摘要：
Fiber-reinforced polyurethane structures are made with a polyol composition that contains a particulate filler such as calcium carbonate, in addition to the fibers. The polyol composition and the polyisocyanate composition are selected such that the polymer formed in their reaction has a calculated molecular weight between crosslinks (Mc) of from 300 to 420. The polyisocyanate component contains a urethane-modified MDI and/or a urethane-modified polymeric MDI.
