この発明は、フィラメントワインディング法による繊維
強化プラスチックス製円筒体の製造方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a cylindrical body made of fiber reinforced plastics by a filament winding method.
繊維強化プラスチックス（以下ＦＲＰという）によって
製作した円筒体は、ゴルフクラブ、釣竿等のスポーツ用
品をはじめとして宇宙科学や航空機の分野等種々の用途
への適用化が検討されている。Cylindrical bodies made of fiber-reinforced plastics (hereinafter referred to as FRP) are being considered for application to various uses such as sports equipment such as golf clubs and fishing rods, as well as the fields of space science and aircraft.
ＦＲＰ製円周円筒体作においては、ＦＲＰの強度メンバ
ーである補強材の寄与度が最も高い方法である連続繊維
を用いたフィラメントワインディング法（以下ＦＷ法と
いう）が多々使用されてぃる。In the production of circumferential cylinders made of FRP, the filament winding method using continuous fibers (hereinafter referred to as the FW method) is often used, which is the method in which the contribution of the reinforcing material, which is the strength member of FRP, is the highest.
しかし、ＦＷ法を用いて円筒体を製作する場合繊維の巻
付角（巻付繊維と製品の長手方向のはさみ角）が低くな
ると締付は力が低下するため、繊維含有率が上がらず、
高角巻きの場合に比べて性能が劣ることが多い。また巻
付繊維も滑り易いため角度も乱れがちとなる。特にこの
傾向は０度付近の巻付角において著しい。However, when manufacturing a cylindrical body using the FW method, if the wrapping angle of the fibers (the angle between the wrapped fibers and the longitudinal direction of the product) decreases, the tightening force will decrease, so the fiber content will not increase.
The performance is often inferior to that of high-angle winding. Furthermore, since the wrapped fibers are also slippery, the angle tends to be irregular. This tendency is particularly noticeable at wrap angles around 0 degrees.
この発明の目的は、ゴルフクラブ等軸方向の剛性を要求

することにある。The purpose of this invention is to solve the above-mentioned problems for products that require rigidity in the axial direction, such as golf clubs, by using prepreg, especially wet prepreg, and by using the FW method to extremely easily and highly accurately wrap low angle windings. The purpose is to enable 0 degree winding.

したものである。In order to solve the above-mentioned problems, the present invention provides a molding method in which a disk forming jig is slidably inserted into the mandrel protruding from both ends of the mandrel, and the forming jig is provided with means for sliding in the axial direction. Using a device, resin-impregnated fibers are wound around the mandrel and the molding jig at a required winding angle in the axial direction to form a prepreg, and after the prepreg is fixed to the molding jig, the sliding means is operated to mold it. The jig is moved in a direction away from the mandrel, and then resin-impregnated fibers are wrapped around the prepreg in the circumferential direction at a required wrapping angle, thereby forming a circumferential cylindrical body made of FRP.

。As shown in FIGS. 1 and 2, the molding device used to carry out this invention includes a mandrel 1 with a disk-shaped molding jig 3 slidably inserted into a mandrel 2 protruding from both ends of the mandrel 1. As a sliding means for the forming jig 3, a screw hole 4 penetrating in the axial direction is provided, a bolt 5 is screwed into the screw hole 4, and its tip is brought into contact with the end surface of the mandrel 1. When the bolt 5 is turned, the forming jig 3 slides on the mandrel 2.
また、成形治具３の外周面には溝６が設けられている。Further, a groove 6 is provided on the outer peripheral surface of the forming jig 3.

A part of the prepreg 8 is dropped into the groove 6 of the molding jig 3 and fixed by tightening it with a binding device 9 such as a rubber string from around the prepreg 8.
その後、各ボルト５を回動操作して成形治具３をマンド

品に仕上げる。With the prepreg 8 under tension as described above, a reinforcing layer 10 with a high winding angle is formed as the next layer by the FW method on top of the prepreg 8 with a required winding angle. The wrapping angle in this case can be freely set within a range that does not cause slippage, and is set to, for example, 45 degrees or 90 degrees. After the reinforcement @10 is formed in this manner, both ends are cut to complete a cylindrical product.
