摘要：

The microstructure of Nicalon-reinforced borosilicate glass was studied using scanning acoustic microscopy (SAM) and scanning electron microscopy (SEM). Acoustic micrographs exhibited high contrast, and the formation of Rayleigh-wave-interference fringes both within and around fibres allowed the in-situ-fibre and matrix elastic moduli to be estimated. The matrix was found to have undergone partial devitrification resulting in the formation of cristobalite. The presence of a high volume fraction of reinforcing fibres was found to have little effect on cristobalite formation and distribution. The thermal expansion mismatch between beta-cristobalite to give rise to extensive microcracking around individual cristobalite grains and partial fibre/matrix debonding.
