Effect of Water Immersion on Fiber/Matrix Adhesion

Abstract:

A study was made on the effect of water immersion on fibermatrix adhesion in composites. Representatives of the four main classes of continuous fiber composites were tested glassthermoset, carbonthermoset, glass thermoplastic, and carbonthermoplastic. Water conditioning was done by immersion in 50 deg C distilled water. The only class of composites degraded by water was glass-reinforced thermoplastics. However, carbon-reinforced vinyl esters, a subset of the carbonthermoset class, appear to have weak fibermatrix bonds when dry, and these bonds are further degraded by water. In both cases, immersion in water hydrolyzed the interfacial bonds and caused large, irrecoverable property reductions.
