れている。(Prior Art) Conventionally, shafts made of fiber reinforced plastics (hereinafter abbreviated as FRP) have been made using various types of reinforcing fibers such as carbon fiber, glass fiber, aramid fiber, boron fiber, alumina fiber, and silicon carbide fiber, either alone or as reinforcing fibers. used in combination. On the other hand, as the matrix resin, epoxy resin is mainly used, but thermosetting resins such as unsaturated polyester resin and phenol resin are also used. The performance required for matrix resin is as follows:
It is required that it be easily impregnated into fibers, have good interfacial wettability, and have high adhesive strength. Furthermore, it must have greater elongation than reinforcing fibers to fully demonstrate the characteristics of the fibers. Additionally, there is a demand for materials with high toughness and impact resistance.

防止した釣竿等の管状体が開示されている。JP-A-50-72731 discloses a golf club shaft with improved impact resistance by embedding a thermoplastic resin in the hollow part of the shaft, and JP-A-54-45383 discloses a thermoplastic resin film as an intermediate layer of thermosetting prepreg. A tubular body, such as a fishing rod, in which a sheet is inserted to prevent warping is disclosed.

温ボックス中で130℃2hr程度の条件で硬化する。In addition, the currently common method for manufacturing FRP shafts is to wind UD receipt cloth prepreg with an epoxy resin matrix around a mandrel, or to impregnate rovings of various fibers with epoxy resin and perform filament winding. There is a way to do it. Both were then wrapped with wrapping tape and cured in a thermostatic box at 130° C. for about 2 hours.
硬化の完了したバイブはラッピングテープを除去し、研

及ばない。(Problem to be Solved by the Invention) However, with thermosetting resins, wettability and adhesiveness can be improved by sizing the lll1i fibers.
Although impregnating properties can be improved by heating the resin, it is not as good as thermoplastic resins in terms of elongation and toughness.

になる。Further, a large impact force is applied to the golf club shaft when hitting a ball. For this reason, reinforcing materials are inserted in some areas to prevent the shaft from breaking due to stress concentration, but while these reinforcing materials strengthen the shaft, they also make some parts of the shaft stiffer, which has a negative effect on bending. In other words, the degree of freedom in design is hindered in designing the optimal bend of the shaft for hitting the ball far, which is the most appealing aspect of golf.

トの特性上好ましくない。The golf club shaft shown in Japanese Patent Application Laid-Open No. 50-72731 is Akumar! A thermoplastic resin is used for a part of the shaft made of a thermosetting resin, and this method adds unnecessary weight to the shaft, which is not preferable in terms of the characteristics of the shaft.

If Brib I Nog is to be stored and used for a long period of time, it is necessary to store it under the following conditions: The tack and drape properties of bunobreg are easily affected by temperature, even if it is stored for less than -,〉-months at room temperature, so careful storage is required and storage facilities are essential.Furthermore,
The 2 hours required for middle and bottom curing of the process is extremely long, and it is desired to shorten this time.
