Wave Propagation in the Presence of Interface Layers in Composites

Abstract

In composites (particularly metal matrix composites reinforced by fibers and particles), it is often the case that there is an interface layer surrounding the fibers or particles induced by processing conditions. This layer has properties different from those of the matrix and the reinforcing phase. The strength and fracture behavior of the composite is significantly influenced by this interface layer. It is, however, difficult to characterize this layer non- destructively. Ultrasonic techniques provide a means to characterize mechanical properties of the interface regions. In this paper we present results showing the effect of interface layers on scattering cross sections of spheroidal inclusions. (JES)
