| Development |
Over the years, manufacturers have tried many ways of solving the technical challenges posed by ski construction. A number of different systems are used, many of which involve laminating or layering various materials.
Alternatively, some manufacturers build their skis around a polyurethane foam core, or a carefully designed metal 'torsion box'.
Most advanced is the monocoque design, in which the upper surface of the ski is not merely cosmetic but, by curving down to meet the edges, actually provides the ski's strength and stiffness.

| Material technology |
Ski designers have always been quick to exploit new advances in material technology, both for performance and marketing reasons.
Although wood is still used, it is usually as a 'filler' to keep the weight of the ski down. Aluminium or fibreglass are most commonly used to provide strength, although increasing numbers of skis include Kevlar, titanium, carbon or even boron fibres.
As a general rule, the more exotic-sounding the material, the less of it is actually present and the more expensive your ski is.
