The laminate (1) includes a divided layer (12) which is a layer having three or more regions by being divided into three or more in planar view in a subject direction. A thermal expansion coefficient in the subject direction of a material that constitutes at least one region of the regions of the divided layer (12) differs from a thermal expansion coefficient in the subject direction of a material that constitutes at least one region of other regions of the divided layer (12).

A cover (10) for an air conditioning device for a railway vehicle is a cover for an air conditioning device for a vehicle, which covers an air-conditioner main body. The cover (10) includes a core (11) made of a foamed material having heat insulating property, and a surface member (12) made of a fiber reinforced plastic, which covers entire surfaces of the core (11). The core (11) is deformed into a curved shape by elastic deformation.

A solar array wing (100) includes an extension mast (120) to be extended from a wound state, and a support member (130), around which the extension mast is wound, to support the extension mast after the extension mast is extended. The support member is made of a fiber reinforced composite material. A coefficient of linear expansion of the fiber reinforced composite material, a unit of which is for each degree Celsius, in a direction that is orthogonal to an extension direction of the extension mast, is higher than or equal to -1×10 -6 and lower than or equal to 1×10 -6 .

A honeycomb sandwich structure comprises a main body portion having a first skin material (1), a second skin material (2), and a honeycomb core (5) sandwiched between the first skin material (1) and the second skin material (2), and a thermoelectric conversion module (3) that generates power using a temperature difference between a high temperature side module front surface (3a) and a low temperature side module rear surface (3b). The thermoelectric conversion module (3) is embedded in a main body portion such that at least one of the module front surface (3a) and the module rear surface (3b) is in a state being exposed from the main body portion, and as a result, a temperature difference is generated between the module front surface and the module rear surface.

An extensible boom (120) is extended in an extension direction from a state of being rolled in a cylindrical form, the extension direction being one of short directions of the cylindrical form. Protruding portions (125) and recessed portions (126) are alternately formed at each of one end and another end in a long direction of the cylindrical form. The protruding portions (125) at the one end are located opposite the recessed portions (126) at the other end. The recessed portions (126) at the one end are located opposite the protruding portions (125) at the other end. When the extensible boom (120) is extended, along the extension direction, from the state of being rolled in the cylindrical form, the protruding portions (125) at the one end engage with the recessed portions (126) at the other end, and the recessed portions (126) at the one end engage with the protruding portions (125) at the other end, such that a cylindrical shape is formed along the extension direction.

A gauge carrier (200) holds an optical fiber (100) which has a gauge portion (101) of a predefined length used for detection of strain provided in one axial part thereof. A center region (201) has a predefined stiffness and holds the gauge portion (100), where the length in the longitudinal direction of the gauge carrier (200) is equal to or greater than the length of the gauge portion (100). Two split regions (202) each have a stiffness different from the stiffness of the center portion (201), a total length of lengths of the respective split regions (202) in the longitudinal direction of the gauge carrier (200) is greater than the length of the center region (201) in the longitudinal direction of the gauge carrier (200), one of the split regions (202) is positioned in front of the gauge carrier (200) and holds a part of light (100) that is in front of the gauge portion (101), and the other is positioned in back of the gauge carrier (200) and holds a part of the optical fiber (100) that is in the back of the gauge portion (101).

A honeycomb sandwich structure in which moisture absorption deformation can be sufficiently suppressed and a method for manufacturing the same are provided. The honeycomb sandwich structure (1) includes: a honeycomb core (3) having a recess (6b) at a mesh of a carbon fiber fabric; a pair of face plates; a resin layer (8b) which fills a part of the recesses (6b); and a water-impermeable film (7b) which covers an exposed area including surfaces of the resin layer (8b) and the honeycomb core (3), wherein the recess (6b) includes an unfilled part (61b), the unfilled part being a part of the recess that is closer to the recess's opening, the unfilled part being not filled with the resin layer (8b).
摘要:
This invention is concerning a honeycomb core configured to include carbon fiber having four or more different fiber directions, wherein, when a ribbon direction is set as an X axis direction, a cell width direction is set as a Y axis direction, and a direction that is orthogonal to the ribbon direction and the cell width direction is set as a Z axis direction, and a condition in which angles formed by the X axis direction and the respective fiber directions of the carbon fiber are set at -45°, 0°, 45°, and 90° is set as a reference condition, the respective fiber directions are rotated from the reference condition by a fixed rotation angle so that none of the fiber directions are parallel to the X axis direction.
