A workpiece support system includes: a plurality of rods that are extendable and retractable in an axial direction; a holder rotatably placed in an upper end portion of each of the rods, to hold a workpiece; a first lock part that keeps an extended/retracted position of the rod in the axial direction; and a position adjustment device including a hand portion configured to hold the rod or the holder, to perform position control of the hand portion. The position adjustment device moves the hand portion, to extend and retract the rod, based on shape data of the workpiece that is recorded in advance, in a state where the rod or the holder is held by the hand portion, and the first lock part keeps the extended/retracted position of the rod extended and retracted by the position adjustment device.

Workpiece support system and workpiece support method

A method for molding a fiber-reinforced plastic member involves disposing a reinforced-fiber base materialinside a molding space S, which is created between a moldand a bag film, and then depressurizing the inside of the molding space S and curing a resin composition R contained in the reinforced-fiber base material, wherein a flat pressure platemade of spring steel is disposed between the reinforced-fiber base materialand the bag film. The pressure plateelastically deforms along the shape of the reinforced-fiber base materialwhile the inside of the molding space S is being depressurized, and returns to its original flat shape when depressurization is stopped and the bag filmis removed after curing of the resin composition R.

Method and device for molding fiber-reinforced plastic member

This molding die used for molding a composite material comprises: a molding member having a molding surface; a support frame that is provided on the lower side of the molding member, and that supports the molding member; and a height adjustment mechanism that is provided between the molding member and the support frame, and that is capable of adjusting the height of the molding member with respect to the support frame. The thermal expansion coefficient of the molding member is less than or equal to the thermal expansion coefficient of the support frame. Three wheels that travel on a floor surface while supporting the support frame at three points are provided on the lower side of the support frame.

Molding die and method for molding composite material

A devicefor molding a fiber-reinforced plastic structure is a device for manufacturing a fiber-reinforced plastic structureintegrating a stringer, which is a fiber-reinforced plastic member having a longer dimension in a longitudinal direction D than in a direction perpendicular to the longitudinal direction D, with a skin, which is a fiber-reinforced plastic member. The skinis provided with a positioning plate, which is disposed along the skinand engages with a bottom surfaceof an end partof a mandrelfor molding the stringer. The positioning platepositions the stringerrelative to the skin, at least in the direction intersecting the longitudinal direction D.

Device and method for manufacturing fiber-reinforced plastic structure

In the manufacturing method of the present invention, as preparation for providing a moldwith protrusionsandto be printed on an FRP material of a skinin co-bold molding, which requires resetting of the skinto the mold, a long protrusionA and a short protrusionB are interchangeable as one protrusion. The long protrusionA is printed to form a second recessed partin the skin, and before the skinis reset, the long protrusionA is replaced with the short protrusionB. In this way, as the short protrusionB is housed in the second recessed partformed during elongation of the mold, the skincan be reset in the state of being positioned relative to the moldby the first protrusionand the short protrusionB.

Method and mold for manufacturing fiber-reinforced plastic structure

The molding method of the present invention configures: a mandrelbeing a mold for molding the material of a fiber-reinforced plasticand having multiple piecestoadjacent to one another in a longitudinal direction D; and an angle materialformed of a material having a linear expansion coefficient approximate to the linear expansion coefficient of the fiber-reinforced plastic, and aligning the piecestoalong the longitudinal direction D. The method includes: a mandrel disposing step Sof disposing the piecestowith gaps Gto Gbetween one another; an angle material disposing step Sof disposing the angle materialon the piecesto; and a heating to cure and molding step Sof molding the fiber-reinforced plastic by heating the material of the fiber-reinforced plastic while aligning the piecestoby the angle material
