Hexcel’s automotive sales development manager, Denis Granger, plans to give a presentation on new materials and adhesive for hybrid structures in the automotive industry at the Composites Europe show.

He will be joined by Etienne Marrier, R&D engineer at St Jean Industries, who worked with Hexcel to develop a concept suspension knuckle in which the aluminum structure is stiffened with carbon fiber prepreg stacks. According to the companies, the hybrid solution results in a 25% increase in part stiffness compared to the aluminum-only suspension knuckle, with only a very slight increase in part volume. The CFRP/aluminum hybrid version also fits into the existing space restrictions, allowing just one aluminum part design to be used across all models in the range. CFRP increases the maximum strength before failure of the part, with optimum load distribution determined by Hexcel’s FEM calculations. The prepreg stacks were bonded to the aluminum with a film adhesive for the high volume processing of metal/CFRP hybrid structures.

The presentation will take place during the Automotive session at the Lightweight Technologies Forum on Thursday 21 September at 1 pm.
