Abstract
A structural laminate comprises at least one planar facing sheet with a rigid foam attached to one surface of the facing sheet. The rigid foam may be any polymeric material which is capable of being foamed. Distributed substantially evenly throughout the foam is a mat of long glass fibers arranged in layers substantially parallel to the facing sheet. The process for producing this structural laminate comprises the steps of contacting a thin, substantially incompressible yet expansible mat of long glass fibers with a foam-forming mixture, positioning a facing sheet on each face of the mat, and passing the facing sheets having the mat and the foam-forming mixture therebetween through means for metering the amount of foam-forming mixture and causing it to fully penetrate between the fibers of said glass mat.
