New Publication: Frictional Properties of Towpregs in CFRP Filament Winding Processes

Our latest research, conducted by Benedikt Bergmann and Dr.-Ing. Jens Schlimbach, has been published in the European Journal of Materials. This study investigates the frictional properties of towpregs used in filament winding processes, a critical aspect of carbon fiber reinforced plastics (CFRP) manufacturing.

Key Findings:

• Friction Forces: The study reveals that increasing fiber forces and process speeds result in higher friction forces, which are essential factors to consider for ensuring the quality of wound components.
• Comparative Analysis: Our research highlights the varying friction behaviors between dry carbon fibers and different towpregs, providing valuable insights for optimizing manufacturing processes.
• Material Aging: The research also shows that the aging of prepreg materials significantly influences the friction coefficient, underscoring the importance of material condition in production outcomes.
