Manufacturing and Characterisation of High-strength Plastic-metal Hybrids

Abstract

WORLDWIDEManufacturing and Characterisation of Highstrength Plastic-metal Hybrids Metals and plastics have long since been rival materials when it comes to "plastic substituting metal". Well-known exceptions to this rule include insert and outsert technology. This is primarily based on integrating locally arranged elements of the single material component into associated structures of the other material.

Research Progress on Characterization and Regulation of Forming Quality in Laser Joining of Metal and Polymer, and Development Trends of Lightweight Automotive Applications

“…The weight of the composite B pillar was reduced by 27.7%, and the side crash resistance was improved. Hoffmann et al [28] explored the integrated molding of PA6-GF60 and aluminum composite material by examining its application in the cockpit beam. With the aim of ensuring performance requirements, a variety of lightweight designs can be achieved for similar components by reasonable combination of connection processes, materials, and structures.…”

Hoffmann et al [28] explored the integrated molding of PA6-GF60 and aluminum composite material by examining its application in the cockpit beam. The application of metal and polymer hybrid structures in vehicle bodies is not only limited to the requirements of component performance and weight, but also involve other functional properties of the components, such as assistive enhancement, passive safety, aesthetic comfort, etc.…”

The effect of methods of surface treatment of metal elements on their surface free energy, with a view to the formation of polymer-metal hybrid elements

“…Injection molding technology enables the production of relatively complex hybrid elements through the joining of a metal element to a polymer in an injection process over a single technological cycle [9]. To improve the adhesion of the polymer to the metal element, various methods of surface treatment are applied: chemical or electrochemical treatment of the outer layer of the metal [8], laser structuring of the surface of metal elements to produce roughness enabling the mechanical anchoring of the injected polymer [10], or the use of an intermediate coupling layer [11].…”
