DISTINCTIVE FEATURES OF CMCs 1. The general philosophy in nonceramic matrix composites is to have the fiber bear a greater proportion of the applied load. This load partitioning depends on the ratio of fiber and matrix elastic moduli , E f /E m and this ratio can be very high . In CMCs, this ratio is rather low. 2. Another distinctive point regarding CMCs is that because of limited matrix ductility and generally high fabrication temperatures, thermal mismatch between components has a very important bearing on CMC performance ....
