Fatigue Behavior of Silicon Carbide Fiber Reinforced Lithium-Alumino-Silicate Glass-Ceramics

Abstract

The mechanical fatigue behavior of Nicalon silicon carbide-type fiber reinforced lithium-alumino-silicate glass-ceramic matrix composites (SiC/LAS) was examined as a function of matrix composition and fiber ply lay-up. Both tensile and flexural fatigue behavior were determined at room temperature in air. The results are discussed in terms of the effect of the non-linearity in the stress-strain behavior on the fatigue life of these composites as well as the effects of applied stress state. Differences in fracture surface appearance are related to composite matrix composition and ply lay-up.
