Heavy Duty Vehicles


In the 1960s, Molded Fiber Glass blazed the trail of composite material conversion for the commercial truck industry. Since then, many OEMs have realized that they can use composites to redesign trucks in order to increase fuel efficiency and increase performance. These materials are being applied to the next generation of environmentally friendly trucks, buses and even semi-trailers. Due to their high strength and low weight, these heavy duty vehicles are able to carry larger payloads, which is important in an industry that abides by weight restrictions put in place by the federal highway system.
