Oxidation of silicon carbide (SiC)-based ceramic composites with a boron nitride fiber/matrix interphase has resulted in rapid degra-dation and consumption of SiC fibers in some cases. It is believed that boria formed from the oxidation of boron nitride accelerates SiC oxidation by many orders of magnitude, yet the mechanism is poorly understood. fiber-based composites (40 vol.% fibers) ranging from to GPa at room temperature . The corresponding YoungÕs modulus for a SiC/SiC composite fabricated with Hi-Nicalon fibers was GPa. Values approaching GPa would be expected for high-quality, low-porosity SiC/SiC composites fabricated with Sylramic or Hi-Nicalon type S Size: KB.

KEYWORDS: SiC fiber, high temperature, fiber tensile strength, oxidation, creep, ceramic matrix composites INTRODUCTION SiC-based fibers, which have high tensile strength, high elastic modulus and good thermal stability, are one of the most promising candidates for the reinforcement of ceramic matrix composites (CMCs) .
In recent years, it has been increasing in demand for high performance CMCs for high temperature application. CMCs are most promising materials for high temperature structural materials of gas turbines for aerospace and power generation. Mechanical performances of CMCs are highly dependent on properties of the reinforcement.
