Outline of Final Research Achievements

Fiber-reinforced composite materials (FRP, usually used with thermosetting resin) are high strength and high elastic modulus, and it is widely developed and used in wide fields such as airplanes and automobiles.Because of the difficulty in recycling and long molding time of FRP, the use of reusable　thermoplastic resins as matrix is a research trend. However, the FRTP which produced by the continuous fiber reinforced thermoplastic (FRTP) molding method has lower fiber content than FRP and its strength is only about 1/3 of FRP.In this research, we propose using FRTP solvent semi-prepreg molding method.A new type of multi-functional FRTP was realized with the same effort as the conventional FRTP molding method and has FRP-like strength.In addition, we also proposed a high cost performance CFRTP recycling method that is suitable for FRTP and confirmed its effectiveness.
