Abstract
A vehicle interior panel includes an engraved image at a decorative side of the panel. The image is produced by selectively removing a film layer from a compression molding to expose an underlying surface of a substrate layer in a desired pattern. The substrate layer is formed from a composite material including natural fibers. A laser beam is configured to remove the film layer and to cauterize the natural fibers along the pattern. The cauterization has an anti-aging effect on the natural fibers by increasing color stability and water resistance of the exposed composite material.
