Abstract

A method of making a novel ski having viscoelastic properties is disclosed. The ski is composed of continuous reinforcing fibers embedded in a matrix of an elastomer modified syntactic plastic foam. The fibers are arranged so as to be at an angle of 0° and 90° with respect to the longitudinal axis of the ski.
