Abstract

A surfacing material that is capable of ultraviolet (UV) protection and self-releasing from a mold surface. The surfacing material is a multilayer structure composed of a curable resin layer laminated to a self-releasing layer. The surfacing material is designed to be co-cured with a composite substrate, for example, a prepreg layup. After co-curing, the composite part surfaced with the surfacing material is releasable from the mold surface with ease. The self-releasing layer functions as a UV blocking layer until the cured composite substrate is ready for painting. When the self-releasing layer removed, a paint-ready surface is revealed. Such surface does not require any surface preparation prior to painting.
