No. of bitstreams: 1 BRUNO MOURA MIRANDA - DISSERTAÇÃO (PPGEG) 2015.pdf: 9948864 bytes, checksum: 4dfc5042bae3dedf54ac975413988ca9 (MD5) Previous issue date: 2015-02-27 / O objetivo deste trabalho foi desenvolver um equipamento de injeção de resina para processar compósitos via moldagem por transferência de resina de uso laboratorial. Foi cumprida a seguinte metodologia: concepção, fabricação e testes no equipamento, testes de injeção nas estações de processamento, fabricação de placas compósitas e posterior caracterização. Os materiais utilizados nos experimentos foram: Manta de fibra de vidro (450g/m2), tecido básico de fibra de vidro (600 g/m2) e resina poliéster insaturada ortofitálica de média viscosidade Arazyn 1.0 #08 Ara Ashland ® e catalisador Butanox 50. Foram produzidas placas de pequena área, com dimensões de: 175x125x5mm e de grande área, com dimensões de: 340x340x5mm. Baseado nos experimentos resultados, conclui-se que foi possível o projeto, desenvolvimento e fabricação de um equipamento de injeção de resina por RTM de uso laboratorial, de baixo custo, com baixas perdas energéticas, para fabricação de compósitos com reforço dos tipos: manta e tecido, com diferentes gramaturas e pequena espessura. / The objective of this work was design a laboratorial Resin Transfer Moulding Equipment to process composites. The following methodology was fulfilled: Design and manufacture of the equipment, testing its process capabilities, injection tests in the processing stations, manufacturing of composite plates and further characterization. The materials used in the experiments were glass fiber mat (450g / m2), base glass fiber fabric (600 g / m2), a medium viscosity 1.0 Arazyn Ara Ashland ® # 08 unsaturated polyester resin and 50 Butanox. Small and large area plates were produced with dimensions of: 175x125x5mm and 340x340x5mm respectively. Based on the experiments results, it is concluded that it was possible the design, development and manufacture of a resin injection equipment RTM for laboratory use with low cost and low energy losses, for the manufacture of composites with two reinforcement kind: mat and fabric, with different weights and thin.
