A new ultra-lightweight sandwich structure for the cars of tomorrow
The electric car was one of the featured attractions at this year's Paris Motor Show. Launched to coincide with the show, the new inrekor technology for car chassis manufacturing could play a crucial role on this market by lowering the weight of cars by 30 to 40%, with weight considerations being such an important issue for electric vehicles.
more the weight of the vehicle. This lighter structure reduces the electrical power requirements for driving the vehicle, which in turn offers longer battery life. An inrekor chassis has already passed structural tests and crash tests carried out respectively by the Warwick Manufacturing Group (WMG) and the Motor Industry Research Association (MIRA), designed to check its full compliance with the strict requirements of the automotive industry. It obtained the same performance levels as a 5-star NCAP structure, for a 34% lighter weight. Furthermore, it has no flash point, its materials cannot ignite and they will only burn when heated to in excess of 180° C. Inrekor passes all tests with flying colours: it is lighter, easy to manufacture and kinder on the environment.

nrekor is an ultra-lightweight sandwich structure with a core of expanded polypropylene that is used in the automotive industry for the manufacturing of bumpers, door frames, and so on. This dual-material combination offers an exceptional strength-to-weight ratio, making the structure extremely strong for a significantly reduced weight when compared to traditional structures.

benefits include its light weight, a reduced investment, its design versatility and its safe performance characteristics. Inrekor is an ultra-lightweight sandwich structure, consisting of an expanded polypropylene ARPRO® core between two aluminium panels. This combined structure offers an exceptional strength-to-weight ratio which makes it extremely strong, and gives the automotive industry an opportunity to reduce spectacularly its impact on the environment.

An innovative technology

Inrekor technology combines recognised adhesive technologies with standard industrial materials available worldwide in order to create an ultra-lightweight sandwich structure. This makes it possible to design ultra-light chassis for massproduced vehicles. Its principal

A flexible solution
The innovation of inrekor technology also lies in its extreme flexibility and its design friendliness. The various elements of the chassis slot together

Significant weight reductions

An inrekor chassis and the weight savings it brings with respect to the car’s other components would translate, for a standard family-sized electric car, into a weight reduction of 30 to 40%: in other words, from 1.6 tonne to less than 1 tonne. Unlike traditional monocoque structures, the inrekor chassis incorporates the electric battery in its very structure, thus reducing all the
