The present invention pertains to a fiber-reinforced plastic that has, as at least one of the surface layers in the thickness direction thereof, a layer containing reinforced fibers and a matrix in which a thermosetting resin and a thermoplastic resin are integrated. The reinforced fibers form discontinuous reinforced fiber bundles randomly stacked or discontinuous reinforced fiber bundles arranged in one direction. A portion of the discontinuous reinforced fiber bundles is in contact with both of the thermosetting resin and the thermoplastic resin. The thermoplastic resin is exposed in at least a portion of the surface of the surface layer.

Fiber-reinforced plastic and production method for fiber-reinforced plastic

An imaging table to be supported in a cantilever state on an X-ray imaging apparatus, includes a planar body including an opening portion in a surface to be connected to the apparatus, and a coupling member to be connected to the apparatus. The planar body includes a first member forming a top surface including an X-ray irradiation surface, and a second member forming a bottom surface opposed to the X-ray irradiation surface and a standing wall portion erectly provided on an outer circumference of the bottom surface. The second member is bonded to the first member in the standing wall portion. The first member and the coupling member are bonded to each other. The first member has an aluminum-equivalent X-ray transmission dose of 0.5 mmAL or less at any point in the X-ray irradiation surface.

Imaging table and manufacturing method therefor, mammography apparatus imaging table and manufacturing method therefor, and mammography apparatus

An imaging table for a mammography apparatus is formed by a planar body and is to be supported in a cantilever state on a body of the mammography apparatus. At least an X-ray irradiation surface in the planar body has at least one of the following configurations (1) and (2): (1) the X-ray irradiation surface is formed by a carbon fiber composite material including a unidirectional carbon fiber composite material containing carbon fibers and a matrix resin, the carbon fibers being aligned in one direction; and (2) the X-ray irradiation surface is formed by a skin material and a resin sheet, the skin material including a carbon fiber composite material containing continuous fibers and a matrix resin, the resin sheet being disposed on an inner layer side from the skin material.
