Abstract
This method relates to the manufacture of a gliding board having a non-rectangular cross-section including an upper assembly including at least one upper protective layer and a fibre stiffener impregnated with a thermosetting resin, a polyurethane foam-based core, and a lower assembly including a base of the board. The method involves placing the lower assembly and the upper assembly in a mould, and then injecting a reactive mixture into a space enclosed between the lower assembly and the upper assembly in order to produce an expanded polyurethane foam. The thermosetting resin used to impregnate the fibre stiffener is based on polyurethane and the expanded foam of the core comes into direct contact with the fibre stiffener.
