Ski, or other gliding board having rigid and distinct sidewalls and method of making the same

A ski, etc has two longitudinal side faces formed by discrete rigid elements that include non-corrodible metallic particles. Independent claims are included for the following: (a) Forming an element for use as above by adding metallic particles to a polymer and extruding the mixture. (b) Forming an element for use as above by repeatedly building up on a sheet of thin paper first a layer of thermally curable resin and then a layer of metallic particles. The stacked layers are compressed and released after the resin has cured. The cured stack is cut into lengths. Preferred Features: The particles are flakes 5-100 micro,m in length or balls of about 100 micro,m diameter. Un ski, ou une autre planche de glisse sur neige, présente les deux bords latéraux et longitudinaux qui sont constitués par des éléments en longerons rigides distincts (6, 7) appelés « chants ». Ces chants (6, 7) comportent, incorporées et réparties dans leur structure, une multitude d'inclusions métalliques discrètes (11), en métal inaltérable à la corrosion et d'aspect brillant. Ces chants sont réalisés en matériaux polymères thermodurcissables ou thermoplastiques.
