Abstract: A printed sheet for flooring material to be disposed between a backer layer and a top sheet in a flooring material, wherein: the printed sheet for flooring material comprises at least a urethane type resin layer, a printed layer, and a first composite material layer; the printed sheet for flooring material comprises the urethane type resin layer and the first composite material layer in this order from a side of the backer layer in the printed sheet; and the first composite material layer comprises at least an EMAA resin layer and a first polyethylene resin layer in this order from a side of the top sheet in the printed sheet.

Abstract: A manufacturing method for U-bolts comprising the steps of (a) winding a linear, tape or cloth member made of fiber reinforced plastics in which at least a part of the fiber is oriented in three-dimensional directions around a mandrel having a substantially oval or rectangular section (b) making a pipe molded article by hardening the linear, tape or cloth member wound around the mandrel, (c) cutting the hardened pipe molded article into slices transverse to a longitudinal axis of the mandrel, (d) separating the molded article cut into slices into at least two U-shaped portions, and (e) forming screw portions at tip portions of a pair of separated U-shaped portions.

Abstract: A rotary tool for cutting, drilling, grinding, or polishing metallic or non-metallic materials is made of a compact material, which consists of an inorganic fiber reinforced plastic containing 50 to 81 volume % of inorganic long fibers selected from the following group: alumina fibers, boron fibers, silicon carbide fibers, and silicon nitride fibers, the remaining portion of the compact material consisting of a thermosetting resin matrix.

Abstract: A threaded member made of fiber-reinforced plastic (FRP) obtained by the present invention which is characterized by having at least the threaded portion coated with a crosslinked nylon resin. Accordingly, the surface of the threaded portion is smooth, exhibiting adequate elasticity and fitness, and exhibiting excellent screwing ability to enable the smooth meshing of a nut with a bolt without jolting. Moreover, the threaded member is also excellent in weathering resistance and chemical resistance.
