Interface modification can also be achieved by surface treatments such as chemical etching of the metallic reinforcements in as-received or pre-oxidized condition prior to the composite fabrication. Moore and Kunz showed that in glass matrix composites containing metal particles, acid etching of pre-oxidized metal particles generates extensive, uniform surface roughness and that the cracks proceed along the roughened contour of the particles during the composite fracture. As a result, fracture toughness in this composite improved considerably with such a surface treatment of metal particles. The aim of the current project is to evaluate the effects of these treatments on the interfacial characteristics, and to elucidate the pull-out process of these treated reinforcements from the matrix, in a ceramic matrix composite with unidirectional metallic ribbon reinforcements.
