Abstract
A high density structural reaction injection molded (SRIM) composite having a fabric comprised of nonwoven spunbonded fibers made of a polyester core sheathed in a polyamide skin, is embedded in a polyurethane matrix, providing a part having a blister free surface upon baking in a paint oven. A baked part having a near Class A or Class A surface finish can be attained by adding a show surface veil made of a soft nonwoven polyester fiber mat to the polyurethane matrix over the nonwoven spun bonded fabric. These parts have structural applications which require high strength and good surface finishes, such as in automotive exterior panels.
