るものである。That is, this invention molds polyacetal mia into a thin plastic plate and attaches it to a core material, thereby achieving tensile strength and elongation comparable to those of metal, which polyacetal fibers have. The material is extremely lightweight (approximately 1/6 that of steel), which is utilized in skis.

次のようにすぐれた特性を有している。The polyacetal fiber used in this invention is a fiber produced by super-stretching polyacetal resin. In addition, polyacetal resin (polyacetal res
in) is a polymer having 7 cetal groups in the main chain and is a type of polyether, and is usually a formaldehyde polymer or copolymer. The homopolymer is called polyoxymethylene. It is a crystalline polymer with little branching and is used as an engineering plastic. Delrin (Delrin, du Pant) is a homopolymer.
), the co-polymer includes duracon, self-y (Dur
acon, Ce1con, Cellanese)
etc. In order to ultra-stretch this polyacetal resin and make it into fibers, the polyacetal resin is ultra-stretched in a highly crystalline state to 20 times or more the normal amount. Polyacetal wAm has the following excellent properties.
