  • Patent number: 11131565
    Abstract: A method of manufacturing an annular insert molded article that suppresses contamination of a metal mold and generation of foreign matter without increase in material costs for an adhesive or contamination of a transfer jig, and has a high adhesion strength so that, when the annular insert molded article is attached to a rotating body, the adhesive does not peel off from the insert or remain as foreign matter in the rotating body. An annular insert molded article 1 is manufactured by injection molding in a state where a thermoset resin adhesive A is applied to a joining surface of an annular insert 2 attachable to a rotating body to an annular plastic 3 and then the annular insert 2 and the annular plastic 3 are placed in a metal mold.

  • Patent number: 11105731
    Abstract: A freestanding coating membrane is fabricated and is tested for ionic transport. An adhesive liner is situated on a flat surface, paint is poured on the liner, a leveling blade is used to impart a uniform thickness to the uncured paint, the paint when completely cured is peeled from the liner, and the thickness of the resultant freestanding membrane is measured. Saline water is placed in an open-ended reservoir in communication with an assembly holding the freestanding membrane and containing deionized water. A pump causes water to circulate through the assembly via a conduit, which is connected at both ends to the assembly. The electrical conductivity of the circulating water is monitored for an appropriate duration for indication of salt concentration. The conductivity is initially low because the circulating water is originally deionized, and gradually increases commensurately with the amount of salt (e.g., chloride) ions passing through the membrane.

  • Publication number: 20150079340
    Abstract: Large area graphene (LAG) sheets can be embedded in a polymer-based material as a mechanical reinforcement or to otherwise enhance the properties of the polymer-based material. The LAG sheets can be nanoperforated and/or functionalized to enhance interaction between the graphene and the polymer. Reactive functional groups can facilitate formation of covalent bonds between the graphene and the polymer so that the LAG sheets become an integral part of the cross-linked structure in curable polymer-based materials. Nanoperforations in the LAG sheets provide useful sites for the functional groups and can allow cross-links to form through the nanoperforations.

    Abstract: The present disclosure pertains to a window panel for a body structure of a vehicle, especially an airframe of an aircraft or spacecraft, including a first skin which extends over a first side of the panel to form an outer skin of the vehicle body structure; a second skin which extends over a second side of the panel to form an inner skin of the vehicle body structure; and a core, especially a foam core, located between and covered by the first and second skins in a sandwich structure. The window panel includes at least one window aperture formed through the first layer, the core, and the second layer. The core may be confined to or extends over a limited extent, region or part of the panel. Thus, the first skin and/or the second skin may extend over or cover a greater area of the panel than the core.

  • Patent number: 8951375
    Abstract: A method and apparatus for fabricating a composite part, such as a fuselage or internal stiffener, with a shape memory polymer (SMP) apparatus usable as both a rigid lay-up tool and a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. Next, composite material may be applied onto the SMP apparatus and then placed into a rigid external tool and heated to composite cure temperatures at which the SMP apparatus is malleable. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external tool. When the composite material is cured, the SMP apparatus may be urged away from the cured composite material and removed from within the composite part.
