Abstract
Matrix cracking initiation stress (MCIS) in fiber-reinforced ceramic composites is determined by measuring electrical resistance changes of thin Au film sputtered on the tensile surface of composite as a function of applied stress in three-point bend tests. MCIS for 50 vol% SiC-Li aluminosilicate matrix composite is 370 plus or minus 10 MPa. Mild etching has little effect on MCIS. MCIS of 45 vol% C fiber-reinforced borosilicate matrix composite is 360 plus or minus 2 MPa. Mild etching results in an almost twofold increase in MCIS to over 650 MPa. (meeting proceedings)
