WOT researchers significantly involved in the development of an intrinsic hybrid composite

Scientists from the three professorships of Solid Mechanics, Materials and Surface Engineering and Materials Science at Chemnitz University of Technology and the Fraunhofer Institute for Machine Tools and Forming Technology IWU Chemnitz have designed a so-called intrinsic hybrid composite for crash-loaded structural components and produced it in a near-series production process.

The composite counteracts the deficit of fibre-reinforced materials in absorbing only little energy in the event of a crash. In the newly developed concept, fibre-reinforced plastic panels were therefore designed to be crash-proof by means of metallic inserts. However, this was done particularly against the background of resource-efficient production. Thus, previously sequential process steps could be combined in one process step by means of novel form-fit elements, whereby the form-fit elements straighten up during the generation of the macroscopic component geometry due to the effect of a tensile force from the insert and anchor firmly in the plastic component. The resulting form fit significantly improves the force transmission between the metal and plastic components. In addition, the metallic insert is coated in a sol-gel process suitable for large-scale production, which at the same time reliably prevents contact corrosion and improves the adhesive bond between the metal and plastic.
