Reactive polyamide-carbon fiber composites promise lower cost


BASF (Ludwigshafen, Germany) and the SGL Group (Wiesbaden, Germany) plan to jointly develop a composite material based on a reactive polyamide system and suitable carbon fibers, thereby enabling the cost-effective production of thermoplastic carbon fiber-reinforced composites.

The material system is intended for use in the T-RTM (Thermoplastic Resin Transfer Molding) process as well as the reactive injection molding (RIM) process, and reportedly permits considerably shorter processing cycles than conventional thermosetting RTM. The switch of the material system to these faster processing techniques will play a major role for the entry of light and high-strength structural components made of carbon fiber composites into automotive mass production.

As a leading producer of polyamide and caprolactam, a precursor of polyamide, BASF is contributing its competence in the development of new polymer matrix systems. The SGL Group is utilizing its material expertise along the carbon fiber value-added chain and in high-temperature processes....
