Abstract: A pressurized structure panel for forming a pressurized space pressurized inside includes a panel structure having a panel body to receive the pressure, a rib provided in the panel body, and a hollow part formed by the panel body and the rib, a radiation shielding material provided in the hollow part, and a debris bumper provided outside the panel structure and provided spaced apart from the panel structure by a certain spacing. The radiation shielding material includes a material containing hydrogen atoms in molecules.

Abstract: A bumper is provided on an outer side of a structural body of a spacecraft with a predetermined gap between the bumper and the structural body. The bumper includes: a first layer that is provided on the outer side and that is formed from an impact resistant material; a second layer that is provided on an inner side being on a side of the structural body with respect to the first layer, the second layer having holes; and a third layer that is provided on the inner side with respect to the second layer, the third layer including a resin.

Abstract: Provided is a structural body, formed in a plate-like shape and positioned with respect to an assembly jig including a positioning pin and supporting a first surface of the structural body, including a positioning hole formed through an end portion, a positioning protrusion being inserted into the positioning hole; and a pair of first position detection areas formed on a second surface of the end portion through which the positioning hole is formed. The positioning hole is formed apart from an axis line connecting the pair of first position detection areas.

Abstract: A laminated board includes a difficult-to-cut layer formed of a composite material including fibers and a resin material; and a pair of hard layers laminated on both top and bottom surfaces of the difficult-to-cut layer and formed of a hard material harder than the composite material of the difficult-to-cut layer. Each hard layer is formed of a composite material made of carbon fibers and a resin. The difficult-to-cut layer and the pair of hard layers are integrally molded. Furthermore, the resin included in the difficult-to-cut layer 11 and the resin included in the hard layers 12 are resins of the same type, and an epoxy-based resin is used.

Abstract: A method is for designing a structure in which a composite material including fibers and a resin is arranged as a damping material in a structure body. The method includes selecting a divided arrangement area in which the composite material is to be arranged, the divided arrangement areas being one of divided arrangement areas into which a composite material arrangement area of the structure in which the composite material is arrangeable is divided; selecting a lamination position where the composite material is to be arranged in a thickness direction of the structure; selecting a fiber direction of the fibers; and determining whether a design performance of the structure satisfies performance requirements, the design performance being derived from design parameters including at least the selected divided arrangement area, the selected lamination position, and the selected fiber direction.

Abstract: A suction device is attached to a leading-end section of an articulated arm, attached by suction to a plate-shaped structural member having a curvature at least in a predetermined direction. The suction device includes a support part attached to the leading-end section of the articulated arm; a pair of suction mechanisms having a pair of suction surfaces and disposed apart from each other in an X direction with the attachment position of the support part to the leading-end section interposed between the pair of suction mechanisms; and a pair of first angle adjustment mechanisms capable of adjusting the angle of inclination, in the X direction, of each of the pair of suction surfaces of the pair of the suction mechanisms.

Abstract: The present invention provides a suction hand which is attached to the leading-end section of an articulated arm, attached by suction to a plate-shaped structural member having a curvature at least in a predetermined direction, and provided with: a support part attached to the leading-end section of the articulated arm; a pair of suction mechanisms having a pair of suction surfaces and disposed apart from each other in an X direction with the attachment position of the support part to the leading-end section interposed between the pair of suction mechanisms; and a pair of first angle adjustment mechanisms capable of adjusting the angle of inclination, in the X direction, of each of the pair of suction surfaces of the pair of the suction mechanisms.
