Abstract
A method of making a sailboard or surfboard, in which a prefabricated foam core has fibrous material wound about it and a polyurethane resin especially set with a reaction retarder is poured onto the fibrous material, whereupon the thus treated foam core is inserted in a molding tool and the mold is closed for curing the polyurethane resin. Desirably, the mold is lined with a surface layer, particularly a deep drawn thermoplastic film, before the treated foam core is inserted. In this way one can make low-weight boards of high strength with relatively low production and material costs.
