摘要： A method of molding composite materials including shaping a laminate having fiber sheets laminated over one another, by bending the laminate in an X-direction and a Y-direction, in a three-dimensional orthogonal coordinate system. The method further includes mounting the laminate that has been shaped, onto a mold material deformed in a Z-direction, impregnating a resin material into the laminate while adjusting an amount of the resin material filled in, and molding the composite materials that have cured such that the composite materials are shaped to have a first inclined surface inclined at a first inclination angle with respect to a reference plane in the Z-direction. The mold material has a first inclination molding surface that molds the first inclined surface, and a second inclination molding surface that molds a surface of the composite materials into a second inclined surface having a second inclination angle smaller than the first inclination angle.

摘要： A method for molding a composite material obtained by laying up a fiber-reinforced base material includes: disposing a lay-up in which the fiber-reinforced base material is laid up, on a molding surface of a molding jig; covering the lay-up with a film to hermetically seal the lay-up; supplying resin toward the lay-up from a resin supplying unit; sucking atmosphere in the film from a degassing waterproof unit while blocking the resin in the film from passing to impregnate the lay-up with the resin; and discharging the resin in the film from a resin discharging unit after the lay-up is impregnated with the resin. The resin supplying unit is provided on the film side. The degassing waterproof unit is provided on the molding surface side and along one direction in a plane perpendicular to a laying-up direction of the lay-up. The resin discharging unit is provided at the film side.

摘要： A manufacturing device manufactures a composite material structure by impregnating resin into a preform formed in a predetermined shape. The manufacturing device includes: a caul plate defining a space inside and covering the preform in the space; a supply part that supplies resin to the preform; a discharge part that discharges a gas from the space through a discharge hole in the caul plate; and a pressure intensifier that is provided in the space and between the caul plate and the preform and pressurizes the preform by a gas being discharged through the discharge part. The pressure intensifier has a web part facing surface facing the preform and a caul plate facing surface facing the caul plate, and through holes between the web part facing surface and the caul plate facing surface are in the pressure intensifier.

摘要： A method for molding a composite material in which a curved corner is formed between two planes by using a molding jig includes: shaping a laminated body in such a manner that a thickness of the laminated body is decreased from an outer side toward an inner side of the corner, by using the molding jig in which the angle formed by the two planes is a first bending angle, the laminated body including fiber sheets laminated so as to have the corner curved at the first bending angle; and shaping the laminated body in such a manner that the thickness is decreased from the outer side toward the inner side by curving the corner so as to form a second bending angle, by using the molding jig in which the angle formed by the two planes is the second bending angle smaller than the first bending angle.

摘要： A method for manufacturing a composite material includes placing a netlike sheet material, through which a resin composition permeates, on reinforcing fiber substrates disposed on a forming die. The method includes covering the reinforcing fiber substrates disposed on the forming die and the bag surface-smoothing sheet with a bag film to form a sealed forming space between the bag film and the forming die. The method includes infusing a resin composition into the forming space to impregnate the reinforcing fiber substrates. The method includes curing the resin composition impregnated in the reinforcing fiber substrates. Warp yarns and weft yarns are disposed in a lattice pattern and, after placing the bag surface-smoothing sheet on the reinforcing fiber substrates so that the warp yarns and the weft yarns form acute angles with respect to corners of the reinforcing fiber substrates, the bag surface-smoothing sheet projecting from the reinforcing fiber substrates is bent.

摘要： A molding jig for molding a laminate, which includes reinforced fiber sheets laminated on each other, extends in the length direction, and has a cross-sectional shape having a curved portion in a cross section obtained by cutting the laminate on a plane orthogonal to the length direction, into a three-dimensional shape having a bent portion in the length direction. The molding jig includes a female die for forming the bent portion, a male die for engaging with the female die with the laminate therebetween for forming the bent portion, and a stretchable supporting member between the female die and the laminate. The laminate comes in contact with the male die on both length-direction sides of the molded bent portion, and the supporting member is over a region including the female-side molding surface.
