It as a series of excellent performance, suc as ig specific strengt , ig specific modu lus, ig temperature resistance, corrosion resistance, fatigue tolerance, creep resistance, electrical conductivity, eat transfer and small expan sion coefficient. So it can not only be a structuralm aterial bearing eavy loads, but also play a role as functional materials. M eanw ile, Carbon/Carbon( C /C) composites ex ib it excellent structural properties at elevated temper atures, and are considered as t emost prom ising candidatematerials for ig temperature applications suc as in a viation and space flig t industries.
