Abstract

The Nicalon SiC fibre offers the possibility of the development of composite materials for use above 1000° C. This study has compared two types of Nicalon fibre, one which was shown to be amorphous and the other microcrystalline with a SiC grain radius of 1.7 nm. Both fibres behaved in a brittle manner when tested in air and in argon up to 1300° C and their strengths fell above 1000° C. There were indications that new defects were created in the amorphous fibre when tested in air above 1000° C. The microstructural analysis showed that as well as SiC, both SiO2 and free carbon were present in both fibres. The segregations of free carbon had a mean radius of 2.0 nm in the amorphous fibre and were grouped into two populations of 1.5 and 2.2 nm in the microcrystalline fibre.
