Although much interesting research on carbon foams has been published, their thermal conductivity and compression properties are not fully understood because of complexity of porous and brittle structure. These properties are critical for applying carbon foams in thermal management, composite tooling, and shock resistant applications. Special test methods are needed for accurate characterization of thermal and compression properties of carbon foams. This paper describes improved methods for measuring the thermal conductivity and compression properties of carbon foams. The thermal conductivity was measured and validated using a heat flow meter technique that was built in house and the compression properties were measured using end-potting technique. The results from improved techniques were compared with that of standard techniques. Compared to standard techniques, the improved techniques resulted in accurate measurement of thermal conductivity and compression properties with consistent and reproducible test data. Thus, these techniques are recommended for measuring the thermal conductivity and compression properties of carbon foams and similar open-cell brittle foams.
