Tow Wrinkling Mechanisms and Mitigation in Automated Fiber Placement

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : December 17 , 2025 Abstract Automated Fiber Placement (AFP) enables high-rate manufacturing of complex composite structures through precise deposition of narrow prepreg tows along curved paths. However, steering-induced defects—particularly tow wrinkling—remain a critical limitation to part quality and productivity. Tow wrinkling primarily arises
