Polyester Resin Composites Laser Cleaning Settings

When laser cleaning polyester resin composites, I've found starting with a gentle pass works best. These fiber-reinforced materials differ from plain plastics because they're layered for strength, so the laser clears surface grime without delaminating fibers. You'll notice their low heat spread compared to metals—keeps the base intact. Adjust the beam to skim lightly at first. This tends to restore the smooth finish nicely, especially in aerospace or marine parts where corrosion hides underneath. I've seen it shine up wind turbine blades effectively. Move the scan steadily across the surface. Unlike denser composites, these expand little under heat, avoiding cracks. But watch the edges. End with a final check—too much dwell can yellow the resin, so pull back power if you spot any haze.

Power Range

Amplifies damage risk in Pulse Width and Fluence. Keep low to maintain safety margins.

Spot Size

Same power in a smaller spot creates much higher energy density.

Pulse Width

More power means higher peak intensity. Too much can damage the material.

Pass Count

Using more passes means you can use lower power and still get the job done.

Fluence

Higher power delivers more energy per pulse, removing more material.
