More than lightweight – groundbreaking innovation for a faster production of cost-efficient and high–performance parts
Composites 4.0 at the service of the industry
At Voith Composites we design and manufacture industry-leading carbon fiber-reinforced polymers (CFRP) - lightweight, strong materials used for a wide range of applications.
With our state-of-the-art Composites 4.0 digital production line, including the award-winning Voith Roving Applicator NextGen, we set the highest standards in CFRP parts manufacturing and are pioneering innovative processes for the future, such as sustainable and recyclable composites.
If your organization operates in automotive, paper industry or other industries, we provide faster, easier and more consistent composites manufacturing, from prototype to scale production to save you time and resources. We leverage our 10 years experience and know-how in filament winding thick-walled products such as CFRP rolls for paper machines to offer highly innovative and performing hydrogen tanks.
Our products
Carbon4Tank is a type IV high-pressure H2 tank made with towpreg filament winding technology.
We design and produce customized composites in a fully automated and digitized manufacturing environment, raising the bar in automotive manufacturing quality.
Carbon4Roll products are lightweight and manufactured with a high-precision filament winding process.

Automotive
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.

We are shaping the future by industrializing and automating clean and fast production of high-pressure hydrogen tanks (700 bar) made with TowPreg filament winding technology. Our CFRP Type 4 tanks are designed for heavy-duty commercial vehicles and offer a sustainable solution at automotive quality standards. The combined expertise of Voith Turbo & Voith Composites results in high-performing H₂ storage systems - The plug & Drive H₂ Storage System. It uses Carbon4Tank and focuses on deep customer integration, sustainability and circularity ovre the product lifecyle.
Industry
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.
Voith Paper uses the reduced thermal expansion behavior of CFRP in its coating units SpeedFlow, SpeedSizer and Dynacoat to increase production quality for the end customer. Conventional coater beams are made of metallic materials and deform strongly due to one-sided thermal loads. This must be compensated for by additional technology such as active temperature control.
When using CFRP coater beam, this additional effort is completely eliminated. Uniform transversal coating profiles during application as well as a constant coating weight under all operating conditions are guarenteed by the thermally dimensionally stable coaster beam. In addition, the complexity of the entire coating unit system is reduced and thus the maintenance effort as well as energy and operating costs are lowered.
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.
