Production projects

From prototype to successful serial production

The process is based on long fiber thermoplastic technology, which gives you considerable flexibility in terms of design and structure. Glass or carbon fibers are added to the thermoplastic matrix material via our own compounding plant; owing to the gentle production process, these fibers remain intact for much longer than is the case, for instance, with conventional injection molding. The base material alone results in improved strength and stiffness of the parts.

If necessary, continuous (endless) glass or carbon fibers – which increase the strength of a part locally so that it fulfills crashworthiness requirements – are incorporated into this basic LFT structure as structural reinforcement.

Large-sized parts, as a substitute for sheet metal parts or sheet metal shell structures, can be economically produced using this technology. Developers also have the option of integrating functional elements directly into the process, enabling certain installation and testing steps to be eliminated.

Tailgate – Smart BR 451

This functional structural part – which is also a visible part with its grained surface – was manufactured in plastic using the E-LFT process from what were originally two aluminum and injection molded variants.
Advantages: 25% stiffer than the original metal parts as well as lighter and more economical.

Water jet drive

Abrasion due to sand was taking its toll on the original metal drive – no problem for our long fiber-reinforced plastic. All components of the water jet drive are manufactured using a family mold in a single compression step – another economical solution.

Third seat row of the Daimler E Class

Cargo floor and third seat row in one: this part was manufactured with a shell-type structure using E-LFT technology, resulting in very high stiffness. The reduction in weight – and hence costs – tipped the scales in favor of our lightweight design technology.

Development projects

Application-oriented research & development projects

The aim of Weber Fibertech’s research and development activities, with the focus on lightweight design, is to promote lightweight design technologies through application-oriented development projects.

The upcoming trend towards electric mobility in the automotive industry has added further impetus to our specialization in lightweight design. Fiber composites will play a crucial role in tomorrow’s world. The direction is clear: our engineers will be called upon to apply their expertise in material mechanics, simulation, structural mechanics and bonding and joining technologies. Together with our customers, we will endeavor to develop lightweight, structurally stable parts with a high level of integration.
