The fiber-matrix interfacial properties of several glass and ceramic matrix composites have been determined using two indentation techniques and a single-fiber pull-out technique. An instrumented indenter was developed to improve the acquisition and analysis of the data. The effects of thermal-expansion mismatch were determined from three model composite systems containing large SiC monofilaments using the single-fiber pull-out test. An indentation push-out test was successfully used to determine the debond strength of a borosilicate matrix/SiC monofilament/carbon core material. A comparison of the various techniques for determining the fiber-matrix interfacial properties was conducted.
