Stress relief medium

A number of systems investigated as possible carbon fiber sizes are given in Table 9.8. Dauksys [24] attempted to apply a size to form a microductile region adjacent to the interface, which could act as a stress relief medium, a crack inhibitor/arrestor and also attempt to increase the effective transfer length of the fractured fibers. Dauksys, at best, applied a 0.9 /w solution of polyhydroxyether in Cellusolve to Thornel 50 carbon fiber (with the PVA size removed) and from composites prepared from Union Carbide ERL2256 resin,...
