Claim Text:
1. A fiber-reinforced polyurethane composite plate having a thickness of at least 12 mm, wherein the fiber-reinforced polyurethane composite contains at least 20% by weight of reinforcing fibers embedded in a polyurethane polymer matrix which is a reaction product of a polyurethane-forming formulation that omits water and other blowing agents, which polyurethane polymer matrix has a calculated molecular weight between crosslinks of from 430 to 2500, wherein the fibers have lengths of from 12 to 150 mm and are randomly oriented in the polyurethane polymer matrix and the polyurethane polymer matrix is a reaction product of an isocyanate composition that includes polymeric MDI and has an isocyanate equivalent weight of from 125 to 168 and an average isocyanate functionality of from 2.2 to 4.0, and a polyol composition that contains isocyanate-reactive compounds having an average equivalent weight per isocyanate-reactive group of from 125 to 300 and an average of from 2.0 to 3.5 isocyanate-reactive groups per molecule.
