  • Publication number: 20230021569
    Abstract: A fiber reinforced resin hollow molded body 30 in which a resin-integrated fiber sheet is used. The resin-integrated fiber sheet includes unidirectional continuous fibers that are spread fibers of a continuous fiber group and arrayed unidirectionally in parallel, and thermoplastic resin that is present at least on a surface of the unidirectional continuous fibers. In the hollow molded body, in a state where the resin-integrated fiber sheet or a plurality of the resin-integrated fiber sheets 30 are stacked, the resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are wound to produce a wound body having an overlapping portion. The thermoplastic resin is impregnated in the unidirectional continuous fibers. The resin-integrated fiber sheet or the plurality of resin-integrated fiber sheets are consolidated.

  • Publication number: 20220388275
    Abstract: A resin-integrated fiber sheet 1 for vacuum forming for producing a fiber reinforced resin molded body through vacuum forming includes: unidirectional continuous fibers 2 that are spread fibers of a continuous fiber group and arrayed in parallel in one direction; bridging fibers 3 lying in directions crossing the unidirectional continuous fibers 2; and thermoplastic resin 4 present on part of the surface of the unidirectional continuous fibers 2 to unify the unidirectional continuous fibers 2 and the bridging fibers 3. A fiber reinforced resin molded body of the present invention is a vacuum formed body in which two or more of the resin-integrated fiber sheets 1 are stacked. A method for producing the molded body of the present invention includes subjecting the resin-integrated fiber sheets 1 to vacuum forming from a lower mold with a vacuum line and pressurizing the sheets with compressed air from an upper mold.

  • Publication number: 20220205157
    Abstract: A resin-integrated carbon fiber sheet 1, including: a carbon fiber sheet 2 in which a carbon fiber filament group is spread and arrayed in parallel in one direction; resin 4 that is present on part of a surface of the carbon fiber sheet; and bridging fibers 3. One or more of the bridging fibers 3 is present on average on a surface of the carbon fiber sheet 2 in a direction across the carbon fiber sheet per 10 mm2 of the sheet 2, and the resin 4 on the surface adhesively fixes the bridging fibers 3 to the carbon fiber sheet 2. Thus, the present invention provides a resin-integrated carbon fiber sheet that is strong in the width direction of the carbon fiber sheet, high in cleavage resistance and excellent in handleability, and a production method of the same.

  • Publication number: 20070164502
    Abstract: An image forming apparatus includes an apparatus main body that carries out an image forming processing with respect to a sheet. A sheet supplying unit is mounted detachably into the apparatus main body and adapted to supply a sheet from a stack of sheets stored therein toward an inside of the apparatus main body. The sheet supplying unit includes a position keeper for keeping the sheet stack in a determined position by contacting sides of the stack. The keeping position is changeable in accordance with the size of a sheet. A lock mechanism locks the position keeper in a keeping position. The locking mechanism releases the locking of the position keeper when the sheet supplying unit is detached from the apparatus main body and placed on a surface. However, the locking mechanism locks the position keeper when the sheet supplying unit is lifted from the surface.
