Study on Carbon Fiber Reinforced Chloroprene Rubber Composites

Due to the low strength of ordinary rubber, poor high temperature resistance and abrasion resistance, limit their service life. In this paper, the high-performance carbon fiber (CF) was used as a reinforcement, the chloroprene rubber (CR) as the matrix, and coupling agent as a compatilizer, prepared carbon fiber/rubber composite materials. The content of carbon fiber was determined by testing the mechanical and thermal properties. The effect of coupling agent on the compatibility between rubber and carbon fiber was studied by using as a bonding agent. The compatibility of the carbon fiber and rubber were analyzed by scanning electron microscope (SEM). The results show that the formula obtained best mechanical properties is 100 phr chloroprene rubber, 12 phr carbon fiber, and 2.5 phr KH-550. And further demonstrate that compatibility of carbon fiber / chloroprene rubber with adding 12phr CF by SEM analysis.
