摘要:A method of making glass fiber mat reinforced RIM panels wherein glass fibersare kept away at a distance from the panel surface in a precisely controlled manner toavoid fiber readout defect. The method is carried out by molding glass fiber mats in amatched metal mold where at least one of the interior mold surface is etched withequally spaced, closely packed minute pockets or valleys of truncated pyramid shaped.Fiber glass mat reinforced panels thus produced have a textured panel surface with amultiplicity of minute truncated pyramid like protuberances. Glass fibers are excludedfrom such protuberances to produce a panel surface without the fiber readout defect.
