| Abstract: | B 4C coating on M40JB carbon fiber was prepared by infiltration-pyrolysis with poly(p-phenylene) borone as precursor, the carbon fiber reinforc ed SiC composites were fabricated through infiltration, winding, cut, molding and hot-pressing with polycarbonsilane(PCS) as binder. The feasibility of the process wa s investigated, the microstructure and mechanical properties of the Cr/SiC comp osites was characterized. The results show that B 4C coating exhibited significant eff ect on the mechanical properties of the composites. |
