Braiding is currently the most efficient and variable preforming process for hollow fibre-reinforced profiles. It allows almost any reinforcement fibres – including carbon fibres, glass fibres or impregnated tapes – to be layered onto contour-specific braiding mandrels at very high speed and infiltrated with the matrix material with minimal waste (similar to the RTM process). Fibre orientation along the component axis is highly variable and can therefore be adapted to the specific loading direction of the target component. The braiding process facilitates the cost-efficient production of extremely lightweight hollow structures.

Our facilities (used as part of our cooperation with the Institute of Lightweight Engineering and Polymer Technology (ILK) of TU Dresden)

  • Vacuum pumps
  • Pressurized curing vessels
  • Cutting table for the preparation of reinforcement textiles and vacuum materials

Drive shafts with integrated load application elements

In the case of drive shafts braiding offers the following advantages:

  • Load-conform fibre alignment in sections of the shaft where loads are or are not applied
  • Fully automatable production (braiding + infiltration)
  • Rapid production, even in the case of thick-walled structures
  • Creation of undercuts (thus ensuring true-to-form load transfer)

Technological development

The variability of the braiding process is almost unlimited. In-house developments such as the variable braiding eye in the right-hand picture make it possible to further increase the degree of component complexity. Even hub-like elements can be produced (see left-hand picture).
