    Abstract: PURPOSE:To obtain flameproof fiber having high mechanical characteristics with hardly any bonding between mutual single fibers in excellent productivity by flameproofing or infusibilizing a precursor of the flameproof fiber under ordinary or reduced pressure in the initial period and then flameproofing or infusibilizing the resultant fiber under pressure in the latter period. CONSTITUTION:A precursor of flameproof fiber (preferably having in the initial flameproofing) and then flameproofed or infusibilized under pressure in the latter period to afford the objective fiber.

    Abstract: PURPOSE:To prevent surface defects resulting from bonding between single filaments at an early stage of carbonization and to obtain reinforcing carbon fiber having a few inner voids, high strength and high modules of elasticity by subjecting acrylic yarn to flameproofing treatment and carbonizing the fiber at specific temperature under reduced pressure while drawing. CONSTITUTION:Acrylic fiber is heated in an oxidizing atmosphere to carry out flameproofing treatment and then carbonized at 300-1,000 deg.C preferably 300-550 deg.C under =3%, preferably >=10% to give the aimed fiber.

    Abstract: PURPOSE:To raise productivity and to obtain the title fibers in high yield by providing a base material as a cathode with electric charge in an aqueous solution containing metallic ion, supplying the base material with a metallic catalyst and thermally decomposing a hydrocarbon gas by using the base material. CONSTITUTION:A base material such as graphite board or carbon fiber as a cathode is provided with electric charge in an aqueous solution containing ion of metal such as iron or nickel and the base material is supplied with a metallic catalyst. Then the base material is used and a hydrocarbon gas such as methane, benzene or ethane is thermally decomposed by using a hydrogen gas as a carrier gas at 700-1,500 deg.C to give the aimed fibers.

    Abstract: PURPOSE:To improve both coherency in winding and productivity and simultaneously prevent fluffing or shoulder collapse, by forming carbon fibers from precursors thereof, then applying and keeping water with a specific electric conductivity or below and winding the resultant carbon fibers. CONSTITUTION:Precursor fibers consisting of acrylic fibers for carbon fibers are carbonized to form the carbon fibers, which are then wound in a state in which water (especially preferably distilled water or ion exchange water) having

    Abstract: PROBLEM TO BE SOLVED: To provide a carbon fiber bundle excellent in higher-order processability and adhesiveness with a matrix resin. SOLUTION: This carbon fiber bundle is constituted by adding a polyfunctional aliphatic compound having >=2 epoxy groups in a molecule onto the surface of a carbon fiber bundle and covering the aforesaid surface with a composition comprising (A) an epoxy resin, (B) a condensation product of an alkylene oxide adduct with an unsaturated dibasic acid, and (c) an adduct of a phenol with an alkylene oxide.

    Abstract: PROBLEM TO BE SOLVED: To provide a graphite fiber having excellent adhesivity to a matrix resin and excellent in a compression strength at 0 deg.C, a polyacrylonitrile fiber suitably used as the raw material and a method for manufacturing the polyacrylonitrile fiber. SOLUTION: The method for manufacturing a polyacrylonitrile fiber comprises subjecting a polyacrylonitrile-based copolymer to wet spinning or dry-wet spinning, washing the resultant fiber with water, subsequently applying a phenolic resin on the fiber, and further making the treated fiber compact by drying.
