More than lightweight – Realize your vision in carbon fiber construction.
The unique combination of engineering competence and production know-how, as well as the outstanding characteristics of fiber composites, creates maximum value for you.
We design and produce dry and pre-impregnated customized stacks based on your requirements. With our internally developed direct fiber placement and preforming technologies, we achieve near-net-shape fiber layup with local reinforcements as well as reduce scrap to a minimum or eliminate it completely. After fiber placement, forming of the stacks can be realized by stamp forming or double-diaphragm process.

Composite rolls and shafts are manufactured with a high-precision filament winding process. The fiber is pulled from the coil, led through a resin bath and wound onto the mandrel. We develop rolls with lengths of up to 13 m, diameters up to 1.2 m and wall thicknesses of up to 70 mm. We support you with adhesive bonding, bold construction and customer-specified force introduction solutions for high loads and torques.

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
We manufacture CFRP parts with a Class A surface suitable for inline e-coating and painting processes. The blanks are produced with our self-developed preform technologies VRA and VPW.
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.
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.
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.
Due to its high specific stiffness and strength, CFRP is very well suited for use in drive shafts. The performance of the material often allows a reduction in the overall costs of the system; the one-piece design avoids cost-intensive bearing points. Due to the favorable ratio of stiffness to density, CFRP drive shafts achieve a significantly higher critical bending speed than steel shafts.
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.
