The invention relates to the technical field of composite materials and provides a fiber-reinforced polyurethane foam automobile floor. The fiber-reinforced polyurethane foam automobile floor takes rigid polyurethane foam (1) formed by foaming polyurethane resin as a base body, a first fiber-reinforced body (3) laid in the width direction of the base body is arranged in the rigid polyurethane foam (1), the first fiber-reinforced body (3) is a composite of one or some of glass fiber woven roving, 90-degree unidirection cloth and forging vein cloth, and the glass fiber woven roving, and the 90-degree unidirection cloth and the forging vein cloth are multiple layers distributed in the thickness direction of the base body; continuous glass fiber direct gauze laid in the length direction of the base body is further arranged in the rigid polyurethane foam (1), and the continuous glass fiber direct gauze is located between the adjacent two layers of the glass fiber woven roving, the 90-degree unidirection cloth and the forging vein cloth. The fiber-reinforced polyurethane foam automobile floor has the advantages of being excellent in mechanical property, strong in corrosion resistance, high in strength-intensity ratio, long in life and good in combination property.
