Abstract: A fiber-reinforced pultrusion molded article produced by impregnating a reinforcing fiber bundle assembly containing a plurality of reinforcing fiber bundles bound together with a resin composition containing at least components [A] and [B], followed by curing component [A]: thermosetting resin composition, and component [B]: toughness improving agent, wherein the thermosetting resin composition used as the component [A] is at least one thermoset-ting resin composition selected from the group consisting of epoxy resin composition, vinyl ester resin composition, unsaturated polyester resin composition, and polyurethane resin composition.

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.
