摘要: A slurry containing a precursor fiber convertible to carbon and/or and, based on 100 parts by weight of the fiber, 10 300 thermosetting resin, e.g. phenol is processed into random web. This web may contain pitch or an organic granular material. The hot-pressed between pair belts while curing resin inhibited prepare prepreg sheet. sheet disposed, leaving clearance, in mold having ribs molding surface and heated over melting point for expansion complete cure provide porous composite equipped with grooves. carbonized graphitized produce carbonaceous material use as fuel cell electrode so on. has high homogeneity, gas permeability, electrical conductivity, heat conductivity mechanical strength.
