Description

An understanding of the dependence of the fiber-matrix interface deformation and debonding on residual stresses, the fiber-matrix bond strength, and matrix properties under transverse loading conditions is needed for the improvement of the transverse properties of titanium matrix composites (TMC) reinforced with continuous silicon carbide (SiC) fibers. This paper presents a new methodology to assess the interfacial stress at fracture. The newly developed method is based on an ultrasonic NDE technique which is used in-situ to monitor the deformation and failure of the fiber-matrix interface under transverse loading.
