Abstract

The ski described is characterized by the use of a selected fiber reinforced material comprising a sheetlike textile material and a thermoset resin, the fiber content being 30-70% by weight and the fiber being not less than 30% by weight synthetic. This material is notable for high flexibility and high restoring forces and confers excellent properties on the ski, for example good vibration damping.
