités). La mise au point d'un modèle numérique constituerait un bon outil pour développer et finaliser de nouvelles solutions composites. D'un point de vue physique, l'infusion de la résine à travers l'épaisseur des préformes est une conséquence de la pression appliquée sur l'empilement résine/préforme. Dans cette analyse multi-physique deux types de problèmes sont rencontrés. Tout d'abord, on connait mal les conditions de couplage entre les zones liquides, gouvernées par les équations de Stokes, et les préformes imprégnées assimilées à des milieux poreux, gouvernées par une loi de Darcy et une loi de comportement mécanique non-linéaire. Par ailleurs, les interactions entre l'écoulement de la résine et la compression des préformes ne sont pas bien maîtrisées. Le modèle développé inclut donc une condition de Beaver-Joseph- Schaffman modifiée pour le couplage entre les zones de Darcy et de Stokes. Une formulation ALE pour l'écoulement de la résine dans un milieu poreux déformable subissant de fortes déformations est utilisée et couplée à une formulation Lagrangienne Réactualisée pour la partie solide. Ces deux mécanismes physiques sont couplés à des modèles thermo-chimiques pour traiter la réticulation de la résine sous l'action du cycle de température. Dans ce travail, un certain nombre d'outils numériques et de nouvelles formulations ont été développés en vue de simuler les procédés LRI et RFI. Chaque outil est étudié et validé analytiquement ou numériquement avant d'être intégré dans les modèles LRI /RFI. Des simulations numériques d'infusion sont ensuite présentées et commentées, puis une première comparaison avec des essais expérimentaux est proposée.

Le pli vocal humain possède des propriétés vibratoires exceptionnelles. Il est capable de supporter de grandes déformations, pour différent type de chargement, de manière répétée et réversible. Ces propriétés vibro-mécaniques particulières sont étroitement liées à sa microstructure: une structure multi-couches complexe fortement hétérogène composées de réseaux de fibres protéique. Cependant, il est encore aujourd'hui difficile de décrire précisément l'implication des spécificités microstructurales du pli dans son comportement biomécanique.Afin de préciser ce lien et d'aller vers une meilleure compréhension du comportement du tissu vocal, cette étude se propose d'aborder la problématique sous trois approches complémentaires, mélant caractérisation microstructurale, caractérisation mécanique et modélisation numérique. Dans un premier temps, la microstructure du pli a été étudiée emph{ex vivo} à l'aide d'une technique originale basée sur la tomographie à rayon X. L'usage de tomographie synchrotron par contraste de phase a permis de révéler la structure du tissu à différentes échelles. En particulier, des clichés 3D à forte résolution de la structure fibreuse des couches supérieures et musculaires du tissu ont pu être acquis. Ces clichés ont donné lieu à une analyse 3D quantitative de l'arrangement fibreux, permettant la détermination de descripteur d'orientation et de géométrie 3D des fibres.Dans un second temps, le comportement mécanique du tissu sous différentes conditions de chargement a été étudié. Un protocole a été proposé, afin de caractériser un même échantillon en traction, en compression et en cisaillement. Ces essais ont permis de compléter les connaissances existantes sur la biomécanique de pli, et constitue des données de références importantes pour la construction et la validation de modèle numérique.A partir des données acquises expérimentalement, un modèle micro mécanique a été développé. Ce modèle a la spécificité de prendre en compte l'arrangement 3D du tissu à travers une représentation idéalisée mais pertinente de sa microstructure fibreuse. Les réponses macroscopiques prédites pour différents chargements ont pu être comparées à l'expérience pour validation. A l'échelle microscopique, la cinématique des fibres au cours du chargement a pu être simulée. Les micromécanismes ayant lieu au cours de la déformation du réseau fibreux ont ainsi pu être identifiés, ouvrant de nouvelles perspectives dans la compréhension des propriétés multi-échelles du tissu. / The human vocal fold owns exceptional vibratory properties. It is capable of withstanding large deformations, for different types of loading, in a repeated and reversible manner. These particular vibro-mechanical properties are closely linked to its microstructure: a multi-layer complex structure composed of highly heterogeneous protein fibre networks. However, it is still difficult today to describe precisely the implication of the microstructural specificities of the fold in its biomechanical behaviour.In order to clarify this link and to move towards a better understanding of the behaviour of the vocal tissue, this study proposes to approach the problem under three complementary approaches, combining microstructural characterization, mechanical characterization and numerical modelling. First, the microstructure of the fold was studied emph{ex vivo} using an original technique based on X-ray tomography. The use of synchrotron tomography in phase retrieval mode has revealed the structure of the tissue at different scales. In particular, high-resolution 3D images of the fibrous structure of the upper and muscular layers of the tissue were acquired. These images gave rise to a quantitative 3D analysis of the fibrous arrangement, allowing the determination of descriptors of orientation and 3D geometry of the fibers.In a second step, the mechanical behaviour of the fabric under different loading conditions was studied. A protocol has been proposed to characterize the same sample in tension, compression and shear. These tests have complemented existing knowledge on fold biomechanics, and constitute important reference data for the construction and validation of digital models.Finally, based on the data acquired experimentally, a micro-mechanical model was developed. This model has the specificity to take into account the 3D arrangement of the tissue through an idealized but relevant representation of its fibrous microstructure. The macroscopic responses predicted for different loading conditionds could be compared to the experiment for validation. At the microscopic scale, the kinematics of the fibres during the loading could be simulated. The micromechanisms that occur during the deformation of the fibrous network could thus be identified, opening new perspectives in the understanding of the multi-scale properties of the tissue.

