  • Patent number: 11285641
    Abstract: Described are methods and systems for manufacturing curved composite stringers. Such composite stringers may have in-plane and/or out-of-plane bends, which are formed while shaping composite charges. Specifically, a composite charge is shaped using a pallet, comprising a plurality of independent pallet portions, rotatably coupled to each other. A hat portion is formed when a part of this charge is conformed to a cavity in the pallet. The pallet portions are rotated relative to each other while forming the hat portion and/or when the hat portion already conforms to the cavity. In some examples, the die is bent together with the charge, when the pallet portions are rotated. This rotation produces one or more of in-plane and/or out-of-plane bends. In some examples, flange portions of the composite charge are positioned in a temporary orientation, e.g., to enable bending of the charge and reduce wrinkles.

  • Patent number: 11267549
    Abstract: A method for manufacturing a resin sheet includes a coating step; a heating step; and a pressurizing step. In the coating step, linear metal nanomaterial is coated on a surface of a resin film having thermal plasticity. In the heating step, the resin film having the linear metal nanomaterial coated on the surface thereof is heated and softened. In the pressurizing step, the resin film having the linear metal nanomaterial coated on the surface thereof is pressurized to press the linear metal nanomaterial along a direction orthogonal to the surface on which the linear metal nanomaterial is coated. Thus, the coated linear metal nanomaterial penetrates the resin film to obtain the resin sheet containing the linear metal nanomaterial.

  • Patent number: 11241873
    Abstract: For forming a sound absorption/insulation honeycomb panel by stacking an air-permeable material, a honeycomb material filled with a sound absorption material and a reflector, and adhesively joining these materials, it is hard to join the honeycomb material and the air-permeable material adhesively due to a thin wall surface of the honeycomb material and a resultant line to surface adhesive joint therebetween, causing a problem of low adhesive strength. By using a water absorption honeycomb material, an adhesive joint is formed with an adhesive joint area increased by dipping an end of a wall surface of a cell forming the water absorption honeycomb material into a water-soluble adhesive, making the end flexible over a fixed period of time, and then pressing the end strongly against an air-permeable material as a counterpart of the adhesive joint to deform a tip into an inverted T-shape.
