Barium magnesium-aluminosilicate glass-ceramic matrix composites containing SiC (Tyranno) fibres have been studied with a view to their application in low density rigid structures which demand corrosion resistance to relatively high temperatures (T<1100 degrees C). The tensile stress-strain behaviour has been evaluated over a range of temperatures and the importance of the environmental degradation of the carbon-rich interface in determining the composite mechanical behaviour has been addressed. The notch insensitivy, being a key factor in application of shaped components, mechanical interconnects and surfaces subjected to accidental mechanical damage was demonstrated by measuring the mean failure stress for tensile specimens containing plane notches of differing depth. The materials response under creep and cyclic-creep conditions was also investigated. The existence of extensive creep strain recovery on the unloading cycle was found, which was attributed to matrix compression by elastically strained fibres.
