SOLUTION: A winding package 1 of a carbon fiber bundle Y, the carbon fiber bundle Y is arranged by a draw free rotation roller 2. Next, the bundle Y is arranged through a separation comb 3 and supplied to an inversion preventing device 5. A heating means 4 is installed upstream from the device 5, and the bundle Y is heated. After that, the bundle Y is passed through the device 5 consisting of a roller having projections on its surface and a free rotation roller 6 to prevent inversion. Subsequently, then bundle Y is passed through an opening apparatus 7 and introduced into an impregnation apparatus 11. The opening apparatus 7 is constituted so that the carbon fiber bundle Y supplied through an introduction free rotation roller 7a passes on a group of rollers while being bent at a prescribed angle to be opened and discharged through an opening apparatus exit free rotation roller 7d.

Abstract: An epoxy resin composition suitable as a matrix resin for fiber reinforcement; and a yarn prepreg which has an excellent high-order processability by virtue of suitable unwindability and drapeability and a high degree of development of tensile strength and reinforced fiber strength after the curing of the epoxy resin. The yarn prepreg is characterized in that the weight content Wf (%) of fiber bundles, the number F of filaments in the fiber bundles, and the prepreg width d (mm) satisfy the following relationships: (1) 50 ≤ Wf ≤ 80; (2) 20000 ≤ F ≤ 100000; (3) F/8000 ≤ d ≤ F/2400. The epoxy resin composition comprises the following components: [A] an epoxy resin blend having an epoxy equivalent of 210 to 370, comprising a mono- or difunctional epoxy resin and a tri- or higher polyfunctional epoxy resin in respective particular amounts; [B] fine particles which contain a rubber component and are insoluble in the epoxy resins; and [C] a curing agent.

Abstract: PROBLEM TO BE SOLVED: To obtain a fly wheel hard to generate a crack even if rotated at a high speed and excellent in durability by winding an epoxy resin prepreg containing reinforcing fibers arranged in one direction so that reinforcing fibers are oriented in a peripheral direction to constitute fiber reinforced plastic and setting the voids thereof to a specific value or less. SOLUTION: In a wet method, an expoxy resin compsn. is uniformly mixed with a solvent having epoxy resin dissolving capacity such as methyl ethyl ketone and, thereafter, reinforcing fibers arranged in one direction are immersed in the resulting soln. so that fiber content becomes a desired value to be allowed to run and the solvent is volatilized from the resin impregnated reinforcing fibers in a hot air dryer. In a hot-melt method, the uniformly kneaded resin compsn. is applied to a releasable film coated with silicone or the like to form a resin film which is, in turn, held between at least one surface of reinforcing fibers arranged in one direction to be heated and pressed to impregnate the fibers with the resin. Voids are made hard to generate in fiber reinforced plastic and void vol. can be reduced to 3% or less.

Abstract: PURPOSE:To improve the tensile strength of a carbon fiber containing fine particles for improving the performance of the fiber or imparting additional function to the fiber. CONSTITUTION:The objective carbon fiber contains fine particles exclusively in the inner layer of single fiber. The fine particle-containing carbon fiber has high tensile strength and is hardly producible by conventional process. The fiber has high tensile strength as well as improved performance or imparted additional function by the mixing of fine particles. Since the carbon fiber has high tensile strength and excellent elastic modulus, compressive strength, electrical conductivity, electric wave shielding property or heat-resistance, it is useful as a reinforcing fiber for a composite material containing thermosetting resin, thermoplastic resin, ceramic, metal, etc., as a matrix, concretely, aircraft such as supersonic flying object, space articles such as rocket and truss, sports goods such as fishing rod and golf shaft, electric wave shielding material and heat- resistant member.
