    摘要： A block is configured such that, when a composite material having a curved part in a cross-sectional shape cut by a plane orthogonal to an X-axis is deformed into a shape corresponding to a mold through pressure application while being kept in the mold, the block is brought into contact with the curved part of the composite material. The block includes: a first contact part which extends along the X-axis direction so as to be in contact with the curved part of the composite material; and a second contact part which is partially disposed along the X-axis direction, is in contact with the curved part of the composite material, and is of higher rigidity than the first contact part.

    摘要： The present invention discloses a method and apparatus for molding a fibrous molded article. An aqueous slurry that contains an amount of water and a plurality of fibers is added to the molding apparatus. First and second molding screens are positioned on a first pressing unit and a second pressing unit, respectively, and include a plurality of openings. The first and second molding screens can include secondary relief features. A pressing chamber sleeve slidably engages with the first pressing unit and the second pressing unit to ensure proper alignment during molding operation. The first and second molding screens at least partially form a void that is intended to receive an amount of the aqueous slurry. The apparatus includes a heat and pressure source that removes at least some of the water from the aqueous slurry and bonds the fibers to one another resulting in the fibrous molded article.

    摘要： A resin shaping mold includes an upper mold, a lower mold arranged to be opposed to the upper mold, a sliding mechanism configured to be slidable on a surface of the lower mold and having a pressing surface including a surface directed in a different direction from a direction of pressing on a resin by the upper mold and the lower mold, and a rubber member formed to cover at least the pressing surface of the sliding mechanism and a gap between the pressing surface and the lower mold.

    摘要： A vacuum bag having an expandable pleat is provided. The vacuum bag includes a first surface region, a second surface region, and a third surface region between the first and second surface regions. The third surface region can be folded to bring the first surface region into proximity of the second surface region. The vacuum bag also includes a strip having a first attaching region at a first end of the strip, a second attaching region at a second end of the strip opposite the first end, and a central region between the first and second attaching regions. The first attaching region is fixed to the first surface region, and the second attaching region is fixed to the second surface region such that when the central region of the strip is in a non-expanded state, the first surface region is contiguous to the second surface region.
