Abstract

Abstract

Compared with high pure graphite, the internal friction characteristics of pyrolytic carbon matrix carbon-carbon composites were studied in the present work. According to experimental results, two internal friction mechanisms are proposed: thermoelastic and static hysteresis mechanisms. The effects of interface between carbon fibers and carbon matrix play important roles on the internal friction characters of carbon-carbon composites, which leads to some unique internal friction phenomena in carbon-carbon composites.
