The PCS-P miscellanies have been obtained to blend polycarbosilane (PCS) with coal pitch (P). The SiC-C fibers have been obtained by spinning，preoxidation，heat treatment of these PCS-C miscellanies. The resistivity，strength and modulus of these fibers decrease with the increase of the carbon contents. The composites composed of the SiC-C fibers and epoxy resin have good electromagnetic wave absorption properties.
