Abstract
Polyurethane composites comprising non-silane treated glass fibers and methods of manufacturing are described herein. The polyurethane composites can include (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; (b) a filler; and (c) non-silane treated glass fibers. In some instances, none of the glass fibers in the polyurethane composites are silane treated. The polyurethane composites comprising the non-silane treated glass fibers can have a flexural strength that is greater than the flexural strength of an identical composition wherein the non-silane treated glass fibers are replaced with silane-treated glass fibers. Articles comprising the polyurethane composites are also disclosed herein.
