PRODUCTION OF HIGH STRENGTH C/C COMPOSITE MATERIAL

摘要

PURPOSE:To produce a high strength C/C composite material reducing deviation of characteristics (anisotropy of strength) and enabling leveling-up on an average. CONSTITUTION:A thin layer of hardly graphitizable carbon is placed at the interface between easily graphitizable carbon layers each consisting of carbon fibers and mesophase pitch and the layers are combined to produce a pitch-based high strength C/C composite material By this method, the occurrence of anisotropy in the matrix layers is controlled and the mechanical strength of the composite material is remarkably enhanced.
