のである。(Example) In the first example, as shown in Fig. 1.2, prepreg (2) made of high-strength fibers such as carbon fibers impregnated with synthetic resin is wound around the core (A), and the rod body ( 1), a 5 k tape (3) made of polyamide resin with excellent heat resistance and impact resistance is placed around the outer circumference of the rod body (1).
The rod body (1) is tightly bound by winding the rod body (1) in a spiral shape with a tensile force of approximately After that, it is heated in a heating furnace for 140 minutes.
The core metal (A) is fired after firing at a temperature of around 100°C.

を高めることができるのである。Therefore, according to the present invention, even if the rod body (1) is made of carbon fiber prepreg, which has low impact resistance and is brittle, as in the case of a thick fishing rod, the outer periphery of the rod body (1) The fishing rod has a reinforcing layer (4) made of a polyamide resin with excellent impact resistance, and this reinforcing layer (4) serves as a strength member against impact, so it is possible to increase the impact strength of the fishing rod. This can prevent damage caused by impact. In other words, it is possible to prevent cracks from occurring due to impact forces such as when the product is dropped on the ground or hits a rocky area, and its durability can be increased.

るのである。Further, the tape (3) made of the polyamide resin has 1
Even at temperatures around 40°C, there is little decrease in tensile force, that is, there is little elongation due to heat, and sufficient tensile force can be obtained.
When the tape (3) is bound with a certain tensile force and then fired at a temperature of around 140°C, the elongation of the tape (3) due to the firing heat is small and the tape (3) is maintained at the initial tensile force of about 5 kg. In other words, since the rod body (1) can be tied with sufficient tension, the uniformity of the rod body can be improved.
This prevents voids and dents from forming on the surface layer of the rod body. Therefore, the tensile strength of the fishing rod can be increased.

る。That is, conventionally, a polyester tape is spirally wound around the outer peripheral surface of a prepreg rod body to bind the rod body, and firing is performed in this bound state. Even if a tensile force of about 5 kg is obtained at a high temperature of around 140°C, the tape stretches and the tensile force decreases to around 2 to 3 kg. Therefore, when firing at around 140°C, the rod body It is not possible to bind the rod sufficiently tightly, and the uniformity of the rod body becomes poor.
As a result, it is not possible to completely remove the air bubbles contained inside the rod body or between the rod body and the core metal, and after firing, many voids and dents are likely to be formed on the surface layer of the rod body, resulting in tensile stress. There is a decrease in the strength, and this problem also occurs when the amount of impregnation of the synthetic resin is reduced - Intra-shell impregnation N (35-40vt%)
This phenomenon becomes more noticeable when the rod body (1) is made of prepreg, which has a higher tensile strength by reducing the ratio of high-strength fibers to, for example, 33 vt% or less. By tightly binding the rod body (1) using tape (3) made of resin, it is possible to form a fishing rod with no voids or dents on the surface layer.

前記ボイド、凹みのない釣竿を形成できるのである。In addition to wrapping the tape (3) made of polyamide resin closely around the edges as described above, it is also possible to wrap the edges overlapping each other as shown in Figure 3. Also, it is possible to form a fishing rod without the above-mentioned voids and dents.

きるのである。In the second embodiment, the rod body (1) is formed of prepreg with a reduced amount of synthetic resin impregnated, while the back side of the tape (3) is physically or chemically treated as shown in Fig. 4. The tape (3) has a rough surface to enhance the adhesion of the tape (3) to the rod body (1) and increase the bonding force. In this case, the impact strength of the fishing rod can be further increased. It is.

防止できるのである。In the third embodiment, the rod body (1) is formed of prepreg with a reduced amount of synthetic resin impregnated, while the back surface of the tape (3) is made rough as described above, and this rough surface is The back surface of the tape (3) was coated with a synthetic resin that adhered to or was compatible with the synthetic resin of the prepreg (2), as shown in FIG. By doing so, it is possible to improve the adhesion of the tape (3) to the rod body (1) and increase its bonding force, and also because the amount of synthetic resin impregnated in the prepreg (2) is small, the voids, Even in a state where dents are easily formed, the synthetic resin coated on the tape (3) can be brought into close contact with or be compatible with the synthetic resin of the rod body (1) during the firing, and the rod body (1) can be easily formed. This can prevent voids and dents from forming on the surface layer.

ある。Further, the fishing rods formed as in the first to third embodiments are roughened by puff polishing or the like and then painted, as in the conventional case, and the outer periphery of the rod body (1) is coated with a coating. Since there is a reinforcing layer (4) made of polyamide resin with excellent impact resistance, it is possible to prevent the strength from decreasing due to the above-mentioned puff polishing. ), it is possible to simplify the work process and reduce costs.
