TWO-PIECE LIGHTWEIGHT METAL-POLYMER HYBRID STRUCTURES

摘要

An approach to designing lightweight metal-polymer composite structures in a manner that decomposes the structure into at least two parts. In one specific embodiment, the approach is a manufacturing process for a vehicle that includes attaching an impact beam to a vehicle structure. The process includes providing a vehicle structure including a back plate of the impact beam being made of a suitable material, such as a metal, that can withstand high temperature processes. A front part of the impact beam including a front plate and a polymer core is attached to the back plate. The back plate is designed to provide structural integrity that allows the vehicle structure to go through the high temperature processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes. The back plate is also designed to provide desired functional characteristics of the beam.

1. A method for manufacturing a vehicle, said method comprising:
providing a vehicle structure including a configuration of metal structural elements, wherein at least one of the structural elements is a back plate that is part of a beam; performing one or more processes to the vehicle structure that requires high temperature, wherein the back plate is designed to provide structural integrity that allows the vehicle structure to go through the one or more processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes; and mounting a front assembly that is part of the beam to the back plate after the high temperature process, where the front assembly includes a front plate mounted to the back plate and a polymer insert positioned between the front plate and the back plate, wherein the back plate is also designed to provide desired functional characteristics of the beam.
