Manufacturing of reinforced profiles by means of combined continuous and discontinuous composite extrusion

Abstract Discontinuous composite extrusion allows the partial embedding of cylindrical, spherical or rectangular reinforcing elements into an aluminum profile. However, continuous composite extrusion allows the embedding of wires or flat ribbons over the complete profile length. In recent investigations, a new die concept has been developed to combine the advantages of both processes and manufacture a semi-finished product for a subsequent hot forging process. The combination generates new challenges regarding the die design. For this reason, the material flow of the concept was analyzed by FEM. Subsequently to the manufacturing, the die was experimentally tested and the embedding quality was analyzed
