【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、波状及びＸ並列状織物を用いた繊維強化プ
ラスチックス複合体からなるスキー板用芯材に関するも
のである。Description: TECHNICAL FIELD The present invention relates to a ski core made of a fiber-reinforced plastics composite using wavy and X-parallel woven fabrics.
一般にスキーのねじり剛性を高くする方法としては、 芯材を所謂サンドイッチ構造,BOX構造にするという構
造上の配慮。Generally, a method of increasing the torsional rigidity of skis is to consider the structure by using a so-called sandwich structure or BOX structure for the core material.
芯材をガラス繊維，炭素繊維，ジュラルミン等の素材
で構成するという使用素材上の配慮。Consideration on the material used, as the core material is composed of glass fiber, carbon fiber, duralumin, etc.
芯材を繊維材で構成する場合においてその繊維の配向
方向をバイアス状等にするという繊維配向上の配慮。When the core material is made of fiber material, consider the fiber orientation such that the fiber orientation direction is biased.
等が考えられる。Etc. are possible.
これを例えば図式的に示せば、 これらの公知事実をもとに適正なねじり剛性を得るべ
く種々の実験が繰り返され、種々のスキー板用芯材21が
提案されている。If this is shown schematically, for example, Based on these known facts, various experiments have been repeated in order to obtain appropriate torsional rigidity, and various ski core materials 21 have been proposed.
（ａ）例えば、木材や発泡ウレタンで構成されているス
キー板用芯材の場合は、スキー板の長さ方向に高い剛性
を付与するものの、幅方向には高い剛性を付与し得な
い。(A) For example, in the case of a ski ski core made of wood or urethane foam, high rigidity is imparted in the longitudinal direction of the ski, but high rigidity cannot be imparted in the width direction.
従って、これらの芯材により構成されたスキー板は、
所望通りの曲げ剛性を得られても、所望通りのねじり剛
性は得られないという欠点がある。Therefore, the ski made of these core materials,
Even if the desired bending rigidity is obtained, the desired torsional rigidity cannot be obtained.
即ち、ある程度の硬さを持ったスキー板は得られる
が、その半面ねじれ易いスキー板となるということであ
る。That is, although a ski having a certain degree of hardness can be obtained, the ski can be twisted halfway.
（ｂ）また、（ａ）に示した欠点を補うため、芯材の上
下にジュラルミンあるいは繊維強化プラスチックスのシ
ートを配するという方法で所望通りのねじり剛性を得た
スキー板は、スキー板の質量が重くなり、スキー滑走時
の滑走性，回転性を損なうばかりか、構成材料増による
コスト高をまねいてしまうという欠点を生ずる。(B) Further, in order to make up for the drawbacks shown in (a), a ski having a desired torsional rigidity obtained by arranging sheets of duralumin or fiber-reinforced plastics above and below a core is The mass becomes heavy, which impairs the gliding property and the rotatability during skiing, and also causes the disadvantage of increasing the cost due to the increase of the constituent materials.
（ｃ）また、別なスキー板として第28,29図に図示した
ように、アルミハニカム材22やペーパーハニカム材に発
泡ウレタン23を充填したものをスキー板用芯材21とする
ものや、第26,27図に図示したように発泡ウレタン23に
ガラス繊維24を厚さ方向に配設したものをスキー板用芯
材21とするものは、成形時の厚さに対してつぶれ防止の
効果はあるものの、ねじり剛性が十分に得られないため
先の（ｂ）に示したような方法でねじり剛性の不足分を
補っているという問題点がある。(C) As another ski, as shown in FIGS. 28 and 29, a ski core 21 made of aluminum honeycomb material 22 or paper honeycomb material filled with urethane foam 23, or As shown in FIGS. 26 and 27, the one in which the glass fiber 24 is arranged in the thickness direction in the urethane foam 23 as the ski core material 21 has the effect of preventing the crushing against the thickness at the time of molding. However, since the torsional rigidity cannot be sufficiently obtained, there is a problem that the shortage of the torsional rigidity is compensated by the method shown in (b) above.
ねじり剛性が十分に得られないというのは、木材，発
泡ウレタンに、ねじり剛性に寄与する繊維強化層（例え
ば斜め方向，横方向，あるいは厚さ方向に配された繊維
強化層）がないことによるものである。The reason why sufficient torsional rigidity cannot be obtained is that wood and urethane foam do not have fiber-reinforced layers that contribute to torsional rigidity (for example, fiber-reinforced layers arranged diagonally, laterally, or in the thickness direction). It is a thing.
ねじり剛性を高くするには例えばジュラルミン等を使
う為一般的にはスキー板の重量が重くなる訳であるが、
本発明は、スキー板芯材の重量を抑えつつ最適なねじり
剛性を得ることにできるスキー板用芯材を提供するもの
である。In order to increase the torsional rigidity, for example, duralumin is used, so the weight of the ski is generally heavy.
The present invention provides a ski core material capable of obtaining optimum torsional rigidity while suppressing the weight of the ski core material.
添付図面を参照して本発明の要旨を説明する。 The gist of the present invention will be described with reference to the accompanying drawings.

