High temperature mechanical behaviour of an uncoated SiC-SiC composite material
- 134 Downloads
Flexural tests have been performed on unnotched specimens of an uncoated SiC-SiC laminar composite material to check the influence of specimen thickness and temperature (22 to 1200‡C in air) on the strength and the elastic modulus. An important modification of the loading curves and crack paths occurred when the temperature was increased, corresponding to a strengthening of the fibre-matrix interface.
