Voith Composites

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.

      Audi A8 CFRP rear wall

      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.

      Carbon4Roll: High quality carbon fiber rolls for paper machines

      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.

      CFRP Applicator Beams

      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.

      CFRP blades for the Voith Inline Thruster

      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 Roving Applicator (VRA) NextGen

        Instead of applying a binder like the VRA from the first generation does, the VRA NextGen can impregnate the resin directly into the fibers. This further streamlines the process chain and makes it easier to handle workpieces – especially if they are manufactured within the same production line.

        Voith Roving Applicator (VRA)

        Voith Roving Applicator (VRA)

        The Voith Roving Applicator (VRA) is a fully automatic direct fiber placement machine with high, scalable lay-up rates. At JEC World 2017, the VRA technology won the JEC Innovation Award.

        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

        Filament Winding Process

        Filament Winding Process

        The Filament Winding Process enables high precision for rolls and shafts: the fiber is unwound from a roving spool, led through a resin bath for impregnation and then wound onto the mandrel. The wound laminate is tempered in an oven to let the resin react and cure what gives the composite structure its stiffness and strength. Finally, the mandrel is pulled from the composite roll.

        Research and development

          We continue to enhance our expertise in numerous development projects – on our own and with research and industry partners.
