Abstract

Performance and property evolution of cross-ply and quasi-isotropic laminates made of 2-D plain weave Nicalon* reinforced enhanced SiC matrix composite subjected to fully reversed cyclic fatigue at 982 °C are presented. Also results obtained from a number of various damage monitoring techniques such as stiffness measurement, dissipated energy per cycle and phase lag calculation used in keeping track of damage evolution are reported. From interrupted fatigue tests, remaining strength as a function percentage of cycled life for various load levels are reported. Fatigue test results indicate quasi-isotropic laminates are slightly more damage tolerant than the cross-ply laminates.
