ることができる。(Prior art) Conventionally, the reinforcing plates bonded to the upper and lower surfaces of the core material of skis are fiber-reinforced plastic plates (hereinafter referred to as
It is constructed using FRP board). FRP board is a single fiber woven fabric such as glass fiber or carbon fiber.
Alternatively, the fibers are formed by aligning a large number of fibers, or by weaving them with other fibers and arranging them alternately, and by impregnating and hardening a synthetic resin mainly by prepreg molding.
Since the thickness of these fibers is 5 to 20 microns for glass fibers and 6 to 8 microns for carbon fibers, they can be formed into a smooth plate even in the case of alternately arranged cloth.

はある。 On the other hand, boron fiber is known as one of the inorganic fibers, and is attracting attention as a lightweight structural material due to its high specific strength, specific stiffness, and specific elasticity. In particular, the elastic strength of an epoxy resin matrix FRP board is about 1.5 to 5 times that of carbon fiber or glass fiber.

つた。(Problem to be solved by the invention) However, since boron fibers require a tungsten wire as a core wire to generate, the price increases exponentially when the diameter is made thinner, so boron fibers with a size of about 100 μφ are required. It is appropriate to use When boron fibers of about 100μφ are used in an alternately arranged cross shape to create an FRP board, the boron fibers are exposed on the board surface even after being impregnated with synthetic resin and hardened, and the boron fibers are removed during the subsequent processing process. There was an issue where the fibers were easily damaged. In particular, boron fiber, like other inorganic fibers, is a brittle material, so even if it is within its elasticity, it may suddenly break due to small scratches on its outer surface, making it dangerous to use as a reinforcing plate for skis. There was an issue of high gender.

However, in these conventional examples, since the solid plates are bonded to each other, an interface is created, and when bonding with an adhesive, air bubbles are likely to be generated, and the air bubbles may cause deterioration in strength. In ``Skis'' in 1987-617, there is a description that FRP prepreg reinforcing material is wrapped around the core. However, this example also had the problem of poor compatibility with each other because the core, which is considered to be a solid plate, and the prepreg FRP were bonded together.

The reinforcing board 2 consists of a boron fiber reinforced plastic board 7 (hereinafter referred to as BFRP board) and an upper and lower fiber reinforced plastic board 8 (hereinafter referred to as FRP board).
Formed by coating. The BFRP7 board is formed by impregnating and curing a synthetic resin such as epoxy into a single boron fiber, a cross shape, or a stretched boron fiber by a pulling method. The thickness of boron fiber is 4.0mils, 5.6mils, 8.0mils (/
mils=25.40005μ), but in this embodiment, one with 4.0mils (approximately 101.6μ) is used. The band-shaped plate is formed by prepreg molding, but hand lay-up molding or other molding methods may be used. The width of the BFRP strip varies depending on the overall size of the reinforcing plate, and is usually formed to 5 to 30 mm.
A wide board may be cut into widths of the above-mentioned size, and in this embodiment, three boards each having a width of 7 mm are arranged in parallel. As another embodiment, one wider one or a number of narrower width ones may be arranged side by side. The FRP board 8 is formed by making glass fibers, carbon fibers, or other synthetic fibers into a woven fabric or synthetic fabric, and impregnating and curing a synthetic resin such as an epoxy resin by hand lay-up molding. In this embodiment, the FRP board 8 is a glass fiber reinforced plastic board. The impregnated synthetic resin of the FRP board 8 is in an uncured state before the BFRP board 7 is bonded between the two sheets. This is a state in the middle of a molding process such as hand lay-up. The FRP board 8 in which this impregnated synthetic resin is in a partially cured state is used as a lower layer, and an appropriate number of BFRP boards 7 are arranged on top of it to serve as an intermediate material, and further on top of that is an FRP board 8 similar to the lower layer.
Place. At this time, the BFRP board 7 is reliably aligned and bonded due to the leakage of the uncured synthetic resin from the FRP board 8. Due to the heating of the next process, hot press forming.
After the surface synthetic resin of BFRP board 7 has been softened, it becomes FRP.
It recures as the synthetic resin of plate 8 hardens, so
BFRP board 7 and FRP board 8 are completely integrated reinforcing board 2
becomes.

The carbon fiber reinforced board has approximately 59% of the elasticity, and the boron fiber reinforced board can achieve similar elasticity with a configuration that is approximately 1/4 the width of the glass fiber reinforced board.

破壊性を有するという効果がある。(Effect of the invention) Therefore, in this invention, boron fiber-reinforced plastic and fiber-reinforced plastic are both in the prepreg state, so they are easily compatible with each other, and without creating an interface, boron fiber-reinforced plastic is covered with fiber-reinforced plastic and heated. Even if it is pressurized and embedded in fiber-reinforced plastic and integrated into a plate-like body, no strength deterioration occurs. Furthermore, since this invention has the above-mentioned configuration, when bonding the reinforcing plate to the core material, the surface of the reinforcing plate is generally subjected to a sanding process to enhance the wetting of the adhesive and the anchoring effect. Since the boron fibers are not exposed on the surface of the reinforcing plate, bonding can be performed without damaging the boron fibers. In addition, since boron fiber has a very high elasticity compared to other fibers, its width can be made narrower, and the reinforcing plate, which conventionally required a three-layer structure, can now be made into two layers (top and bottom), and can be used as an intermediate material. Thinner BFRP
By providing the plate, it is possible to construct a structure that is relatively lightweight and has high elasticity. Furthermore, when this invention is used in skis, especially when used on the upper surface of the core material,
It has the effect of having very strong breakage resistance against the vertical bending movement of the ski.
