Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing rigid polyurethane foam of a high degree of dispersion with glass fibers dispersed uniformly in a polyurethane molding, and also to provide the polyurethane foam, and an apparatus for producing the rigid polyurethane foam. SOLUTION: In the method for producing the rigid polyurethane foam, a strand mat 2 wound onto a driven roll 1 is delivered downstream by a driving means 3, the delivered strand mat is fibrillated by a fibrillating means 4 while being compressed, and the fibrillated strand mat is coated with the stock solution of the rigid polyurethane foam. Prescribed tension is applied to the strand mat 2 passing through the fibrillating means 4. COPYRIGHT: (C)2008,JPO&INPIT
