摘要：

Interfacial shear strength and frictional stress of fiber-reinforced titanium alloy matrix composites were determined using indentation and fragmentation tests. The influences of fiber surface chemistry, matrix alloy composition, microstructure and prolonged thermal exposure on the interfacial properties were investigated. The interface failure resulting from indentation loading was characterized using scanning electron microscopy. Also, the influence of interfacial reactio: on the strength of the fiber was determined. Results indicate that the mechanical properties and failure characteristics of the interfacial region depend on fiber surface chemistry, matrix microstructure, and residual stresses at the interface.
