た。 Plastic products that use reinforcing materials, such as plastic skis, usually have sliding surface material, edges, and reinforcing material deformed into the desired shape in a mold, and then these are placed between the surface material and mold crimp plate. It is sealed and molded by foaming polyurethane resin in a sealed mold. The reinforcing material used for this purpose is to increase the strength of the plastic ski as a finished product. Conventionally, the reinforcing material is a woven material made of glass fiber, carbon fiber, etc., which is impregnated and hardened with resin such as epoxy or polyester. However, since conventional woven materials for reinforcing materials have both warp and weft made of glass fiber or carbon fiber, we use reinforcing material impregnated with resin and hardened to obtain the desired shape. When deforming into a shape, these glass fibers and carbon fibers are cut at the bending point, making it difficult to deform into a desired shape. Therefore, in the conventional method, the reinforcing material is not deformed after being impregnated with resin and cured, but the reinforcing material is formed in a special mold for deforming the reinforcing material. A method of impregnating and curing the reinforcing material with resin while deforming it was used to obtain a reinforcing material that was deformed into the desired shape.

強強度が得られないという欠点があつた。 First, such conventional methods have the disadvantage that a special mold must be manufactured for deforming the woven reinforcing material, resulting in extremely high ski manufacturing costs. Also, the second
Another drawback is that it is difficult to accurately arrange the reinforcing woven fabric member due to the special shape of the ski itself. In other words, when looking at the ski itself in the longitudinal direction, the width at the center is smaller than the width at the front and rear, creating a constricted shape, and the thickness at the center is smaller than the width at the front and back. Due to its unique shape, which is thicker at the front and thinner at the rear, the woven reinforcing material is likely to be crushed particularly strongly at the front and rear parts in the mold for molding skis. However, in the case of conventional woven reinforcing material, during this crushing deformation, the woven reinforcing material did not deform smoothly due to the special shape of the mold for ski molding. There was a drawback that the reinforcing woven fabric member was unevenly distributed, making it impossible to obtain the expected reinforcing strength.

にある。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a reinforcing material that can be easily deformed without cutting the fibers even after a woven material for reinforcing material is impregnated with a resin and cured.

0 is a warp thread 12 extending in the longitudinal direction of the ski, and a weft thread 14 arranged to intersect with this warp thread 12.
It consists of The warp threads 12 are made of various known high tensile strength fibers such as glass fibers or carbon fibers. In addition, the weft thread 14 is made of vinylon, nylon,
It may be composed of only organic fibers such as Tetron or Kevlar, or it may be composed of these organic fibers and high tensile strength fibers such as glass fibers or carbon fibers bound together. The former, in which the weft 14 is composed only of organic fibers, is inexpensive, but has a somewhat inferior ability to increase the torsional rigidity of the ski; This makes it possible to obtain skis with high torsional rigidity.

する等のごとく併用してもよい。 Since the embodiment shown in FIG. 1 shows a reinforcing material for skis, the types of fibers constituting the warp threads 12 and the weft threads 14 are as described above, but other plastic products other than skis can also be manufactured. For use as case reinforcement, the types of fibers making up the warp and weft may be reversed. In addition, the weft thread 14 is
Instead of using organic fibers and high tensile strength fibers in a bundle as described above, they may be used in combination by alternately arranging them at an appropriate pitch.

P1 and the pitch P2 of the weft thread 14 are also determined appropriately depending on the application. For use as a reinforcing material for foamed resins such as foamed polyurethane, especially in the production of plastic skis, the pitch P 1 of the warp threads 12 must be The pitch P2 of the weft thread 14 is set relatively large, and a gap 1 is created in the area surrounded by both threads.
6 is preferably formed so that the foamed resin can pass through this gap 16.

ことがない。 As described above, in the reinforcing material 10 of the present invention, the thread that undergoes bending (the weft thread 14 in the embodiment shown in FIG. 1 used for manufacturing skis) is an organic fiber or a combination of an organic fiber and a high tensile strength fiber. Because of this structure, even after the resin is impregnated and hardened, the thread that is subject to bending will not be cut during the bending process.
次に、本発明の補強材１０をプラスチツクスキ

2 shows a cross-sectional view of the reinforcing material 10 of the present invention, which is deformed so that the cross section is U-shaped, box-shaped, chevron-shaped, circular, etc., and is integrally molded inside the foamed polyurethane resin 22. It is something. Figures 1 to 6 in Figure 2 show longitudinal cross-sectional views at approximately the center of the ski in the longitudinal direction. Since these parts are thinner than the central part, the reinforcing member 10 is in a more compressed state than the state shown in FIG.

Even when deforming 0, since the weft yarn 14 is an organic fiber, it can be deformed without being cut.
Moreover, even if the front and rear parts of the ski are subject to significant crushing deformation, the reinforcing material can be smoothly deformed along with the mold.
