抄録

Thermal propagation and diffusion in the carbon fiber (CF)/thermoplastic (TP) model composites, which was composed of a single CF and thin TP films, were investigated as a basic research of a rapid carbon fiber reinforced thermoplastic (CFRTP) molding by microwave irradiation. In case of the CF/TP model composite with thermally-conductive matrix prepared from polypropylene (PP) and 5 vol.% hexagonal boron nitride (h-BN) powder, the thermal propagation in the matrix was enhanced till 2.3 times as compared to one with PP of the conventional matrix of 0.15 W/(m·K). Its thermal propagation agreed with the one-dimensional heat equation. Moreover, the thermally-conductive matrix led to the suppression of thermal decomposition at the interface between CF and matrix in composites.
