Abstract

Abstract: In order to improve the tensile properties of high modulus carbon fibers, the tensile strength and elongation at break of CCM40J and CCM55J carbon fibers before and after resin dipping were studied. It is found that twisting can improve the tensile properties of carbon fiber. Compared with CCM55J carbon fiber, the tensile strength and elongation at break of CCM40J carbon fiber increased by 17% when the twisting was 10 n/m. In order to improve the tensile properties of two high modulus carbon fibers, the optimal twist and dipping method were determined.

Key words: twisting, tensile strength, elongation at break, high modulus carbon fiber, composites
