Abstract
Polyurethane composites and methods of preparation are described herein. The polyurethane composites can comprise (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) an inorganic filler, (c) an inorganic fiber, and (d) an organic fiber. Suitable organic fibers can include polyester fibers. The weight ratio of the inorganic fiber to the organic fiber can be from 1:1 to 20:1. Articles comprising the polyurethane composites described herein are also disclosed.
