Nature: lightweight construction is increasingly gaining

New, lighter structures
Lightweight construction has long been standard in the car, even if cars are getting heavier for other reasons such as additional safety features.

In machine and plant construction, on the other hand, lightweight construction is gaining in importance.

That is why Hannover Messe is dedicated to the theme of its own leading trade fair.

Why should something be difficult if it is at least as good? Why should you build massively when stable or even better? These questions are at the heart of the “Lightweight Construction” theme at the Hanover Fair.

The fact is: every gram of weight saves energy, material and, in the end, cash. Often the efficiency is even increased.

And the environment also benefits by the way, because in many cases the CO2 emissions are reduced ,at the latest when transporting the now lighter goods.

What is now standard in vehicle construction is also becoming an issue in industry as well as in the energy industry.

Finally, even with modern production plants, speed and stability remain unchanged.

Reason enough for the Hanover Fair 2017 to devote one of the seven individual trade fairs to the topic of “lightweight construction”.

Especially in Hall 6, companies, service providers and research facilities under the motto “Industrial Supply” show their developments in the areas of manufacturing technologies and lightweight construction materials.

A wide field of lectures

Lightweight and light weight structures are the starting point for the Forum “Industrial Supply” in Hall 5.

The focus is on fiber composite materials and multi material approaches.

Further lectures in the course of the fair will be on topics such as “Bionic lightweight construction”, “Light construction in the interior & exterior” and “Innovative barriers and innovation drivers in the value chain of the massive lightweight construction”.

At all, the topic of lightweight construction is multifaceted.

It is not just about replacing the one material with another, but also about a new construction with the help of modern materials.

In many cases, new perspectives, structures and statics emerge when looking beyond the bounds of the box: Nature, for example, was and is a rich source of ideas

Under the keyword bionics, there are many examples of a sophisticated statics that achieve exceptional stability despite the lightest materials.

The theme is not new, as this pavilion shows after the model of a sea urchin.

But the possibilities through new materials are getting bigger and bigger

New possibilities through composites

Visitors to the Hanover Fair will not only be able to directly compare products made of light metals, polymers, composites, foams and material mixes.

But will also gain a comprehensive overview of all possible aspects of the subject on their tour.

For example, the Wilhelm Funke metal foundry in Hall 6, Stand F46, shows how magnesium can be used as a cast material for lightweight construction.

The Karlsruhe Institute of Technology informs you about fiber plastic composites for lightweight construction and Inspire bionics in Hall B16 “Better constructions with bionic inspiration” has been written on the flags in Hall 6, Stand L17.

Self niche items such as “Lightweight construction for furniture fittings” (exhibitors: Ausko, Hall 6, Stand D01) can be found.

Appropriate to the topic, which is often based on several components, several suppliers have often joined together to form an exhibitor association.

An example of this are ten medium-sized suppliers from Baden-Württemberg in Hall 6, Stand F30.

Together they give a good insight into the various possibilities in light construction.

The C & C Bark company is presenting a hot chamber die casting process, which makes magnesium parts even easier than before.

The company Weippert offers screws and nuts made of high strength, glass fiber reinforced plastics and Gaugler & Lutz specializes in core materials such as foam components, which play an essential role in lightweight construction.

Example of vehicle construction


A realistic example of how lightweight construction conserves resources in the automobile industry and at the same time increases safety is presented by scientists from the Chemnitz University of Technology in Hall 2, Stand A38.

The researchers have, among other things, more than halved the weight of the so-called “Throughput”, which in many cars on the back bank allows the passage of long objects.

Production costs also fell by around 30% compared to the steel variant.
