Filament winding
Filament winding is a process in which continuous fibre wetted with resin is laid on a rotating mandrel at a programmed angle. The winding angle decides stiffness and strength: small angles strengthen bending, angles close to 90° resist internal pressure. Tubes, shafts, profiles and tanks are made this way.
Key parameters
| Typical volume | from tens to tens of thousands of pcs/year |
| Shapes | rotational and similar, profiles |
| Winding angles | programmed, usually approx. 10–90° |
| Surface | smooth inside (mandrel) |
| Fibres | carbon, glass, aramid, basalt |
| Production | with partners, under Carbon Design supervision |
Typical, indicative values – they depend on the geometry, material and requirements.

Wound profiles in the UL-CompPro project
In the UL-CompPro project, run with East 4D Carbon Technology GmbH in the AMULET (1st call) programme, we are developing ultralight helicopter skids. The structure combines filament-wound profiles with forged carbon connectors – each element is made with the process best suited to its function.
We have also developed a method for carbon profiles with a variable outer shape and a variable section. When a profile does not have a constant diameter, we choose the process for the geometry and loads – filament winding is one of the options.
When to choose it
- The part is a tube, shaft, profile or tank
- You need precisely designed fibre angles for the loads
- Repeatability and automation matter
When another process is better
- The shape has concave areas and cannot be wound – RTM, compression moulding or forged carbon
- A smooth moulded outer surface is required – extra finishing is needed
Questions and answers
Do you make variable-section profiles?
Yes. We have developed a method for carbon profiles with a variable outer shape and section. We choose the process for the geometry and loads of the profile.
What parts are usually filament wound?
Drive tubes and shafts, arms and beams, structural profiles, covers and pressure vessels, including hydrogen tanks.
