When a non-destructive ultrasonic inspection procedure has to be specified it is necessary to know the acoustic properties of the material concerned. Two continuous ceramic fibre composites, an Al(2)O(3)/SiC and a SiC/SiC, were studied in order to determine their acoustic properties such as attenuation and propagation velocity. The classical methods normally used to determine these properties fail due to the strong inhomogeneity and high attenuation of the materials considered. Furthermore the anisotropy of the material must be taken into account. Some of the possibilities and limitations of these materials are discussed with respect to ultrasonic characterisation.