O grande volume de resíduos sólidos industriais gerado pelo setor de celulose e papel e o alto custo do seu manejo estimulam pesquisas em busca de soluções mais adequadas para o seu gerenciamento. Uma alternativa que se destaca neste contexto é o aproveitamento destes resíduos em materiais de construção. Este trabalho visa o aproveitamento do lodo de ETE de indústria de papel na produção de compósitos cimentícios para uso na construção civil. Foi estudada a influência de diferentes teores da adição do lodo de ETE (5%,10%,20% e 30% em massa) em argamassa de cimento e areia, com relação água-cimento de 0,65. Determinou-se para o resíduo: teor de umidade; massa unitária; massa específica; pH; sazonalidade de geração e teor de sólidos fixos e para o compósito: massa específica aparente; absorção de água por imersão; absorção de água por capilaridade; retratibilidade; isolamento acústico; resistência à compressão e análise da microestrutura. O resíduo foi classificado como Classe II – A, não inerte e não perigoso, o que indica alto potencial para aproveitamento em materiais de construção. Sua incorporação na argamassa aumentou a absorção de água por capilaridade em 12,76 % e por imersão em 18,93% no traço com 30% de resíduo para a empresa "A". Houve também a diminuição da resistência à compressão com a incorporação do resíduo, entretanto definiu-se o ponto-ótimo de incorporação em 12% para as duas empresas avaliadas, garantindo assim a resistência mínima à compressão de 2,5 MPa, exigência para blocos sem função estrutural. A incorporação de resíduo também apresentou decréscimo na massa específica do compósito de 14% na empresa "A" e de 34% para a empresa "B" para os traços de 30% de resíduo. Os resultados permitem concluir que este compósito é adequado para uso em materiais de construção sem função estrutural. / The large volume of industrial solids residues generated by the pulp and paper sectors and its high management cost stimulate research aiming at finding adequate solutions to its management. An alternative that shows high potential in this context is using these residues in building materials. This work aims at studying the use of paper's mills effluent treatment solid waste in the production of cement composites to be used in construction. The influence of adding different sludge proportions (5%,10%,20% and 30% in mass) in cement and sand mortar, with a water-cement relation of 0,65 was studied. The humidity ratio, unit mass, specific mass, pH, generation season and fixed solid concentration for the residue; and specific apparent mass, water absorption by immersion, water absorption by capillarity, acoustic isolation, compression resistance and microstructure analysis for the composite. The residue was classifies as Class II – A, not inert and not dangerous, which indicated high potential for use as building materials. Its use in the mortar increased the water absorption by capillarity in 12.76% and in immersion by 18.93% in the trace of 30% residue from company "A". There was also a decrease in compression strength when the residue was incorporated, however the optimal incorporation point was defined in 12% for both evaluated firms, guaranteeing the minimum compression resistance of 2.5 MPa, required for block without structural function. The residue incorporation also presented a decrease in the composite specific mass of 34% for company "B" and 1% for company "A" for the traces of 30% residue. The results allow us to conclude that this composite is adequate for use as building materials with no structural function.
