Abstract: A method of producing a fiber-reinforced molded article includes abrading a reinforcing fiber bundle to which a thermosetting resin composition is applied in a resin impregnation bath through a plurality of squeezers while applying tension to the bundle to impregnate the reinforcing fiber bundle with the thermosetting resin composition to provide a resin-impregnated fiber bundle and wring out excess thermosetting resin composition; and heat-curing the thermosetting resin composition while passing the fiber bundle through a mold to perform pultrusion molding into a predetermined shape, wherein a mold inlet cross-sectional shape of an insertion hole provided to the mold, the insertion hole being configured to allow insertion of the resin-impregnated fiber bundle, is similar to a cross-sectional shape of the fiber-reinforced molded article, the cross-sectional shapes being sections cut in a direction normal to a pultrusion direction; the squeezers each include a fiber inlet part and a fiber squeezing part.

Abstract: An inorganic fire-proof coating material can form a coat film to be transformed into a foamed layer demonstrating quite superior heat insulation ability by uniform foaming as subject to heat, such as that upon fire to prevent softening of the steel material coated by the coat film for a long period to be sufficiently practically applicable as a fire-proofing coat for steel frame structure or the like, and an inorganic fire-proof structure formed by coating the fire-proof coating material. The fire-proof coating material is consisted of an aqueous paste containing water soluble alkaline silicate in a content greater than or equal to 30 Wt % in components excluding water, holmite series mineral powder, and SiO2 supplying components other than water soluble alkaline silicate and holmite series mineral.
