Abstract

Fully-reversed cyclic fatigue response of 2-D woven SiC_f(Nicalon) fiber reinforced enhanced silicon carbide (E-SiC) matrix composites were investigated at 982°C under various load levels. Maximum applied cyclic stresses above the matrix cracking stress (critical stress) resulted in significantly shorter fatigue lives. Cyclic effect was also investigated by performing interrupted fatigue tests at the 'early,' 'middle,' and 'late' stages of fatigue damage development. Oxidation may play a significant role.
