ことを発見して本発明を完成した。Ski core materials have been required to have excellent properties such as bending strength, elasticity, vibration absorption properties, impact resistance, and fracture resistance.In the past, ski core materials with particularly excellent vibration absorption properties were It didn't exist. As a result of repeated research, the inventor found that a material made by dispersing fine ferrite particles into a polyester resin has a specific gravity (approximately 6) that is dispersed in the resin. It was discovered that because large ferrite particles and elastic resin interfere with each other, it has outstanding vibration absorption properties compared to wooden ladles, light metals, plastics, etc. that are generally used as core materials for skis. The present invention was completed.

的をもって開発したものである。In other words, the present invention involves molding a ski core material with a ferrite-polyester resin composite material containing 0.3 parts by weight or more of a polyester resin per 10 parts by weight of fine particles of ferrite. It was developed with the aim of providing a core material for skis that can take full advantage of the outstanding vibration absorption properties of composite materials.
