This annual report describes an investigation of the use of long-fiber thermoplastic composites in transit bus applications for the Department of Transportation and the Federal Transit Administration. The goals of improved safety, reduced weight, and lower cost are very important to the transportation industry. Investigations into several candidate transit bus components were made to replace heavier conventional components with long-fiber thermoplastic components while simultaneously maintaining safety and reducing fabrication costs. A two-person bus seat was selected as the composite candidate and then was designed and compression-molded as a demonstration of the technology. The weight of the composite seat was 50 percent less than the conventional component and could be manufactured in commercial quantities with a 40 percent reduction in cost.
