The rear wall is customized for the Audi A8 and displays the largest component of the occupant call. With its optimized fiber layup with 6 to 19 carbon fiber layers, it significantly contributes to the torsional rigidity of the vehicle. The rear wall is manufactured in Voith Composites' in-house developed production line and is designed to manufacture approximately 65,000 components each year. At JEC World 2018, we received the JEC Innovation Award 2018 for this digital production line.digital production line wins JEC Award 2018
Thanks to their outstanding surface quality (no print-through) and high drapability, our Carbon4Stack and Carbon4Visual products are also being used for Class A and visual applications. The usually required rework can be drastically reduced or even eliminated when working with our stacks.
Voith Composites works on the next generation of hydrogen high pressure (700 bar) vessels for fuel cell electric vehicles (FCEV). Nowadays, reducing process costs in combination with new vessel concepts is of decisive importance. At Voith Composites, the finite element method (FEM) and winding simulation, as well as accompanying quality management during development, ensure qualitative results. Fast development loops due to the short distance to the test facilities also support this.
Guide rolls made of steel are often operated above their capacity limits, which can result in vibrations and thermal deformations. Unlike steel, the strength and rigidity of CFRP rolls can be adapted to the specific requirements without altering the installation space. Moreover, the much lower density ensures a significant weight reduction. CFRP components also offer a range of other benefits, like low thermal expansion or excellent running properties. Thus, composites are typically used for various guide rolls along the entire paper manufacturing process in the paper industry.
In the papermaking process, the SpeedSizer AT improves the paper characteristics, penetration and surface coverage in a targeted fashion. Classical applicator heads are built from stainless steel, steel or cast iron. Thermal influences cause deflections at the applicator head, which can result in poor CD profiles producing coated papers. The use of CFRP achieves optimal film application with outstanding CD and MD coat weight profiles throughout all operational conditions. With a CFRP beam, the systems needs no temperature-controlled heating system, which ensures dimensional stability at all. The results are optimal profiles over the entire life cycle and lower energy consumption.
In cooperation with Voith Turbo, blades for the Voith Inline Thruster (VIT) were manufactured from CFRP. This set a new standard for the coating quality of anti-cavitation coating. Moreover, the blades are characterized by a high UD proportion.
Voith Composites designs and produces components for the aerospace industry, including seat components, tanks, linings, overhead storages and ducts. With the use of carbon fiber, the shown duct segment is temperature-stable, high load capable and incredibly lightweight.
Our preforming technologies
Voith Roving Applicator (VRA)
The method uses cost-effective raw materials such as untreated rovings and binder powder to produce a near-net-shape dry stack as part of the fully automated preform production. The VRA produces components efficiently, inclusive of individual fiber distribution and local reinforcements.
