Description of the Related Art As a screw forming method for integrally providing a screw on a laminated pipe such as a fishing rod, there is a method described in JP-A-62-51939. This consists of spirally winding a core material made of expandable synthetic resin around the outer circumference of the fishing rod body, winding a projection prepreg made of high-strength fiber around the outer circumference, and then mounting a die on the outer circumference. Then, the foaming synthetic resin is foamed by heating and the projecting prepreg is pressed against the mold to form a screw thread.

断強度を低下させるおそれがある。However, the screw thread produced by the above method has the structure shown in FIG.
That is, the foaming synthetic resin has a weak foaming force, and the core material 1 cannot properly push up the protrusion prepreg 3 to the inner surface of the mold where the screw thread 2 is to be molded. Further, the fibers 3a in the protrusion prepreg 3 are long fibers and do not flow into the concave portion on the inner surface of the mold, and only the resin 3b enters the concave portion. For this reason, the threaded portion 2 has a lacking portion 4, and even the resin 3b may not be sufficiently filled in the recess. For this reason, it is difficult to mold a screw that can withstand use as the thread 2. Furthermore, since the resin 3b is separated from the fibers 3a, the bubbles 5 are concentrated and generated below the screw threads 2, which may reduce the interlayer shear strength of the laminated tube.

According to this example, as shown in FIG. 1, the male screw 6 was molded nicely. When this cross section (parallel to the central axis of the laminated tube) was observed with a microscope and the thickness was measured, the surface of the male screw 6 was covered with the fabric of the ultrathin carbon fiber fabric prepreg 10 and the lower part thereof was covered with the nonwoven fabric prepreg 9. It was uniformly filled with the short fibers 9a, and no bubbles were generated. This is because the non-woven fabric prepreg 9 is softened by heating so that the fluidity is improved, and the fibers of the non-woven fabric are short fibers and are not restrained, so that the fibers easily move from the valley portion of the male screw to the mountain portion together with the resin. caused by. As shown in FIG. 3, the reel seat device 14 was attached to the thick portion and the nut 15 having a female screw of the same size was screwed onto the male screw 6, but the operating state and strength were good. .

The surface layer of the male screw or the female screw can be covered with continuous fibers without leaving bubbles in the object. Therefore, it is possible to obtain a laminated tube having a male screw or a female screw that has high strength and is less likely to peel. Further, the surface of the male screw or the female screw can be made smooth from the initial stage of molding, and post-processing such as grinding can be omitted.

層間剪断強度を低下させるおそれがある。However, the screw thread produced by the above method has the structure shown in FIG.
That is, the foaming force of the foaming synthetic resin is weak, the core 1 can not be attached properly press projection prepreg 3 to the mold inner surface to be molded a screw thread 2. Further, since the high-strength fiber 3a in the prepreg 3 for the protrusion is a long fiber, it does not flow into the recess on the inner surface of the mold, and only the resin 3b enters into the recess.
For this reason, the threaded portion 2 has a lacking portion 4, and even the resin 3b may not be sufficiently filled in the recess. For this reason,
It is difficult to mold a screw that can withstand use as the thread 2. Furthermore, since the resin 3b is separated from the fibers 3a, the bubbles 5 are concentrated and generated below the screw threads 2, which may reduce the interlayer shear strength of the laminated tube.

According to this example, as shown in FIG. 1, the male screw 6 was molded nicely. When this cross section (parallel to the central axis of the laminated tube) was observed with a microscope and the thickness was measured, the surface of the male screw 6 was covered with the fabric of the ultrathin carbon fiber fabric prepreg 10 and the lower part thereof was covered with the nonwoven fabric prepreg 9. It was uniformly filled with the short fibers 9a, and no bubbles were generated. This is because the non-woven fabric prepreg 9 is softened by heating so that the fluidity is improved, and the fibers of the non-woven fabric are short fibers and are not restrained, so that the fibers easily move from the valley portion of the male screw to the mountain portion together with the resin. caused by. As shown in FIG. 3, the reel seat device 14 was attached to the thick portion and the nut 15 having a female screw of the same size was screwed onto the male screw 6, but the operating state and strength were good. .
