Abstract: PURPOSE:To enable to obtain a steering wheel core material with sufficient torsional rigidity by a method wherein the rotating shaft of a take up unit is directed in nearly the same direction as the direction, in which fiber bundle is supplied. CONSTITUTION:In order to form a steering wheel core material, the spoke parts 8 are formed by winding resin-impregnated fiber bundle 5 from one notched part 7 of a take-up jig 1 to a boss piece 4 while laminating a ring part 6. At that time, before winding the bundle to the boss piece, a rotating shaft 3 is turned by 90 deg. so as to direct the rotating shaft 3 in the same direction as the direction, in which the fiber bundle 5 is supplied in order to twist the fiber bundle 5. After the fiber bundle 5 is twisted in the above-mentioned manners, the rotating shaft 3 is again returned to its original direction to form the spoke part 8. By repeating the operation as mentioned above, the steering wheel core material made of fiber bundle, to the spoke part of which twisting is applied, is laminated.

Abstract: PURPOSE:To produce the reinforced plastic structure excellent in the characteristics of uniformity and strength, etc. at high productivity by applying ultrasonic vibration to the bundle of continuous fiber being impregnated with resin. CONSTITUTION:When the bundle 2 of continuous fibers passes through the inside of resin 8 in a coating tank, the ultrasonic vibration from an ultrasonic vibrator 10 is applied onto the bundle together with the resin 8. Consequently, the wetting property of the continuous fiber to the resin 8 is improved and the bubbles having been mixed in the bundle 2 at its dipping are raised smoothly by its buoyancy and removed in open air. Therefore, the structured article 13 formed with a resin impregnated fiber bundle 14 has almost no bubble, large fiber amount (Vf) and a uniform and fine structure with high strength. Because the continuous fiber is caused to have specially good wetting property to the resin 8 by ultrasonic vibration, the bundle 2 of the continuous fiber is easily impregnated with the resin 8.

Abstract: PURPOSE: To enable to twist continuous fiber bundle by a method wherein a resin impregnating tank is rotated at the desired winding position of a molding tool.
CONSTITUTION: A bobbin 2, onto which continuous fiber bundle is wound, is attached in a resin impregnating tank 1, which can be rotated by means of a rotating shaft 4 installed on a rotating table 3. The continuous fiber bundle is drawn out of the liquid resin 6 in the resin impregnating tank 1, squeezed through a die 7 and wound onto a take-up unit. During manufacturing a structural body, when the fiber bundle 5 reaches a hook 9', the rotation of a main column 8 is stopped and at the same time the resin impregnating tank 1 is rotated by means of the rotating shaft 4, resulting in twisting the fiber bundle 5. Due to the twisting of the fiber bundle through the rotation of the whole resin impregnating tank, the twisting operation can be performed very easily.

Abstract: PURPOSE: To obtain a fibrous resin-structural material which is superior in mechanical characteristics, by a method wherein a structural material is formed by taking up a continuous long fiber impregnated with resin and heating and curing are made to perform after a jig has been made to revolve.
CONSTITUTION: As for a continuous long fiber and synthetic resin which is made to impregnate into the fiber, articles to be used normally for an FRP (fiber-reinforced resin) product are used. A continuous high tensile glass fiber, for example, which has been made to impregnate with unsaturated polyester resin is taken up on a take-up jig 1 and a three dimensional structural material 2 is formed. The take-up jig 1 is fitted to a rotating shaft 4 of a centrifugal separator 3 and made to rotate in the direction of an arrow. The resin removed from the structural material 2 through centrifugal force is recovered through an unloading outlet 5 for reuse. Then the structural material 2 is made to heat and cure with a heating device. Mechanical characteristics of the product is improved as the excessive resin is removed from the structural material formed on the take-up jig through centrifugal force, it does not happen that the fiber is damaged or made to break and as the fibers are filled far thicker and voids which have been contained among fibers are reduced.
