Abstract
A ski of laminated material which comprises at least one core layer of rigid material wherein at least a portion of at least one of its plane sides is covered with a rubberlike material having a loss tangent of about 0.1 and in which material twisted filament bundles are embedded, the filaments having a tensile strength of at least 2000 N/mm.sup.2 and a modulus of elasticity of at least 7.times.10.sup.4 N/mm.sup.2.
Claims10
A longitudinally extending ski of the laminated type comprising an elongated core of rigid material, a top external surface, a bottom skiing surface, and a layer of rubberlike material disposed in interbonding relationship between said core and at least one of said surfaces, said rubberlike material having a loss tangent of about 0.1 and having longitudinally extending twisted filament bundles embedded therein, the filaments having a tensile strength of at least 2000 N/mm.sup.2 and a modulus of elasticity of at least 7.times.10.sup.4 N/mm.sup.2.
