The purpose is to efficiently manufacture fishing rods.

となる欠陥がある。Conventional technology Hexagonal fishing rods and fishing rods with an oval cross section are known to have good directional stability during bending, but in order to manufacture such fishing rods with current fiber-reinforced resins, it is necessary to wrap them around a core metal. The prepreg is placed in an outer mold with a non-circular cross section and the prepreg layer is forcibly deformed into the shape of the cavity of the outer mold and pressure molded. Movement may cause wrinkles or openings in the fibers, creating unevenness on the surface of the tube after curing, reducing the strength of the tube, and reducing the coefficient of thermal expansion of the outer mold and prepreg during thermosetting. Because of this difference, internal distortion occurs in the prepreg due to shrinkage of the outer diameter during cooling, resulting in defects that cause bending.

するものである。Structure of the Invention The present invention improves these defects and manufactures a tubular fishing rod with a non-circular cross section.A tape is wound around the outer circumferential surface of a prepreg wound around a core metal, and then this is shaped into an elliptical cross section. The gist of this method is to put it into a non-circular outer mold such as a polygon, pressurize it, mold it into a non-circular cross section, heat harden it, and remove the tape and core metal.

うな断面楕円形に硬化成型される。 The details of the present invention will be explained with reference to the drawings of the embodiments. After a prepreg 2 is wound around a core metal 1 in the usual manner, a tape 3 made of polyethylene, polypropylene, sellotape, etc. is wound spirally around the outer circumferential surface of the prepreg 2.
Next, this is put into an outer mold 4 having an oval cross section and pressure molded to form the outer cross section into an oval shape.Then, the prepreg 2 is heated under pressure and heat cured.
The thermosetting synthetic resin impregnated with the resin is fluidized and hardened within the prepreg 2, and the prepreg 2 is hardened and molded into an elliptical cross-section as shown in FIG.
次にこれを外型４・４から取り出して芯金１を

浸したものである。 The tape 3 is wound to such an extent that the prepreg 2 is not wrinkled during pressure molding by the outer molds 4, 4, or openings are formed between the fibers of the woven fabric or aligned fiber sheet constituting the prepreg 2. Prepreg 2 is a woven fabric or aligned fiber sheet made of high-strength reinforcing fibers such as glass fiber or carbon fiber, similar to those used in conventional fishing rods, and thermosetting resin such as epoxy resin or polyester resin is coated in half. It is impregnated in a dry state.

れた特徴を有する。Effects of the Invention The present invention involves wrapping a tape around the outer circumferential surface of the prepreg when the prepreg wrapped around a core metal is placed in a non-circular outer mold such as an oval cross section and pressurized to forcibly transform the prepreg. Since the prepreg does not come into direct contact with the outer mold, wrinkles do not occur in the prepreg layer, causing unevenness on the surface of the fishing rod, and the fibers of the prepreg do not become open, reducing the strength of the fishing rod. At the same time, the tape prevents the occurrence of internal distortion due to expansion and contraction due to the difference in thermal expansion coefficient between the prepreg and the outer mold during heat curing, making it an excellent product that can easily and efficiently manufacture non-circular hollow fishing rods without bending. Has characteristics.
