Abstract

A fiber glass reinforced plastic (FRP) reinforced ski board, and particularly a FRP reinforced thin plate in which reinforcing fibers are arranged only in a desired area or in which the density of the desired area is higher than that of the other portions. The conventional FRP reinforced ski board cannot offer breakage resistance strength and crack prevention at the same time. This ski board limits the area of the weft reinforcing yam arrangement to the desired portion only, or arrange the fibers in such a manner that the weft density is the desired area in higher than that in the other areas. Thus, this ski board provides both breakage resistance strength and a crack preventing function, which cannot be obtained in the conventional FRP reinforced ski board.

The weft threads are arranged so that they are evenly distributed over the entire area of the board, but the weft threads are arranged only in the areas where necessary on the ski board or at high density in the desired areas.

Some have been attached to the ski core.
前者の F R P補強ス キ ー板すなわちス キ ー板の長手方 向のみに縦糸が配設されたス キ ー板は、 横糸が存在し いために縦糸が曲げ られる こ とが ¾ く 、 従ってス キ ー板 の耐折損強度、 耐疲労強度およ びアー チベ ン ト 保持能力 等の点は横糸を配設 したス キ ー板 よ ]) も むしろ優れた性 能を発揮する も のである。 しか し が ら、 横糸が存在 し ないため、 ビ ンディ ング取付け時に ビ ス の螺入に よって ひび割れを生 じ易い こ と、 ビ ン デ ィ ン グ取付け用 ビ ス と ス キ ー板と の保持力が低い こ と、 ス キ ー滑走時にス キ ー 板の縦割れや捩れが生 じ易い こ と、 お よ びス キ ー板の仕 一 i C ',:;I 上げ加工時に 力 ッ タ — に よってス キ ー板の端部にひび割 れが生 じ易い こ と 等の欠点があった。 The former FRP-reinforced ski plate, that is, a ski plate in which warp threads are arranged only in the longitudinal direction of the ski plate, is not warped because there are no weft threads, and therefore the ski In terms of breakage strength, fatigue strength, archival holding capacity, etc., the skid board provided with the weft thread] also exhibits excellent performance. However, since there are no weft threads, it is easy for the screw to be screwed in when installing the binding, causing cracks, and for holding the binding mounting screw and the ski plate. The low force and the tendency of vertical cracking and twisting of the ski plate during skiing make it easy to match the ski plate and the ski plate. I C ',:; I There was a defect that cracks tended to occur at the edges of the ski plate due to the force applied during the lifting process.

Therefore, although the above-mentioned drawbacks such as cracking of the FRP reinforced ski plate composed only of the warp yarns can be solved, the warp yarns are bent at the intersection with the warp yarns due to the presence of the weft yarns. There is a drawback in that the reinforcing ability of the warp yarn against the external force in the longitudinal direction of the ski plate is reduced, and thus the breakage resistance of the ski plate is reduced. In the FRP reinforced ski board using the cross-reinforced body, the warp and weft intersections are present over the entire area of the ski board, so that the ability to reinforce the warp threads in the longitudinal direction is particularly remarkable. It will be slowed down. In addition, in order to manufacture a ski plate with FRP reinforced skis using cross reinforcements and having a breakage strength equivalent to that of FRP reinforced skis consisting only of warp threads, FRP reinforced skis should be used. There is a drawback in that the thickness of the thin plate has to be made thicker, the weight of the ski plate also increases correspondingly, and the manufacturing cost becomes higher.
