摘要：

Ceramic-matrix composites have been produced using unidirectionally aligned Textron SCS-6 fibres in a sintered reaction-bonded matrix. A tape-casting technique was used to produce a prepreg sheet that could be cut and stacked to form a layup. Al2O3 and Y2O3 were used as sintering aids, final sintering being carried out in a hot press at 1700-degrees-C. Matrix, fibre and interfacial microstructure has been characterized using analytical microscopical techniques. X-ray mapping of the carbon and silicon distribution at the fibre-matrix interface was carried out, and evidence of reaction between the outer carbon-rich layer of the fibre and the matrix was found. Micromechanical behaviour of interfaces has been investigated and compared with interfacial microstructure and macromechanical properties.
