Metallic implants have been used widely in a lot of orthopaedic applications. Titanium, Ceramics,medical grade titanium and other metal alloys are inserted in large bones designed as artificialjoints. Plates and bars are also attached to bones in order to facilitate healing of fracturedbones. The disadvantages of metal implants however are corrosion and the release of ions, sothere is need for finding new orthopaedic materials like composites, which have a closer densityto the natural bone too.This project is part of European project NEWBONE and it is based on the manufacturing andprocessing of glass fiber reinforced composite and the assessment of its properties.The goal of the project is to manufacture composite parts in the lab in different designs and dimensionswhich are suitable for mechanical and chemical tests.The theoretical work deals with the processing methods and the medical composites, medical devices,plastics, reinforcement of medical composites, PEEK and carbon fibers and other materials.The glass fibers are impregnated with dental curing resin. The residual void content, glass fibercontent and chemical and mechanical properties are estimated by ASTM standard methods.Results are resented according to evaluation of composite performance mechanically and chemicallyand show the best choice of composite parts in order to improve future use of orthopaedicapplications.
