Carbon Fiber Reinforced Glass Matrix Composites for Space Based Applications.

Abstract

High elastic modulus (HMU) carbon fibers were combined with several different glass and glass ceramic matrix compositions. The importance of the fiber matrix interface in the control of composite performance was central to the investigation and was evaluated by correlating mechanical properties with microstructural and microchemical analysis of the interfacial region. LAS glass-ceramic matrix composites. Carbon fiber reinforced glass matrix composites of 0/90 orientation were found to be relatively notch insensitive. Lowering of the processing temperature of 7740/HMU composites was found to affect composite mechanical performance through matrix consolidation effects. Interfacial reactions between the carbon fiber and various matrix additives (nb205, mo03) were found to have a profound effect on composite mechanical behavior via formation of an interfacial carbide layer which increased fiber-matrix interfacial bond strength.
