Ultrasonic Characterization of Ceramic-Ceramic Composites
Ceramic-reinforced ceramic matrix composites are being developed for high temperature, high strength applications such as heat engine components, heat exchangers, and recuperators. The particular material considered here is a SiC-fiber-reinforced SiC matrix composite formed by chemical vapor infiltration (CVI). The initial focus was on porosity, which has been linked to the material strength. Ultrasonic attenuation and velocity were investigated since they were expected to be affected by the porosity in the material.[2–4]
