    Abstract: PURPOSE:To manufacture easily FRP-made reinforced bars having a large holing power over concrete or the like. CONSTITUTION:FRP made projected parts, which are 0.05 to 1mm high on average and extend in the longitudinal and lateral directions of a flat bar core body, are installed to a plate side of an FRP-made flat bar core body, thereby forming reinforced bars. The reinforced bars are manufactured by using uncured thermosetting resin for the plate side of the FRP-made bar-shaped plate core body and pasting the FRP-made meshed body whose leg size ranges from 0.05 to 1mm in such a fashion that the leg may conform to the longitudinal and lateral directions of the plane core body and then curing the thermosetting resin and integrating the meshed body with the plate core body.

    Abstract: PURPOSE:To obtain the subject lightweight product, having corrosion resistance, good in operating efficiency and suitable for building materials or civil engineering by impregnating fiber bundles with an epoxy resin in a specific proportion, semicuring the resin, twisting the resultant fiber-reinforced composite element wires and then thermosetting the resin. CONSTITUTION:Fiber bundles (generally fiber bundles of carbon fiber, aramid fiber or glass fiber) are initially impregnated with an epoxy resin so as to provide 40-70wt.% fiber content and then preferably semicured by a method for treatment at 80-120 deg.C for 1-5min. The resultant plural fiber-reinforced composite element wires having 1-5 mm diameter are subsequently twisted to afford a fiber-reinforced composite material, which is then heat-treated preferably at 150-180 deg.C for 2-5min and cured to provide the objective product. Furthermore, the diameter of the product is preferably 3-50mm from the viewpoint of use as a substitute wire rope in applications of civil engineering and construction. The number of twists of the rope is preferably 1-10 turns/m in aspects of shape retaining properties, etc.

    Abstract: PURPOSE:To provide the subject device preventing the invasion of outer air, etc., from inlets and outlets for a fiber to be treated for energy saving and further preventing the contamination of tars by sealing the inlets and outlets due to contact between the fiber and a heat-resistant fiber. CONSTITUTION:A heat-resistant fiber (e.g. fluorofiber) 7 resisting to a flame- resistant treatment temperature of 300-400 deg.C and not giving any damage to a fiber to be treated when rubbed with the fiber is disposed on the inlet or outlet (sealing portion) 5 of a flame-resistant treatment oven 1 of a heat treatment device for preparing carbon fiber to provide the objective device. A fiber 2 to be treated, such as a filament of phenolic organic polymer, is fed into a flame-resistant treatment oven 1, brought into contact with carbon particles, etc., and subsequently passed through an outlet in a sealing state contacting with a heat-resistant fiber 7.

    Abstract: PURPOSE:To attain further improvement in the strength and elastic modulus of a carbon fiber and to shorten the overall treatment time of the process for the production of a carbon fiber by carrying out the drawing and flame- resisting treatment of a precursor fiber in a fluidized layer under a specific condition. CONSTITUTION:A precursor fiber is drawn in a fluidized layer under a condition to satisfy the formulas DR>=1.1, 0.7

    Abstract: PURPOSE:To obtain a graphite fiber, having respective specific torsional elastic modulus and compressive elastic modulus and improved compressive strength in using a plastic as a matrix and capable of providing composite materials suitable as lightweight structural materials by using a plastic as a matrix. CONSTITUTION:For example, an acrylonitrile based polymer (preferably containing ); Ef is tensile elastic modulus (t/mm )]. The above-mentioned graphite fibers and a plastic are used to afford a composite material suitable as gold shafts, etc.
