Production technology of cores for hybrid laminates containing rubber powder from scrap tyres

Future technological and product developments will be measured by their improved resource and energy efficiency, as well as their competitiveness, while allowing for effective climate and environmental protection. In this study, hybrid metal-plastic composites are developed combining lightweight design with high material stiffness. Therein, modifications of the polymer core with rubber powder are used to increase the damping properties for lower structure borne-sound as well as sustain high stiffness and low weight. For the elastomer filling, different polymer base materials are compared. Assuring a gentle processing of the thermal sensitive powder, an energy-efficient one-step direct manufacturing has been successfully developed. (C) 2018 The Authors. Published by Elsevier B.V.
