TP pultrusion

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
