Cast hybrids meet stiffness challenge

摘要

German company Handtmann Elteka has developed a polymer-metal hybrid manufacturing technology for lightweight, high stiffness engineered components. The technique uses a modified version of Evonik's Laur-amid A polyamide 12G material, which is cast and polymerised at low pressure around a foamed aluminium core. The metal core can have a closed or open cell structure.
