Abstract: A composite structure forming method according to the present invention comprises the steps of first pre-treating brittle material fine particles to impart an internal strain to the brittle material fine particles, secondly causing the brittle material fine particles in which the internal strain has been created to collide with a substrate surface at high speed or applying a mechanical impact force to the brittle material fine particles containing the internal strain therein provided on the substrate surface, to deform or fracture the brittle material fine particles, re-joining the fine particles through active new surfaces generated by the deformation or fracture, forming an anchor section made of polycrystalline brittle material of which part bites into the substrate surface at a boundary section between the new surfaces and the substrate, and further forming a structure made of polycrystalline brittle material on the anchor section.

Abstract: A method for reducing static electricity on the surface of a shaped article made of polyvinyl chloride resins, which method comprises the steps of (a) blending a surface active agent with the polyvinyl chloride resin prior to fabrication of the resin into a shaped article, (b) fabricating the resin admixed with the surface active agent into a shaped article, and (c) subjecting the shaped article to a treatment with low temperature plasma of a gas.

Abstract: The invention provides carbon fibers having mechanical properties equivalent to or even better than those of the polyacrylonitrile-based carbon fibers from a bituminous material, e.g. coal tar pitch, as the starting material. The starting pitch is first partially hydrogenated in tetrahydroquinoline under specific conditions followed by a heat treatment to give a pitch composition suitable for spinning which can be characterized by several parameters including the proportions of the carbons and hydrogens having different chemical shifts in the NMR analysis. The pitch composition for spinning is then subjected to spinning under specific conditions including the temperature condition for controlling the viscosity behavior of the molten pitch composition determined by use of the Andrade's equation and the pitch filament is then infusibilized in an oxidative atmosphere and carbonized in an inert atmosphere into carbon fibers having a tensile strength of at least 200 kg/mm2 and a tensile modulus of at least 10 tons/mm2.
