Abstract: The coating quality prediction device includes: a learned model that has learned a relationship between characteristics of a paint, conditions at a time of applying the paint, and a smoothness of a surface of a coating film obtained by applying the paint under the conditions; and a calculation unit that uses the learned model to calculate the smoothness of the surface of the coating film from the characteristics of the paint and the conditions at the time of applying the paint.

Abstract: 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.

Abstract: A method for molding a fiber-reinforced plastic member involves disposing a reinforced-fiber base material 2 inside a molding space S, which is created between a mold 1 and a bag film 6, and then depressurizing the inside of the molding space S and curing a resin composition R contained in the reinforced-fiber base material 2, wherein a flat pressure plate 5 made of spring steel is disposed between the reinforced-fiber base material 2 and the bag film 6. The pressure plate 5 elastically deforms along the shape of the reinforced-fiber base material 2 while the inside of the molding space S is being depressurized, and returns to its original flat shape when depressurization is stopped and the bag film 6 is removed after curing of the resin composition R.

Abstract: 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.

Abstract: A device 100 for molding a fiber-reinforced plastic structure is a device for manufacturing a fiber-reinforced plastic structure 200 integrating a stringer 2, 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 1, which is a fiber-reinforced plastic member. The skin 1 is provided with a positioning plate 3, which is disposed along the skin 1 and engages with a bottom surface 201 of an end part 21 of a mandrel 20 for molding the stringer 2. The positioning plate 3 positions the stringer 2 relative to the skin 1, at least in the direction intersecting the longitudinal direction D.

Abstract: In the manufacturing method of the present invention, as preparation for providing a mold 30 with protrusions 31 and 32 to be printed on an FRP material of a skin 1 in co-bold molding, which requires resetting of the skin 1 to the mold 30, a long protrusion 32A and a short protrusion 32B are interchangeable as one protrusion 32. The long protrusion 32A is printed to form a second recessed part 12 in the skin 1, and before the skin 1 is reset, the long protrusion 32A is replaced with the short protrusion 32B. In this way, as the short protrusion 32B is housed in the second recessed part 12 formed during elongation of the mold 30, the skin 1 can be reset in the state of being positioned relative to the mold 30 by the first protrusion 31 and the short protrusion 32B.

Abstract: The molding method of the present invention configures: a mandrel 2 being a mold for molding the material of a fiber-reinforced plastic 1 and having multiple pieces 21 to 24 adjacent to one another in a longitudinal direction D; and an angle material 3 formed of a material having a linear expansion coefficient approximate to the linear expansion coefficient of the fiber-reinforced plastic, and aligning the pieces 21 to 24 along the longitudinal direction D. The method includes: a mandrel disposing step S2 of disposing the pieces 21 to 24 with gaps G1 to G3 between one another; an angle material disposing step S3 of disposing the angle material 3 on the pieces 21 to 24; and a heating to cure and molding step S5 of molding the fiber-reinforced plastic by heating the material of the fiber-reinforced plastic while aligning the pieces 21 to 24 by the angle material 3.
