Effect of High Temperature Environment on the Tensile Strength of Carbon Fiber/Highly Heat Resistant Polyamide Resin

Abstract

Carbon Fiber Reinforced Thermoplastics (CFRTP) are expected to be used in the automobile parts. Since the automobile parts can be subjected to the temperature up to 120 °C, the mechanical properties of CFRTP under high temperature environment should be evaluated. Although Polynonamethyleneterephthalaamide (PA9T) is an expected candidate as the highly heat resistant resin to be used for the matrix of CFRTP, the mechanical properties of CFRTP using PA9T under high temperature have not been clarified yet. In this study, the effects of molding conditions on the mechanical properties of CFRTP using PA9T were evaluated and its tensile strength under high temperature environment was measured.
