Fiber Reinforced Polyurethane FRPU Settings

When laser cleaning Fiber Reinforced Polyurethane, we typically begin with a gentle power setup to match its flexible yet tough composite structure. This material absorbs laser energy well, so it clears contaminants quickly without deep penetration. But watch out mid-process—its low heat spread can cause localized overheating, leading to fiber-matrix separation. We've found multiple light passes at steady speeds fix that, restoring the surface evenly for aerospace or automotive parts.
