Burrs generated during the machining of Aramid-Fiber-Reinforced Composites (AFRPs) pose a challenge for the production efficiency of aircraft and helicopter housing parts. Existing studies have generally attempted to suppress burrs by referring to delamination suppression methods. In contrast to stratification, burrs are remediable machining defects. As such, a mechanochemical method with burrs trimming technological strategy are implemented to effectively combat burrs. Herein, we clarify the mechanism by which aramid fibers cannot be cut off using analytical and numerical models. In addition, the mechanism of fiber fracture with Modified Polyurethane Reactive Polymer (M-PUR), and development of anti-burr devices (thermostatic adhesive sealed generator) are discussed. Finally, the experimental results show that the reduction rate in burr length is 87%–91% through the mechanochemical method. The method not only opens a new avenue to solve the burr problem of aramid fibers but also builds an interdisciplinary bridge between polymer science and composite machining.
