Lightweight Design Automotive Supplier Focuses on Lightweight Structural Design with Fiber Plastic Composites

Editor: Nicole Kareta

Lightweight structural engineering based on fiber-reinforced plastics is replacing heavy metal solutions in body-in-white and battery applications. In addition, the technology offers significantly better design and integration options. These lightweight designs particularly support the strengths of alternative drive systems. Röchling Automotive is intensifying research and development in this area.

Engineering plastics serve as the basis for lightweight solutions. Röchling's high-performance plastics are combined with other materials as required. Multi-material design produces components that are superior to classic solutions. Peter Dill, Director Product Portfolio Global, summarizes the advantages: "In lightweight structural design, plastics are the basis for tailor-made modification of material properties. This opens up numerous possible applications. The lower weight and the possibility of integration offer a welcome opportunity to reduce costs."

Dill explains this using the example of Röchling Automotive's front-end carrier: "Through functional integrations, we reduce the quantity of individual parts. We can directly integrate and install lamps, sensors and active grille shutters at factory. This makes handling easier and minimizes production costs." The lower weight of the components extends the range of electrically powered vehicles and reduces fuel consumption and CO2 emissions, Dill added.

In addition, Röchling Automotive is conducting intensive research on further increasing strength and stiffness through continuous fiber reinforcement. In so-called tape technology, additional reinforcing elements are inserted into the components along the load paths. These "tapes" consist of extremely thin, very long glass or carbon fibers embedded in a plastic matrix. The associated local reinforcement ensures optimum use of the material. The material can be subjected to high mechanical stresses. At the same time, the cost of tape technology is comparatively low.

For Tobias Eisele, Vice President Sales & Marketing Global, the development of structural lightweight competencies at Röchling Automotive is a logical step: "We have already shown in various projects what is possible with lightweight design today and the importance of structural lightweighting will continue to grow. By expanding our expertise in this area, we are focusing on a technology of the future."
