Fiber-composite material and method for producing the same

摘要

A fiber-composite material includes: 55-75 wt % of carbon, 1-10 wt % of silicon and 10-50 wt % of silicon carbide, and the matrices including Si-SiC-based materials formed integrally among assemblages of yarns include carbon fibers integrally formed and combined three-dimensionally so as not to separate from each other. The fiber-composite material has a coefficient of kinetic friction of 0.05-0.6 and a porosity of 0.5-10%.
