Year of construction of the first own CFRP shafts


Drive shafts produced so far for maritime applications


Composite-Drive shafts for ships

Our customers in the marine sector trust our expertise in this field for about 20 years now. With DYNEXA, AVANCO Composites has established itself as a strong and reliable partner for composite drive shafts for small and large ships.

In the field of maritime shipping, whether for private shipbuilding, sports regattas or sea transport, sustainability and increased efficiency are playing an increasingly important role. In order to cross the seas in a resource-saving way, the requirements in terms of lightweight construction, durability and increased efficiency are constantly growing. More and more components, from drive shafts to frames, masts, hoists and many other components, are being replaced by composite solutions or supplemented by a hybrid design.

And this is exactly where the lightweight construction specialists at AVANCO Composite come in: With this objective in mind, we develop fully composite or hybrid solutions with our customers according to the application. Our focus here is on sensible and economical lightweight design, taking into account all materials. But it is not only the conception and development of individual components that is important to us, we also provide our customers with support from the prototype phase right through to series production.

Composite-Solutions for marine drive systems

Since the mid-1990s, DYNEXA and its partners have been manufacturing carbon shafts for use in fast ferries (mono-hull and catamaran), luxury yachts, marine and cruise ships, as well as for tugs, pilot and hydrofoil boats as well as many others. We are the specialist for CFRP spacers, and thus the development partner and supplier for manufacturers of marine powertrain systems. With more than three thousand large shafts delivered with lengths up to 12 m and diameters up to 800 mm for the transmission of torques of up to 800 kNm, impressively underline our market-leading position.

70% lighter than conventional shafts

Regardless of whether it lies between motor, transmission or water-jet, the shaft needs to be perfectly tuned to its operating environment.  Our CFRP material enables spacers with particularly high critical speeds, permitting the spanning of great lengths without the need for intermediate bearings, or a reducing the number of intermediate bearings along the power train. Our X-SHAFT is up to 70% lighter than a conventional shaft. The ratio of torque stiffness to bending stiffness is perfectly adapted for the individual application. CFRP shafts reduce sound and vibration through their damping properties as well as offering corrosion-resistance.  They have very long life cycles because they are wear and maintenance-free. If desired, we can provide you with integration services for additional interfaces (e.g. bulkhead wall seals), special versions (e.g. with a flame retardant coating) as well as the dimensioning of the joining technology which is required to withstand the loading interface to the metal flange.

High production standard and certified quality management

Our X-SHAFTs meet the requirements of the major classification societies, for example, Germanischer Loyd (GL), Bureau Veritas, Det Norske Veritas (DNV) as well as any other required classification.
