Abstract

This paper studied the oxidation behavior of the Nicalon and Hi-Nicalon type of continuous SiC fibers. The fibers were exposed in air at 1000-1400°C for 1h. Experimental results indicate that both Nicalon and Hi-Nicalon SiC fibers’ tensile strength decrease, whereas oxygen content increase with rising oxidizing temperature. The XRD results showed that the crystallinity of Hi-Nicalon is better than Nicalon fibers. The amorphous oxide film began to crystallize into cristobalite at 1400°C. By comparing the same conditional experiments for Nicalon and Hi-Nicalon SiC fibers, the differences between Nicalon and Hi-Nicalon SiC fibers about the antioxidant properties and the effect of heat treatment on the structure and properties of SiC fibers have been discussed.
