Assessment of the effect of processing parameters on peel failure of laser-assisted automated fiber placed thermoplastic composites

In this study, thermoplastic composites are fabricated using laser-assisted automated fiber placement, focusing on the influence of compaction force, roller head speed, and temperature. Employing wedge peel testing, digital and electron microscopy, and probabilistic machine learning, the research examines how these parameters affect mechanical performance and failure. Key observations include increased bonding area and peel force with higher processing temperatures, while greater compaction force introduces more variability in bonding and peel strength. Roller head speed shows minimal impact. The study effectively links processing parameters with wedge peel failure, illustrating the complex interactions in composite material behavior.
