A Model Stress Analysis of Swelling in SiC/SiC Composites as a Function of Fiber Type and Carbon Interphase Structure

Abstract

A continuous fiber composite was simulated by four concentric cylinders (consisting of fiber, fiber/matrix interphase coating, matrix, and surrounding composite) to explore composite stresses when irradiation swelling of the various components is included to study radial debonding at the fiber-coating interface as a function of neutron dose. SiC Type-S and Hi-Nicalon fibers, and three types of transversely isotropic carbons for the fiber coating were considered.
