Glass mat thermoplastics were produced with PET by both melt impregnation and slurry deposition. While both processes resulted in strong, impact resistant composites, the melt impregnated composites, which had longer fibers and higher fiber concentrations than the slurry formed composites, had the greater properties. An in‐mold coating based on reversible crosslinked isocyanate copolymers produced a durable Class “A” finish in laboratory experiments.
