A new, continuous manufacturing process to make high molecular weight, high thermal conductivity polyethylene fibers and sheets was developed to replace metals and ceramics in heat–transfer devices. Project innovations included use of a gel-extrusion process and subsequent hot drawing to assist in sheet formation. Because polyethylene density is 35% less than aluminum, the new materials and process steps developed as part of this project could generate fuel savings for transportation applications
