Thermophysical and Mechanical Properties of SiC/SiC Composites …

The themophysical properties of SiC/SiC composites (particularly thermal conductivity)are also dependent on the fabriion procedure. The measured instantaneous coefficient ofthermal expansion (ath) for SiC/SiC composites fabried with cg-Nicalon fibers (40 vol.%fibers) are 2.5-3 ppm/ûC, with no pronounced dependence on temperature between 20 and1000ûC [5,14]. The lower value refers to through-thickness measurements on 2-D composites,and the higher value refers to in-plane measurements. The bulk SiC value is 2.2 ppm/ûC at roomtemperature and 5.0 ppm/ûC at 1000ûC, with an average value between 20 and 1000ûC of 4.0ppm/ûC [11,12]. The specific heat at constant pressure (CP) varies from 620-640 J/kg-K at 20ûCto 1200-1250 J/kg-K at 1000ûC for both monolithic SiC and SiC/SiC composites, …
