This paper discusses the effect of thermal shock on the mechanical properties of some ceramic matrix composites manufactured by the sol-gel process. The composites were prepared by the freeze-gelation of aqueous sols of two different matrix compositions, each containing about 10vol% of Saffil alumina fibres. The properties of one composite remained almost unaffected by the thermal shock, while those of the second material remained unaffected up to about 300°C and then fell smoothly as the water-quenching temperature was further increased to 600°C.
