ABSTRACT:
The core structure of a ski board has a heterogeneous internal construction formed of superposed layers of materials having significantly different Young's moduli to impede transmission of impulsive elastic waves therethrough, thereby mitigating direct transfer of impact load imposed on the ski to the skier's feet. Further use of prepreg layers for bonding the superposed layers results in highly internal energy-packed construction making the ski keenly responsive and predictable and thereby giving the skier a smooth, lively "feel", combined with great tolerance.
