| 摘要 |
Thick, three-dimensional structures comprising discontinuous thermoset pitch fibre, and composites comprising such structures embedded in a matrix material such as a thermoset resin, ceramic, metal or carbon. Carbon-carbon fibre composite articles produced from porous carbon preforms obtained by carbonizing such structures followed by infiltration with pyrolytic carbon using CVD processes, which exhibit surprisingly high through-thickness thermal conductivity and isotropic properties. <MATH> |
