Abstract
Foamed molded articles produced by reaction injection molding (RIM) are provided. The molded articles are formed by reaction of a polyisocyanate component with an isocyanate reactive component in a mold using a blowing agent. The molded articles are preferably composites formed in the presence of a fibrous reinforcing material. The foamed articles are characterized by relatively short minimum mold residence times, and can thereby be produced more economically than prior art composites. The foamed articles are further characterized by a reduction in physical defects, such as splits and voids.
