Lightweight Construction for the Automobile Generation of the Future

14.10.2013
One of the main challenges of our times is to use limited resources efficiently.

And the decisive factor for automobile construction of the future is to reduce the weight of the car. The Volkswagen AG is working together with the Laser Zentrum Hannover e.V. (LZH) and other partners on developing an innovative laser process for automated cutting of CFRP components, to make it possible to use this lightweight material for mass production.

Lightweight materials, which have both high strength and stiffness, are the materials for automobile construction of the future. This is due to safety reasons, which cannot be sacrificed in order to reduce weight.

Carbon fiber reinforced plastics (CFRP) have the characteristics that are needed. However, CFRP is a challenge in production technology, and currently, CFRP components are mainly used in the sports car sector and in small batch automotive production.

If cars based on CFRP are to be mass produced, then automated production technologies for cutting this lightweight material must be developed. Conventional technologies such as milling or waterjet cutting have process-based disadvantages, such as high tool wear or handling of water and abrasives, which cannot be solved technologically.

In the current joint project HolQueSt 3D, seven partners from industry and science, under the leadership of Volkswagen AG, are working together on developing a process for 3-D high-performance laser processing of CFRP lightweight structures. In comparison to conventional technologies, lasers can be used for non-contact, high-precision processing without tool wear, and simultaneously the process has high reproducibility and flexibility. Up to now, due to high temperatures, laser processing of CFRP causes damage in the processing zone. The main hurdles for using laser processing for CFRP are at present an incomplete understanding of the process, and the lack of sufficiently developed processes.

Based on a new, fiber-guided, high performance laser with pulse lengths in the nanosecond range (Trumpf Laser GmbH + Co. KG), the LZH is developing both a process especially geared towards CFRP applications and an optimized process monitoring system. A further obstacle to the use of lasers in lightweight construction is the process-based generation of particles and gasses, which are partially hazardous to health. Together with Jenoptik Katasorb GmbH, the LZH is working on a remedy, by finding a suitable method for treatment and filtering, based on previous characterisation of the process emissions.

These concepts should be used to provide large-scale CFRP processing adapted to the demands of the automobile industry. Thus, resource efficient, lightweight construction concepts could soon find their way into today’s automotive generation.

HolQueSt 3D is financially supported by the German Ministry of Education and Research (BMBF), within the framework of the funding initiative “Photonic Processes and Tools for Resource-Efficient Lightweight Construction”, with funding of approximately 4 Million Euros from a total amount of 7 Million Euros for the whole project. Project partners are Volkswagen AG, Jenoptik Katasorb GmbH, Trumpf Laser GmbH+Co. KG, Invent GmbH, KMS Automation GmbH, TU Clausthal and the Laser Zentrum Hannover e.V.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
