摘要： PURPOSE: To obtain fiber reinforced resin construction used for steering wheel having superior vibration resistance and high strength by constituting the forked part of said fiber reinforced resin construction as that the resin immersed fibers are bundled tightly and frees from any clearance.
CONSTITUTION: A mold 5 from which the ring part of a steering wheel is shaped has a winding groove 6 formed through the entire circumference thereof. A notch 7 which communicates the winding groove 6 with the central part of the mold is formed at the internal peripheral part of the mold 5. Pins 8 on which fiber bundles are wound up are arranged in said notch 7. After continuous fibers such as carbon fibers or the like are immersed in epoxy resin or the similar, the resin immersed fiber bundle of the continuous fibers is wound up to make layers along the winding groove 6. A ring part is thus made up. A forked part from which spoke extends is formed at the notch part 7 by arranging the fiber bundles tightly by use of the pins 8. The forked part of the spoke part from the ring part will therefore be prevented from producing a clearance.

摘要： PURPOSE:To obtain a light wt. steering wheel having not only vibration resistance but also high strength and excellent torsional rigidity, by orienting a resin impregnated fiber bundle comprising continuous fibers in the axial direction of each part to form a skeketal and subsequently winding the resin impregnated fiber bundle around the skeletal at a predetermined angle to the axial direction of each part. CONSTITUTION:A line of a resin impregnated fiber bundle comprising continuous fibers are wound around the mold of a steering wheel predetermined times to form a skeletal 11 and a separate resin impregnated fiber bundle 12 comprising continuous fibers is wound around the skeletal 11 at a proper angle theta to the axial direction of a spoke part to form a steering wheel made of continuous fiber FRP. It is desirable to select the angle theta in a range of 30-60 deg.. By this constitution, the torsional rigidity of the spoke part is markedly enhanced as compared with such a case that the resin impregnated fiber bundle comprising continuous fiber is oriented only to the axial direction (direction wherein the angle theta is 0 deg.) of the spoke part.

摘要： PURPOSE:To manufacture an FRP pipe having high quality by a method wherein a fiber reinforced resin is laminated on a mandrel and thermoset, a resin film is drawn in the axial direction and a clearance is formed between the mandrel and a thermosetting resin layer. CONSTITUTION:A resin film 2 is applied on the circumferential surface of a square-shaped mandrel 1, and a fiber reinforced resin layer 3 is shaped on the resin film 2. A cured resin layer 3' is formed on the mandrel 1 through the resin film 2 through thermosetting treatment, and the resin film 2 is drawn in the axial direction as shown in the arrow A. When stress in the direction of clamping of the mandrel 1 does not remain in the cured resin layer 3', the resin film 2 is drawn without orientation because frictional force working between the mandrel 1 and the cured resin layer 3' is small: when stress remains, the resin film 2 is oriented and drawn while a section thereof is shrunk. Accordingly, a clearance 4 is shaped between the mandrel 1 and the cured resin layer 3', and the mandrel 1 is drawn out finally, thus obtaining an FRP pipe having a predetermined shape.

摘要： PURPOSE:To manufacture an FRP pipe, which is excellent in quality and low in cost, by winding roving impregnated with a thermosetting resin on a product- shaped mold formed by injecting a gas to a flexible tube member and thermosetting the roving. CONSTITUTION:A product-shaped mold 1 consists of a flexible tube member, which can be expanded and shrunk by injecting and discharging a gas and has non-tackiness and heat resistance, and is expanded and is formed to a predetermined shape through injection of air to the inside from an air injection hole 1a shaped to one end of the tube member. On the other hand, a fiber reinforced resin layer 2 is formed by winding roving composed of carbon fiber or glass fiber impregnated with a thermosetting resin on the outer circumferential surface of the mold 1 by using a guide jig. The mold 1 and the resin layer 2 are heated integrally, and the resin layer 2 is cured. When air is discharged from the mold 1, the mold 1 is shrunk and a clearance is shaped between the mold 1 and a cured resin layer 2', and the shunk tube member is drawn out, thus obtaining an FRP pipe having a prescribed shape.

摘要： PURPOSE:To obtain a fiber reinforced resin structure having air bubbles present therein so as to be reduced and made fine as possible and posessing sufficient strength, by preparing a long fiber reinforced resin structure under an adjusted atmosphere. CONSTITUTION:An air-tight container 9 is held under a reduced pressure atmosphere. A raw yarn 4 comprising a carbon fiber is immersed in an impregnation apparatus 7 before wound up by a wind-up jig 8. Because the atmosphere of the apparatus is under reduced pressure, moisture or air in the fiber is preliminarily removed and a resin solution is rapidly penetrated into the fiber and adhered thereto. The wind-up jig 8 winds up the raw yarn 4 while reciprocates in left and right directions by the guidance of a traverse guide 10 and, after the raw yarn 4 is laminated so as to reach a desired thickness, internal pressure of the air-tight container 9 is returned to atmospheric one. Whereupon, the resin on the surface of the laminate is pressurized and sufficiently penetrated into said laminate. Even if air slightly remains at the time of lamination, said air is pressed by the penetrating resin and the size of air bubbles becomes fine. Next, the laminate is heated under atmospheric pressure or forcible pressure and cured. By this method, a structural material having high rigidity and receiving the reduced effect of air bubbles is obtained.

摘要： PURPOSE:To facilitate production by using a distributor distributing a continuous, long fiber reinforcement in the circumferential direction of a rim section and the radial direction of a spoke section at the intersection of the rim section and the spoke section of a steering wheel. CONSTITUTION:A distributor 9 made of metal such as aluminum or resin such as unsaturated polyester has a straight groove 10 for distributing to a rim section and a circumferential groove 11 for distributing to a spoke section when winding a continuous, long fiber reinforcement made of high-tension glass fibers, and it is coupled with the notched section 3 of a winding jig 1. A core material formed by winding a desired quantity of the long fiber reinforcement shown by a dashed line is removed from the winding jig 1 and transferred to a steering mold, and the core material is further coated with unsaturated polyester resin, polypropylene resin, etc. and is heated and pressurized under the predetermined temperature and pressure to obtain a steering wheel 12.
