Drive shafts

Carbon fiber brings significant weight reduction into the drivetrain and reliably transfers the torque generated by the powertrain from the transmission to the rear wheels.

More details

The shafts used for rear-wheel and all-wheel drive vehicles often bridge substantial distances before they reach the differential gear boxes, this often necessitates the use of intermediate bearings. The high specific stiffness of CFRP enables our X-PROP shafts to become significantly longer without the need for intermediate bearings. The reduction of weight (and the eliminated costs of extra hardware) through the omitted bearings and joints, represent a major part of the added value that our carbon shafts offer. Similar conditions are also applicable to many applications for the commercial and special vehicle industry. We manufacture composite propeller shafts in automotive serial production, focusing on meeting the requirements of our OEM and Tier 1 customers, which include:  Minimum shaft weights, patented crash concepts, defined load capacity, reliably scalable force introduction processes, the use of cardan-shaft components from leading manufacturers, while maintaining the smooth integration of the CFRP shaft into the vehicle in terms of performance, installation space, acoustics (NVH) and costs.

Rotor- and stator sleeves

Our rotor bandages offer a range of benefits that significantly reduce the air gap between rotor and stator.

More details

They enable the compensation of centrifugal forces and thermal expansion, leading to improved energy efficiency and power output. Thanks to their outstanding mechanical and thermal properties, they are also suitable for the highest motor speeds. Dimensional accuracy in the circumferential direction is ensured by adjustable thermal expansion. Additionally, the low conductivity of the composite material minimizes magnetic losses compared to metallic solutions. Improved stator cooling is also achieved, while the bandage effectively seals the rotor from the coolant. Additionally, the use of thin-walled shells (~ 0.2mm) enables particularly efficient design.

Stabilizers

Our stabilizers offer flexible adjustment of torsional and bending stiffness through the selection of fibers and winding angle.

More details

This enables effective weight reduction in suspension systems. Due to the use of CFRP, our stabilizers also stand out for their excellent damping properties. Their outstanding fatigue behavior and resistance to corrosion guarantee long-lasting performance and reliability in various applications.

Profiles

Our profiles come in a wide variety of shapes, including C-, Ω-, T-, and I-beams, to meet the demands of diverse applications.

More details

In addition, we offer cut-to-size parts and organ sheets for postforming, as well as tailor-made layer structures for specific applications. Our products are particularly well-suited for high-volume applications due to their fast manufacturing speed. They are thermoformable and weldable, further enhancing their versatility in application. Furthermore, they are characterized by high dimensional accuracy and low porosity (< 0.5%), enabling reliable and precise processing.

Thermoplastic pressure
vessels

Our thermoplastic hydrogen tanks enable efficient one-step processing outside the autoclave.

More details

They are made of durable and impact-resistant materials that seamlessly integrate with existing lining material concepts. By using thermoplastic polymers, our tanks benefit from a sustainable advantage through their recyclability. Additionally, optimized winding patterns enable weight-saving opportunities without compromising stability. Our production processes include integrated quality assurance and production parameter recording to ensure the highest standards and maintain consistently high quality.
