Abstract
Carbon Fiber Reinforced Plastics (CFRP) have been attracting attention in the
automotive industry for their light-weighted properties. Thermoset plastics are
mainly used as a matrix of CFRP in the aerospace industry. Thermosetting resin
takes a long time for molding and this results in high costs. On the other hand,
Carbon Fiber Reinforced Thermoplastics (CFRTP) are recyclable, good in
productivity and excellent in impact strength. Thus, they are expected to be
widely applied within the industry. Polycarbonate (PC) is excellent in impact
resistance that does not change even at low temperatures. Therefore, PC can be
expected to be applied as matrices of CFRTP. PC with higher-molecular-weight
improves its impact resistance, but at the same time, increases its viscosity and
deteriorates impregnation of the continuous fibers. Therefore, improvements in
moldability of CF/PC are required. To improve the quality of the molded CF/PC,
CF/PC thermoplastic prepreg, in which carbon fabrics or unidirectional carbon
sheets are pre-impregnated with PC, were developed. In this study, carbon fiber
reinforced polycarbonate (CF/PC) laminated composites were molded with
thermoplastic prepregs of unidirectional (UD) sheets; moldability and
mechanical properties of CF/PC laminated composites were evaluated.
Keywords: carbon fiber, polycarbonate (PC), thermoplastics, CFRTP, UD sheet,
thermoplastic prepreg.
