Interfacial Adsorption and Crystallization of Polycarbonate in Carbon Fiber Composites

Abstract

A polycarbonate (PC)/carbon fiber (CF) composite system has been examined with regard to interfacial adsorption and crystallization by altering times and temperature of annealing. Times up to 180 min and temperatures of 245, 275, and 300 C have been investigated. Traverse tensile, transverse toughness, and scanning electron microscopy results on unidirectional, continuous-fiber composites indicate improved fiber/matrix adhesion at longer times and higher temperatures of annealing. Improvements in transverse toughness and transverse tensile strength of a factor of two is achieved. Keywords: Adsorption; Crystallization; Polycarbonate; Carbon fiber; Composite materials; Physical properties; Thermoplastics.
