Part of the NATO ASI Series book series (NSSE, volume 173)


The role of interfaces in the strength of composites is discussed through a comparison of fracture processes in elastically homogeneoeus materials versus bimaterials. Following this the fracture strength of fibrous composite interfaces are briefly reviewed. Experimental results for the temperature variation of interfacial shear strength in a fibrous composite are presented. A microstructural investigation of the regions where failure occurs is made by scanning and transmission electron microscopy. Based on the microstructural study, a rationale for the failure of the composite under study is offered.