性が向上する。The ski core material according to the present invention can realize the optimum torsional rigidity as compared with the conventional core material made of wood or foamed urethane, because the woven cloth 1 and the plate-shaped woven cloth having a wavy or X-parallel cross-sectional shape. Since the fiber reinforced plastics 4 having the three-dimensional woven fabric 3 composed of 2 as the core material are used, the light weight plastics 6 are disposed in the void portion 5 of the core material, or the fiber reinforced plastics are provided above and below the core material. When the seat 7 is provided, the torsional rigidity is further improved.
発明者らは次の点に着目し、本発明に至った。 The inventors have paid attention to the following points and have arrived at the present invention.
イ）ねじり剛性は、次の（１）式によって表される。A) The torsional rigidity is expressed by the following equation (1).
GIp＝α×Ｇ×Ip ・・・（１） ここで Ip＝β×ｗ×hr GIp:ねじり剛性［kg/mm2］ α，β，γ：定数 G:材料のねじり弾性率［kg/mm2］ （材料の力学的パラメーター） Ip:その材料の断面２次極モーメント［mm4］ （材料の形状パラメーター） w:その材料の幅［mm］ h:その材料の高さ［mm］ この（１）式から、ねじり剛性を上げる為には次の点
が重要であるということがわかる。GIp = α × G × Ip ··· (1) where Ip = β × w × h r GIp: Torsional rigidity [kg / mm 2] α, β, γ: constant G: torsion modulus of the material [kg / mm 2 ] (Mechanical parameters of material) Ip: Second polar moment of area of the material [mm 4 ] (Geometry parameter of the material) w: Width of the material [mm] h: Height of the material [mm] From the equation (1), it can be seen that the following points are important for increasing the torsional rigidity.
高剛性の材料を使用する。Use high rigidity material.
材料の幅を広くする。Increase the width of the material.
材料の厚みを厚くする。Increase the material thickness.
軽い材料を使用する。Use light materials.
詳述すれば、 ロ）芯材に繊維強化層を設けることでねじり剛性を高め

の密度により左右される。尚、ここで、比ねじり剛性と
いうねじりに関する軽量化パラメーターを定義する。E) Considering the gliding and rolling characteristics when skiing, the relationship between torsional rigidity and weight is also an important factor. In a somewhat limited volume of ski core, the weight depends on the density of the material. In addition, here, a weight reduction parameter related to torsion, which is called specific torsion rigidity, is defined.
Gwr＝GIp/ρ ここで Gwr:比ねじり剛性 ρ：その材料の密度 以上、イ），ロ），ハ）の知見を総合すると、 「厚さ方向に適性に強化繊維を配すれば、強化繊維の特

これにニ）の知見を加えると、 「スキー板用芯材においては上下に繊維強化層を有し、
この間隔が大きければ大きいほどねじり剛性はいっそう
向上する。」 ということである。Adding the knowledge of 2) to this, "In the core material for skis, the upper and lower fiber-reinforced layers are
The larger this distance is, the more the torsional rigidity is improved. "That's what it means.
一方、ホ）の知見から、 「同じねじり剛性のスキー板用芯材なら密度の小さい方
が、滑走性，回転性の良いスキー板を得ることができ
る。」 ということである。On the other hand, from the findings of (e), it is possible to obtain a ski that has better running and rotation characteristics if the density is lower if the core has the same torsional rigidity.
