Mechanical-property enhancement in ceramic-matrix composites. Interim report

The interfacial strength between AVCO SCS-6 filaments and a borosilicate glass matrix was measured using an indentation push-in technique. Crack-filament interactions were investigated using a fracture-mechanics technique (DCDC). An ultraviolet curing technique, coupled with hot pressing was developed to prepare SiC filament-borosilicate glass composites.
