SKI WITH A SHEAR-STRIKE CORE COMPOSED OF FIBER-REINFORCED POLYURETHANE.

摘要

A ski is constructed of a top plate separated from a bottom plate by a core made of a material elastic in shear. Each of the top plate and bottom plate is formed of at least two layers, one above the other, with one layer having a higher coefficient of linear expansion than the other. The thicknesses and positional sequence of the layers are asymmetrically arranged with respect to the longitudinal center plane of the ski. The thicknesses of the layers varies considerably between the top and bottom plates.
