  • Patent number: 10913553
    Abstract: An integrated heat shield which encloses a frame structure comprises a leading edge component, a left side component, a right side component, an optionally top component, an optional bottom component and an optional trailing edge subassembly, wherein the leading edge component and the left and right side components are directly, integrally co-cured on the frame structure while in a B-stage. The leading edge component and the left and right side components are shingle laminated to form ply angles to air flow. The leading edge component and the side components are scarf-jointed or step-jointed. The side components and trailing edge subassembly are also scarf jointed or step-jointed. The co-curing as well as the scarf or step joints makes the heat shield an integrated assembly. A method of manufacturing the integrated heat shield is further introduced.

  • Publication number: 20160178340
    Abstract: A measurement and operation auxiliary device, for supporting a length measurement tool disposed on an object under test, especially when measuring dimensions of a large object under test with a large length measurement tool, includes a fastening element, a connection shaft, and a support unit. The fastening element is unfastenably coupled to the object under test. The connection shaft is disposed on the fastening element. The support unit has a receiving chamber and a through hole. The connection shaft is penetratingly disposed in the through hole to allow the support unit to be rotatably coupled to the fastening element. The receiving chamber receives the length measurement tool. With the measurement and operation auxiliary device, the bulky length measurement tool can be fixed to a location suitable for measuring the dimensions of the large object under test without another co-worker and in a convenient, labor-saving manner.

  • Patent number: 8647457
    Abstract: Disclosed is a method for making a rubber liner of a composite pressure vessel. At first, rubber is located in a mold. The rubber and the mold are located in a vacuum bag, heated and pressed so that the rubber is vulcanized and molded into a semi-product of the rubber liner. Sand is filled in the semi-product. The sand is tamped and heated so that it is hardened and molded. A reinforcement element in the form of a wire or tape is wound around the semi-product. Two semi-products are brought into contact with each other. An un-vulcanized rubber band is provided around and attached to the semi-products. The rubber liners and the reinforcement elements are heated and vulcanized with composite resin. Finally, the water soluble sand mold is dissolved and removed so that the final product of the rubber liner is made, and so is the composite pressure vessel.

  • Patent number: 7799160
    Abstract: The present invention relates to a method for manufacturing a composite container with different opening sizes, which is accomplished by winding with fibers impregnated with resin. First, fibers impregnated with resin are wound on a first substrate for winding a first container, wherein first openings are positioned at both ends of the first container. Then, cut the first container into two shells with a first opening each, and slip one of the shells on a second substrate. Next, fibers impregnated with resin is used for winding the second substrate and the shell such that the fibers impregnated with resin wound on the second substrate and the shell are combined to form a second container, where both ends of the second container are the first opening and a second opening with different opening sizes. Thereby, filament winding can be applied for manufacturing containers with different opening sizes on both ends, and the technique of manufacturing and performance of containers are enhanced.
