A fiber-reinforced depolymerizable and repolymerizable thermoplastic composite that is encased in a depolymerizable and repolymerizable thermoplastic resin exhibits the strength and stiffness that make the encased composite particularly suitable for a wide array of applications that require very high strength, stiffness, and exceptional impact, together with complex shape. Examples of such applications include bumper beams, pedals, car door structures, instrument panels, and seating structures for automotive use. Other applications include window profiles, skis, ski poles, mast stays, tent poles, concrete reinforcement, crash barriers, window or door lineals, cable trays, cable for optical fibers, bicycle wheels and frames, and pipe.
An encased article comprising a) a depolymerizable, repolymerizable thermoplastic polymer composite that is reinforced with fibers that extend through the length of the composite and are at least 100 mm long;
A process for preparing a fiber-reinforced rigid thermoplastic polyurethane composite article encased in a thermoplastic comprising the steps of drawing a fiber bundle continuously through a melt obtained by heating a rigid thermoplastic polyurethane that contains a hydrolytically- and thermally-stable catalyst to a temperature sufficient to depolymerize the thermoplastic polyurethane;
