In this study, carbon/polyamide 6 staple fiber yarns were heated above the melting temperature of the polymer in a modified impregnation and calendaring process using two hot air blowers, stretched to align the fibers in the yarns, and formed into tapes. Tapes were produced at different process temperatures and the influences on the degree of consolidation and the thermal properties of the tapes were characterized. While improved impregnation quality can be achieved at higher temperatures, a decrease in the crystallization peak temperature of the impregnated tape was observed, indicating thermal degradation.
