More than lightweight – groundbreaking innovation for a faster, easier and more consistent production of CFRP 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 aerospace, 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.
Carbon4Tool stack is a multi-layer prepreg system for CFRP tooling, supplied in pre-cut tiles.
Carbon4Stack is a prepreg CFRP stack suitable for structural, semi-structural visual, and painted applications.
Carbon4Roll products are lightweight and manufactured with a high-precision filament winding process.

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.
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.
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) NextGen
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.
Filament Winding Process
Voith Prepreg Winding (VPW)
Different curing processes are possible, depending on requirements: (High pressure) resin transfer molding, wet compression molding or prepreg compression molding.
