Development of Colloidal Technique for Enhancement of Performance of Carbon Fiber Reinforced Thermoplastic

Abstract

This study showed the development of the colloidal technique for enhancement of the interfacial adhesion between the carbon fibers and the thermoplastic resin, such as nylon. To improve the interfacial adhesion between carbon fiber and nylon, the nylon particles in the polymer colloids were adsorbed on the carbon fiber using electrophoresis. The amount of nylon particles adsorbed on the carbon fiber was able to be controlled changing the applied voltage in the electrophoresis for a short time. Accordingly, the interfacial shear strength between the carbon fiber and the nylon was also controlled through the surface modification by the present system. This method was a basic technique for making carbon fiber-reinforced thermoplastic （CFRTP） with high performance.
