この発明は、特に抜群の強靭性と弾性率を有するスキー
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to skis having outstanding toughness and modulus of elasticity.
従来、スキーの芯材に貼着する強化板の補強繊維として
、ガラスＨｈ維、炭素繊維等が使用されてきたが、これ

なったのである。特に近年優れた特性を有するセラミッ
クスか数多く開発されたが、これを補強する適当な補強
繊維が存在しなかったのである。Conventionally, glass Hh fibers, carbon fibers, etc. have been used as reinforcing fibers for reinforcing plates attached to the core material of skis, but these fibers have poor heat resistance and poor wettability with various matrices. Even though the fiber itself has excellent properties, when it is molded into a matrix to form a reinforcing plate, it is not always possible to obtain satisfactory toughness. In particular, many ceramics with excellent properties have been developed in recent years, but no suitable reinforcing fibers existed to reinforce them.

ックスを組合わせて補強板を製作し、これをスキ〒に応
用した結果、特にセラミックスを補強する繊維としては
、高度に耐アルカリ特性を有するシラス繊維が最適であ
ることを知り本発明を完成した。The present inventor created a reinforcing plate by combining many inorganic and organic synthetic fibers with various matrices, and as a result of applying this to skis, the inventor found that it has a highly alkali-resistant property, especially as a fiber for reinforcing ceramics. The present invention was completed based on the knowledge that the shirasu fiber having the above-mentioned properties is optimal.

とを目的とするものである。In other words, this invention is capable of exhibiting the outstanding toughness and high elastic modulus of shiras fibers by molding shirasu fibers into a thin plate shape using ceramics, metal, or plastics and attaching this to a core material. The aim is to provide skis with a high level of quality.

& Matricillas to be molded as miscellaneous include Cerami Shirasu, Plasti 1. Although either wood or metal can be used, this fiber has alkali resistance properties not found in other reinforcing fibers, so it can exhibit the most excellent characteristics when used together with ceramics. Note that epoxy resin is mainly used as the plastisilas, and aluminum alloy is mainly used as the metal.

表面化粧板、５は滑走面板である。Next, an embodiment of the ski according to the present invention will be described based on the drawings. ``■'' is a thin plate made of glass fibers molded into a thin plate shape, and this thin plate 1 is attached to the core material 2. . When this pasting is carried out, the core material 2 may be attached to one or both of the upper and lower sides. In the figure, 3 is a side plate, 4 is a decorative surface plate, and 5 is a sliding face plate.

ーが得られるという効果を有する。As mentioned above, in the ski according to the present invention, the shirasu fibers are attached to the core material together with the matrix in the form of a thin plate, so the outstanding toughness and high elasticity of the shirasu fibers are directly exhibited in the ski. This has the effect of providing extremely excellent skiing.
