Increasing Adhesion of Carbon Fiber Filler to Polymer by Sizing - a Review

The problem of increasing adhesive interaction at the interface between a carbon-fiber-reinforcing filler and a polymer matrix and the dependencies of mechanical properties of carbon-fiber-reinforced plastics on the strength of fiber-matrix bonding is studied. The mechanisms determining occurrence of adhesive interaction between the components in the caron-fiber-reinforced plastic and the factors affecting the adhesion strength at the interface are explained. It is shown that adhesive interaction can be increased by modifying the surface of the carbon-fiber-reinforcing filler using the sizing method. The results of the studies in this direction are reviewed.
