The timing of the award presentation is perfect: After all, the “Future of Composites in Transportation 2018 Innovation Award” will serve as the culmination of the HyBriLight project, which ended in June and was funded by the German Federal Ministry of Education and Research (BMBF).

Along with industrial partners, the Fraunhofer Institutes ILT and LBF spent nearly four years developing new photonic tools for lightweight production. The highlight of this project is a component known as a hybrid roof bow, which allows project partners to demonstrate how to optimize a hybrid automotive component for series production.

Shorter process time and reduced costs of raw materials

The hybrid roof bow is based on an original component in a BMW 7 Series vehicle. It consists of a fiber-reinforced plastic brace and metallic joining partners, which connect the hybrid roof bow with the chassis. As an alternative to the conventional approach of adhesive bonding and riveting, Fraunhofer ILT developed a new laser-based process that joins plastic and metal by means of adhesion and positive locking.

The company Weber Fibertech optimized the design of the component. Project partners can be proud of their joint innovation, which reduces process times by 70 percent compared to conventional methods, cuts the costs of raw materials in half and integrates multiple process steps into a single, highly automated process.

The HyBriLight exhibition piece demonstrates just how successfully researchers and manufacturers can jointly realize practical, new laser-based techniques for lightweight production. These innovative techniques even surpass conventional approaches in many parameters, such as shear loading (maximum of 50 MPa) and resistance to internal pressure (maximum of 45 bar), which is crucial to tightness.

HyBriLight project

The BMBF project HyBriLight developed photonic tools for lightweight production. More precisely, this endeavor focused on a “process chain adapted for specific materials for cost-efficient and hybrid lightweight production using highly productive laser systems”.
