Glass Fiber Reinforced Polymers GFRP Laser Cleaning Settings

We've found that GFRP's embedded glass fibers in a polymer matrix demand careful laser setup right from the start to avoid delamination. Start with lower power levels and slower scan speeds, since the fibers can channel heat unevenly. This composite nature sets it apart from uniform metals—heat builds up in the resin quickly, risking cracks. We typically use multiple light passes with good overlap to gently remove contaminants without stressing the fibers. Watch for surface blistering; it signals overexposure, so dial back energy if you see any bubbling. In our experience, this approach restores the surface cleanly for aerospace parts while preserving strength.
