<p>A runner (20) for gliding over snow is disclosed that includes a thermoplastic composite structural layer (28). The runner is preferably a snow ski. The snow ski includes an outer layer (24), a core (22), a structural layer (28), a base (26), and edges (30). The core has upper and lower surfaces and two lateral sides. The structural layer is joined to the outer layer and is made of a thermoplastic material having multidirectional, high-modulus reinforcing fibers embedded within the thermoplastic. The thermoplastic material (28) is disposed across the upper surface and along the lateral sides of the core (22) and joins the outer layer to the core. The base (26) has a bottom sliding surface for contact with the snow, lateral sides, a top surface. The top surface of the base is joined to the core and includes a resin-impregnated fiber material (32) for structural rigidity. The edges extend longitudinally along the lateral sides of the base. The disclosure also includes a method of manufacturing the ski by joining a thermoplastic composite layer to an outer layer, molding the joined layers into a top cap, placing the top cap and a base within a jig, and injecting foam between the base and top cap.</p> |
