Abstract: | Research and development efforts on high-temperature, oxidation-resistant fibres have increased over the past decade due to
the demand for light-weight, stiff and strong composite materials in aerospace applications. Varieties of ‘high-performance’,
continuous, non-oxide fibres with low-density, high tensile strength and tensile modulus have been developed either from organic
precursors or via chemical vapour deposition for fabrication of ceramic matrix composites. Fibres derived from polymer precursors
(e.g. Nicalon, Tyranno, HPZ) are small in diameter (compared to CVD monofilaments) and are ideally suited for ceramic composites.
Processing, microstructural stability and mechanical properties of these newly developed SiC and Si3N4 base fibres are briefly reviewed in this paper. |
