Abstract:

An innovative Rapid Automated Induction Lamination RAIL process has been developed that can fabricate fully consolidated 8-ply AS4polyetherimide PEI laminates in high volumes. The process relies on induction-based rapid volumetric heating for multilayer consolidation at very rapid rates less than 30-s cycle times, while maintaining high quality 1 voids. Pull translation of mechanical properties has been achieved in comparison to baseline processes, such as autoclave and vacuum debulk with an order of magnitude increase in throughput. The RAIL process has the potential to be integrated with thermoforming for high-volume production of net-shape carbonthermoplastic parts.
