本発明は、FRP製ホイールの製造方法に関し、特に強

る方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing an FRP wheel, and particularly to a method for efficiently mass-producing wheels with excellent strength and rigidity.
(従来の技術)
一般に自動車用タイヤホイールは、アルミ合金等で製造
されているが、より軽量化を指向するためにFRP製の
ホイールが実用化されつつある。(Prior Art) Automobile tires and wheels are generally manufactured from aluminum alloy, etc., but wheels made from FRP are being put into practical use in order to aim for further weight reduction.

ずと短繊維の使用量が増加して成形品の重量が大となり
、アルミ合金製等のものに比べてメリットがなくなる。By the way, as a conventional method for manufacturing FRP wheels, there is a method of press-molding short fibers such as carbon fiber impregnated with a thermosetting resin, but the so-called chopped fiber reinforced plastic molding obtained by this method Since the physical properties of the product are isotropic, it is difficult to obtain sufficient strength and rigidity. However, if you try to obtain sufficient strength and rigidity, the amount of short fibers used will naturally increase, which will increase the weight of the molded product, and there will be no advantage compared to products made of aluminum alloy or the like.

インディング成形法が提案されている。Therefore, as a method to ensure the strength and rigidity of a molded product, for example, as disclosed in Japanese Patent No. 56-120316, a filament coated with a thermosetting resin is wound around the surface of a mandrel to achieve a predetermined thickness. A filament winding molding method has been proposed in which a molded product is obtained by forming a winding layer, dividing the winding layer and separating it from a mandrel, and curing each separated winding layer by applying heat and pressure.

う問題があつた。(Problem to be Solved by the Invention) However, in the conventional manufacturing method described above, since tension is applied to the filament, it is possible to obtain a molded product with sufficient strength and rigidity, but on the other hand, it is difficult to form a molded product on one mandrel. Since this method involves dividing and separating the winding layer into two, there was a problem in that a large number of molded products could not be obtained at the same time.

。On the other hand, in Japanese Patent Application No. 59-208980, the present applicant used a mandrel having a shape in which the outer surfaces of two members matching the concave shapes on both sides of the wheel were joined together, and the surface of the mandrel was coated with thermosetting resin. A filament winding molding method in which a resin-coated filament is wound to form a winding layer, and after heating and hardening, it is separated at the above-mentioned joint and separated from the mandrel, and each separated winding layer is fixed back to back and assembled to form a wheel. is suggesting. However, this method also has the same problems as the conventional example above in terms of productivity, and because the separated molded products are assembled back-to-back and assembled into a wheel, the assembly process takes time and productivity is improved. It is difficult to do so, and there are also problems in securing the bonding strength.

After that, adjacent winding layers are fixed to each other by heating and curing, and then each winding layer is divided and separated continuously to efficiently mass-produce FRP wheels with excellent bonding strength in a short time. It is in.
