スチツクスで成型したFRPを製造し、これを利
用してスキーに強靭性を与える技術の開発が望ま
れていたのである。 Conventionally, in order to give skis toughness, various reinforcing materials (carbon fiber, silicon carbide, glass fiber, alumina silica, etc.) were kneaded into plastics and molded into a thin plate (FRP), which was attached to the core material. However, although these reinforcing materials had considerable toughness on their own, they were not as strong as FRP due to poor wettability and adhesion with plastics. It is. This has been explained by the fact that since most of the conventional reinforcing materials that were effective were inorganic materials, they had poor integration with plastics, which are organic materials. Therefore, there was a desire to develop a technology to manufacture FRP molded from plastics and an organic material that has good integration with plastics and is strong in itself, and to use this to provide toughness to skis. .
そこでこの考案は、太さ１〜3μ、最長150μ前
後の針状の単結晶が数十〜数百本、あたかもウニ

材であるポリオキシメチレンホイスカーとプラス
チツクスにより成型されたFRPの保有する抜群
の強靭性をスキーにおいて発揮させるようにする
ことを目的として開発したものである。 Therefore, this idea was created by molding polyoxymethylene whiskers, which have a shape similar to a sea urchin, into a thin plate of plastic, consisting of dozens to hundreds of needle-shaped single crystals with a thickness of 1 to 3 μm and a maximum length of around 150 μm. By attaching this to a core material, we will be able to make use of the outstanding toughness of FRP, which is made of plastic and polyoxymethylene whiskers, which are reinforcing organic materials, in skis. It was developed for this purpose.
次にこの考案係るスキーの一実施例を図面に基

は側板、４は表面化粧板、５は滑走面板である。 Next, an embodiment of the ski according to this invention will be described based on the drawings. Reference numeral 1 is a thin plate made of polyoxymethylene whiskers molded with epoxy resin, and this thin plate 1 is attached to a core material 2. When attaching the thin plate 1 to the core material 2 in this manner, the core material 2 may be attached to one or both upper and lower surfaces. In addition, 3 in the drawing
4 is a side plate, 4 is a decorative surface plate, and 5 is a sliding face plate.
次にポリオキシメチレンホイスカーの製造方法
の一例を述べると次のとおりである。 Next, an example of a method for producing polyoxymethylene whiskers will be described as follows.
トリオキサン（化学式（CH2O）3）のシクロヘ
キサン溶液を乾燥剤で乾燥し、カチオン触媒であ
る三フツ化ホウ素（BF3）と極く微量の水を加え
て振溢後静置するとポリオキシメチレンホイスカ
ーの針状結晶が生成することができる。 Dry a cyclohexane solution of trioxane (chemical formula (CH 2 O) 3 ) with a desiccant, add boron trifluoride (BF 3 ), a cationic catalyst, and a very small amount of water, shake it, and let it stand to form polyoxymethylene. Whisker needle-like crystals can be produced.
ここで生成するポリオキシメチレンホイスカー
は太さ１〜3μ、最長150μ前後の針状の単結晶が
数十〜数百本、あたかもウニのような形状をして
いるものである。 The polyoxymethylene whiskers produced here are dozens to hundreds of needle-shaped single crystals with a thickness of 1 to 3 microns and a maximum length of around 150 microns, resembling a sea urchin.
このポリオキシメチレンホイスカーはプラスチ
ツクスとの〓ぬれ性〓及び〓密着性〓が従来の補
強材に比較して抜群に優れており、また、ヤング
率が１×1011N／m2と、力学的特性にもすぐれて
いる。さらにポリオキシメチレンホイスカーは比
重が1.49を炭素繊維（比重1.7）よりも軽いので、
スキーの軽量化にも資するものである。 This polyoxymethylene whisker has outstanding wettability and adhesion with plastics compared to conventional reinforcing materials, and has a Young's modulus of 1×10 11 N/m 2 , making it mechanically It also has excellent physical characteristics. Furthermore, polyoxymethylene whiskers have a specific gravity of 1.49, which is lighter than carbon fiber (specific gravity 1.7).
This also contributes to reducing the weight of skis.
前記のようにこの考案に係るスキーによれば、
太さ１〜3μ、最長150μ前後の針状の単結晶が数
十〜数百本、あたかもウニのような形状を有する
ポリオキシメチレンホイスカーをプラスチツクス

てあるので、従来に無い強靭なスキーが得られ、
その効果はきわめて大である。 As mentioned above, according to the ski according to this invention,
Polyoxymethylene whiskers, which are shaped like sea urchins and have dozens to hundreds of needle-shaped single crystals with a thickness of 1 to 3 μm and a maximum length of around 150 μm, are molded into a thin plastic plate and used as the core material. Since it is constructed by pasting it, you can get a stronger ski than ever before.
The effect is extremely large.
