Machining Kevlar: Challenges, Techniques, and Specialized Tools
Kevlar composites such as K-1226 AFRP offer exceptional characteristics, making them ideal for aerospace, defense, and automotive applications. However, their anisotropic nature and abrasive fibers make machining challenging, often resulting in fiber pull-out, tool clogging, and rapid wear. This article discusses machining strategies, including optimized tool geometry, cryogenic cooling, parameter adjustment, and surface reinforcement techniques (e.g., fiberglass overlays) to improve tool life and surface quality.
