The pultrusion of thermosetting structures has long been state-of-the-art, and the pultrusion of thermoplastics in combination with braiding or winding techniques now opens up entirely new areas of application. To give an example, it facilitates the multi-axial braiding of media-resistant polymer tubes to form high-performance pipes that can be subjected to internal loading. Depending on the specific project requirements, it is now possible to process any material from low-cost GF/PA to high-performance CF/PEEK – continuously and with a high degree of automation. Pultrusion also enables the embedding of axial fibre reinforcement with minimal undulation, thus facilitating the production of flexurally rigid pipes or shafts.
The process at a glance
- Continuous production, high degree of automation (≫ 1 m/min)
- Thermoplastic matrix systems ranging from PA to PEEK
- Embedding of axial reinforcement with minimal undulation
- In-process integration of media-proof liners
- Integration of additional elements during subsequent forming process
- Outstanding mechanical characteristics, minimal porosity
Pultruded thermoplastic profiles
The use of thermoplastic polymers in combination with braiding significantly expands the possibilities offered by pultrusion. Examples include the integration of media-resistant interior liners, the retrospective, section-specific shaping of profile contours and the straightforward welding of individual segments.
