| Outline of Final Research Achievements |
An in-situ forming technique of carbon fiber reinforced thermoplastic (CFRTP) composites is studied, in which impregnation and lamination processes are operated simultaneously in a single manufacturing process. For this purpose, a manufacturing device which consists mainly of a diode laser and a compaction roller is developed. The results show that the bending modulus and strength of CFRTP fabricated by the present manufacturing device are as high as the ones obtained by a conventional hot press machine. A three-dimensional visualization method with high-speed stereo cameras is developed to analyze the deformation dynamics of CFRTP during the impact fracture. The obtained results suggest that the interfacial adhesion between carbon fiber (CF) and resin, and the property of resin strongly affect the impact fracture processes. Based on this observation, a new surface treatment for CF improving the impact strength is proposed for future application.
