    摘要: Self-adhesive carbonaceous grains for use in the production of high density carbon artifacts and high performance carbon-carbon composites are made by processes such as oxidation and heat treatment of specific mesophase pitches. The present carbonaceous grains exhibit excellent binding properties, shape stability when molded, and high density with higher carbonization yield, providing very high strength artifacts when their properties fall within the specific range of properties defined by their H/C and O/C values. High density carbon artifacts can be easily obtained by molding the grains and carbonizing or graphitizing the same.

    摘要: Process for producing a copper plated resin article by forming a uniform copper coating having excellent adhesive strength on a fiber-reinforced or unreinforced thermoplastic or thermosetting resin article having a heat deformation temperature higher than 165.degree. C. The resin article is heated along with a source of copper formate under a reduced pressure or in a non-oxidative atmosphere to a temperature in the range above 165.degree. C. but lower than the heat deformation temperature of the resin article. The process makes it possible to produce a resin article having formed thereon a copper layer having an excellent adhesive strength by a very simple manner, and the resin article thus obtained can be used in various industrial fields.

    摘要: A process for making carbon fiber reinforced materials which not only have desirable qualities which include high strength, high heat resistance, chemical resistance, wear resistance and lightweightness but also which are produced in a short time and at low cost. The process includes the steps of impregnating a carbon fiber assembly with a melt of mesophase pitch or mixing short carbon fibers with the mesophase pitch, shaping the pitch-impregnated assembly or the pitch/short carbon fiber mixture, and firing the same. The process requires that the mesophase pitch used in the process be almost 100% of an optical anistropic phase as examined under a polarizing microscope; have a softening point of no higher than 350.degree. C. and be capable of being carbonized in a yield of at least 70% when gradually heated to a temperature of about 600.degree. C. in an inert gas atmosphere and then held at that temperature for two hours.
