DEVELOPMENT OF ACRYLATE RESIN FOR CARBON FIBER REINFORCED PLASTICS

摘要

Carbon fiber reinforced plastics (CFRP) are more and more widely used in civil aircraft. The weight savings they provide make them very attractive for major structural components such as fuselage and wing. Epoxy resin is mainly used for them because it has good mechanical and thermal properties. We have been developing acrylate resins applied for matrix resins of CFRP suitable for components of aircraft. Acrylate resin is cured by radical chain polymerization. Therefore, it could be cured during a shorter time than conventional epoxy resin cured by step polymerization. In this study, a new acrylate resin suitable for components of aircraft has been developed. It has enough viscosity suitable for manufacturing prepregs. Nevertheless, it could be cured by ultraviolet light and showed appropriate glass transition temperature. CFRP with this new acrylate resin also investigated. Its mechanical properties stood comparison with the properties of CFRP with epoxy resin.
