Abstract
A cosmetic part is formed via compression molding in a single molding operation with no post processing by forming an assemblage of feed constituents, wherein the assemblage includes plural fiber-bundle-based preforms and one or more resin-only constituents, the latter configured and positioned as appropriate to create resin-rich cosmetic layers where desired on the part.
