Abstract

Carbon fiber/polyamide 6 (CF/PA6) composites were prepared via film melt impregnation and their crystallization and mechanical properties were studied. The non-isothermal crystallization behavior and mechanical properties of polyamide 6 and CF/PA6 were investigated at different cooling rates. The crystallization time of CF/PA6 decreased depending on the cooling rate compared to that of polyamide 6. The carbon fibers likely acted as nucleating agents in the polyamide 6 matrix. The flexural strength of the composites increased when manufactured at lower cooling rates due to the effects of increased crystallinity as the crystallization continued for a long time. In addition, as the cooling rate increased, the impact resistance increased.
