熱していく段階での樹脂の流動性が悪い。However, in the above manufacturing method, since the laminated body is bent and the winding end sides are opposed to each other to form a tubular shape, there is a large change in the cross section in the longitudinal direction. When the fishing rod is formed, the winding end sides do not match and it is difficult to form the fishing rod. In addition, since the reinforced fiber woven fabric is a fishing rod with a polyethylene resin layer interposed between the reinforced fiber woven fabric and the thermoplastic resin plate, the amount of resin increases, the fiber ratio decreases, the strength and elasticity decrease, and the weight increases. Further, unlike thermosetting resins, thermoplastic resins are solidified at room temperature, and their melting points are generally considerably higher than the curing heating temperature of thermosetting resins, so at the stage of heating during fishing rod forming work, Poor fluidity of resin.

共に剥離が発生する等の問題がある。Therefore, when the ratio of the reinforcing fibers is simply increased in order to improve the strength and elasticity of the fishing rod or to reduce the weight thereof, the resin does not spread between the reinforcing fibers due to the poor fluidity of the resin, and bubbles are formed inside the laminate. The strength of the fishing rod is reduced and the fibers are exposed from the surface of the fishing rod, causing unevenness on the surface, resulting in a rough surface and numerous micropores, resulting in poor appearance and the surface cannot be decorated. Due to the presence of the micropores, there is a problem that poor adhesion and progress of corrosion occur, and peeling occurs with time even after decoration.

する。Further, a fiber-reinforced thermoplastic resin sheet having a volume ratio of reinforcing fibers higher than that of a thermoplastic resin is wound around the outer periphery of the irregular-shape forming inner mold, and at least the surface is provided with woven or braided reinforcing fibers. A main body layer corresponding portion is formed, and a thermoplastic resin sheet is wound around the main body layer corresponding portion to form a resin layer corresponding portion thinner than the main body layer corresponding portion.

Since the resin layer on the outside is thin, the fishing rod is lightweight and has high strength and high elasticity. Furthermore, since the outside of the main body layer is a smooth thermoplastic resin layer filling the woven or braided microscopic depressions on the surface of the main body layer, a fishing rod with high appearance and high surface quality is provided.

Since the main body layer can be formed along the irregular shape and the ratio of the reinforcing fibers is high, the main body layer is light and has high strength and high elasticity. The thin resin layer corresponding portion on the outer side is formed by a thermoplastic resin sheet, and the profile-forming outer die is covered and heated while applying pressure to the die, so that air bubbles are generated in the body layer corresponding portion due to the pressure. However, it can be extruded and formed into a high-strength fishing rod. On the other hand, since the ratio of the reinforcing fibers is large, the fibers are exposed on the surface of the main body layer and unevenness may be generated on the surface to cause roughness or many fine holes, but this is heated by the presence of the thermoplastic resin sheet. When melted, the fluidity is improved to fill the irregularities and the micropores, and the inner surface of the outer die is smooth, so that the outer surface of the resin layer is smooth, and a high-quality fishing rod is provided.

For example, in the case of PEEK, heat it to 360 ° C to 400 ° C,
The heating time is preferably 10 minutes to 30 minutes. Also, PA, PE
Since T, PC and PP can be molded at a low molding temperature of 280 ° C. or lower and the resin is easily fluidized, a thin and thick fishing rod can be molded at low cost. However, since the amount of the thermoplastic resin is small, the fibers are likely to be exposed on the surface of the main body layer 18 and small irregularities are likely to occur, so that the thin resin layer 20 is formed.

きる。In this case, the surface of the corresponding portion 20 'of the resin layer 20 is covered with the smooth outer shape-forming mold 24 having an inner surface and is a thermoplastic resin layer, so that the resin flow is easy and The surface of the layer corresponding portion 20 'is formed to be smooth, and it is also possible to fill the micro recesses of the braid or the woven cloth on the surface of the main body layer corresponding portion 18'. Further, since the main body layer corresponding portion 18 'and the like are sandwiched between the inner and outer molds and a large pressure is applied, the bubbles generated at the time of heating formation are pushed out to the outside. In order to protect the fishing rod thus formed, a protective layer such as urethane coating may be applied on the resin layer 20, and the resin layer 20 of the present invention is in a state excluding such a protective layer and a decorative layer. It forms the epidermis of the rod body. Since the skin surface is smooth, a layer for decoration or the like can be easily formed thereon.

と成る。Next, after cooling, the irregular-shape forming outer mold 24 is released, and then the pressure is lowered to take out the pressing force adjusting member 32 and the molded base rod 10 is taken out. As described above, the base rod has a smooth surface and the internal main body layer has a large proportion of reinforcing fibers, so that the rod is lightweight and has high strength and elasticity. Furthermore, for example, thermoplastic PEEK
Has an energy release rate of 6 times or more and a fracture strain of 10 times or more higher than thermosetting epoxy resin.
Since EEK is a material that is ductile and has high toughness, when PEEK is used as the thermoplastic resin, the interfacial adhesiveness with the reinforcing fiber and the resin elastic modulus are high, and the fishing rod 10 having a higher function is used.
