〔産業上の利用分野〕
本発明は発泡樹脂板を中芯材とするプラスチックスキー
の製造法に係るものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing a plastic ski using a foamed resin board as a core material.
従来、発泡樹脂板を中芯材とするプラスチックスキーは
特公昭６２−７１２号公報に示すように、スキー成形金
型内に下部材と上部材を中間に空間が出来るように配在
せしめ、この中間部に発泡樹脂を混入し、発泡硬化せし
めている。Conventionally, plastic skis with a foamed resin plate as the core material are produced by placing the lower member and the upper member in a ski molding mold so that there is a space in between, as shown in Japanese Patent Publication No. 62-712. Foamed resin is mixed in the middle part and foamed and hardened.
このようなエンジェクションスキーは発泡樹脂製品の中
芯材を補強する為に上下にＦＲＰシートを多層に積層し
て曲げ強度やねじれ強度を確保している。In order to reinforce the core material of the foamed resin product, such injection skis have multiple layers of FRP sheets laminated on the top and bottom to ensure bending strength and torsional strength.
また成型に際しては注入空間を保持せしめる為金型内に
上部材を支承保持する支持部材などを架設したり、上部
材を吊下する吊下材を設けたりするなどの配慮が必要と
なり、それだけ成型を厄介にする欠点があった。In addition, when molding, in order to maintain the injection space, consideration needs to be taken such as installing a support member to support and hold the upper member in the mold, and providing a hanging material to hang the upper member. There was a drawback that made it troublesome.
本発明はこの欠点を解決するも゛のでプラスチックスキ
ーの製造法を提供するものである。The present invention seeks to overcome this drawback and therefore provides a method for manufacturing plastic skis.

経芯材１を長さ方向に間隔ｅを置いて並列に且つ上下に

とを特徴とするものである。Reinforced fiber warp core materials 1 such as glass fibers, carbon fibers, and metal fibers are arranged in parallel at intervals e in the length direction and in multiple stages at intervals above and below. Similarly, reinforcing fiber weft core materials 2 are arranged alternately in the left-right direction at intervals i in the material 1, and reinforcing warp core materials 3 are arranged in parallel in a vertical meandering manner between the upper and lower stages, and are made of thermosetting resin or thermoplastic resin. The three-dimensional woven core frame a, which has been reinforced and bonded, is used as a reinforcing core material for a ski core plate made of foamed resin, and the lower member 5 and the three-dimensional woven core frame a1 and upper member 6 are placed in the ski molding mold 4. It is characterized by laminating the fabric, injecting foamed resin into the three-dimensional fabric core frame a, and foaming and curing it.
又、下部材５に滑走板７と補強板８を併用しても良い。Furthermore, the sliding plate 7 and the reinforcing plate 8 may be used together with the lower member 5.
又、上部材６に表面板９と補強板８を併用しても良い。Further, the top member 6 may include a surface plate 9 and a reinforcing plate 8 in combination.
〔効 果〕
本発明においては中芯材となる発泡樹脂板が特殊な強化
プラスチック製の三次元織物芯枠で補強されているから
非常に秀れた曲げ強度やねじれ強度を有するスキーとな
り、その分だけ高価なＦＲＰシートのような補強材を節
約し得ることになる。[Effects] In the present invention, the foamed resin plate serving as the core material is reinforced with a three-dimensional woven core frame made of special reinforced plastic, resulting in a ski with extremely excellent bending and torsional strength. Therefore, it is possible to save on reinforcing materials such as expensive FRP sheets.
例えば、夫々上下に５枚づつ、配したものを半分位に節
約しても三次元織物芯枠の存在の為曲げ強度やねじれ強
度は低下しない。For example, even if five layers are placed on each side, the bending strength and torsional strength will not decrease because of the presence of the three-dimensional fabric core frame.
特に発泡樹脂板の厚さ方向に対しても補強経芯材が蛇行
状態に配されているから一層秀れたねじれ強度を発揮す
ることになり、それだけ補強材の節約量を増加し得るこ
とになり、補強材を無くしても使用し得るスキーとなる
。In particular, since the reinforcing core material is arranged in a meandering manner in the thickness direction of the foamed resin board, it exhibits even better torsional strength, and the amount of reinforcing material saved can be increased accordingly. This results in a ski that can be used even without the reinforcing material.
その上三次元織物芯枠はそれ自体厚みを有する枠構々成
を有し、且つ強化プラスチック加工により充分な強度を
有するものであるからそのまま上部材を支承保持するこ
とになり、三次元織物芯枠だけで発泡樹脂の注入空間を
確保することになり、注入空間保持の為特別な構造を必
要としない。Moreover, the three-dimensional fabric core frame itself has a thick frame structure, and has sufficient strength due to reinforced plastic processing, so it supports and holds the upper member as it is, and the three-dimensional fabric core The frame alone secures the injection space for the foamed resin, and no special structure is required to maintain the injection space.
従って発泡樹脂の注入はこの三次元織物芯枠の中に注入
すれば良いことになり、極めて作業性、生産性の秀れた
プラスチックスキーの製造法となる。Therefore, the foamed resin can be injected into this three-dimensional woven core frame, resulting in a method of manufacturing plastic skis with excellent workability and productivity.
