Abstract
The invention relates to an energy-absorbing laminate with improved torsion strength, particularly a ski, comprising a rigid core which is covered on at least part of its plane surfaces with a grid structure (2). The grid structure comprises a number of series of parallel elastomer strips (4, 5) which are reinforced with twisted filament bundles (3) running in the longitudinal direction of the strips. The series of strips intersect each other at an angle .alpha. between 10.degree. and 120.degree. and are bonded to one another in the common contact areas (6).
