COMPOSITE ARTICLES AND A PROCESS FOR THEIR PRODUCTION

摘要

Weather resistant composite articles which have a smooth, bubble-free surface and are sufficiently puncture resistant to pass the DynaTup Instrument Impact Test are produced by an open pour process. These composites include a polyurethane, unreinforced barrier coat and a fiber-reinforced polyurethane layer. These composite articles are particularly useful for the production of doors and panels.
