Abstract:
1. A process for producing a beam member formed by a reinforcing fiber base material which has a web portion and at least a pair of flange portions extending to both sides via at least a branching point from the web portion, at a cross-sectional surface orthogonal to a longitudinal direction of the beam member, and by a shaped filler which fills a gap having a wedge shape formed at the branching point, and wherein a thickness of the reinforcing fiber base material changes in a longitudinal direction of the beam member and also a curvature radius of the reinforcing fiber base material at the branching point changes in the longitudinal direction of the beam member along a change of the thickness, and wherein the shaped filler is produced by at least the following production processes (A) to (C): (A) a filler supply process for supplying a filler member configured by reinforcing fibers, wherein a reinforcing fiber sheet of which a quantity of reinforcing fibers changes in a longitudinal direction is supplied as the filler member; (B) a preshaping process for providing a preshaped filler having at least a wedge projection portion, by pressurizing the filler member by a preshaping mold, wherein the preshaped filler of which a cross-sectional shape changes in a longitudinal direction is formed by using a preshaping mold made of at least two mutually opposing molds, and by changing a gap between the molds by changing a relative position between the molds in accordance with a passing of a filler member between the molds, and further, the reinforcing fiber base material and the preshaped filler are intermittently carried by synchronizing the both in a longitudinal direction, and the process (C) is performed immediately after the preshaped filler passes the preshaping mold; and (C) a filler deforming process for providing a shaped filler by deforming the preshaped filler, by filling the preshaped filler into the gap and by pressurizing the preshaped filler such that a tip of the wedge projection portion is directed to a tip of the gap having a wedge shape.
