The work described is primarily related to the development and use of several techniques for determining the fiber/matrix interfacial properties of ceramic and glass matrix composites. The specific techniques utilized are the double cleavage drilled compression (DCDC), indentation push-in, indentation push-out, and single fiber pull-out tests. The DCDC test provides direct experimental observation of the crack-fiber interactions. The indentation techniques and the pull-out test provide information on the debond strength of the fibers from the matrix and interfacial frictional stress required to pull the fibers out of the matrix. The emphasis has been on understanding what happens at the interface, and has focused on several model systems including SiC monofilament reinforced glasses (borosilicate, soda-lime-silica), and SiC fiber reinforced glass-ceramic. Measurements have been made of the interface properties as well as on the increase in toughness as a crack approaches the reinforcing fibers. Some of the effects of interface chemistry on the properties have also been considered.
