Fiber-matrix interfacial effects in carbon-fiber-reinforced glass matrix composites

The rationale behind the development and use of carbon-fiber-reinforced glass matrix composites along with their characteristic behavior is reviewed. The effect of the fiber-matrix interface on composite performance is examined for two different situations. In one study, the nature of the fiber-matrix interface was altered through reactions between the carbon fiber and various dopants in the matrix. The other investigation addresses differences in the mechanical performance of glass matrix composites reinforced with carbon fibers made from PAN and pitch-derived precursors. In both cases, composite performance is correlated with analysis of the fiber-matrix interface.
