Flexible pipe and coupling therefor

Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

A system of connected elements for a motor vehicle includes: a first element which has at least one depression on a surface; a second element which is arranged on the first element in such a manner that a surface of the second element and the depression of the first element form a cavity; a filling opening which forms an access to the cavity; and an adhesive which at least partially fills the cavity and thereby adhesively bonds the first element to the second element.

SYSTEMS AND METHODS FOR JOINING NODES AND OTHER STRUCTURES

An additively manufactured node is disclosed. A node is an additively manufactured (AM) structure that includes a feature, e.g., a socket, a channel, etc., for accepting another structure, e.g., a tube, a panel, etc. The node can include a node surface of a receptacle extending into the node. The receptacle can receive a structure, and a seal interface on the node surface can seat a seal member between the node surface and the structure to create an adhesive region between the node and the structure, the adhesive region being bounded by the node surface, the structure, and the seal member. The node can also include two channels connecting an exterior surface of the node to the adhesive region. In this way, adhesive can be injected into the adhesive region between the node and the structure, and the adhesive can be contained by the seal member.

System and method for repairing a composite structure

A method of repairing a composite structure includes providing an assembled composite structure comprising a substantially rigid outer component, wherein the composite structure comprises a void space at least partially bounded by the outer component. The method further includes forming an injection hole through the outer component to provide a path between the void space and space external to the composite structure. The method further includes injecting foam into the void space through the injection hole while the foam is in a substantially unexpanded state and expanding the foam within the void space.

Device for attaching mouthpiece to innerliner of aircraft water tank

A device for attaching a mouthpiece to an innerliner of an aircraft water tank is provided. A cylinder portion of an innerliner is thermally deformed to conform to an inner circumferential portion of a cylinder-like portion, and an inner circumferential portion of a dome portion of the innerliner is attached to a skirt portion by an adhesive. A lower mold includes two sections inserted inside the innerliner from the inner side of a mouthpiece in a folded state. The two sections are opened inside the innerliner and a holding member holds the two sections in an open state. The lower mold can be disposed in the innerliner sealed from the inner side of the mouthpiece, and abutment of an outer abutting surface of an upper mold against a first annular surface and abutment of an inner abutting surface of the lower mold against a second annular surface can be performed.

A method for repairing window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.

SYSTEM AND METHOD FOR FORMING A SEAL BETWEEN STRUCTURAL COMPONENTS
20210316839 · 2021-10-14 ·

A method for forming a seal between structural components includes placing a retainer flap on a first side of a first structural component over a first channel within the first structural component and over a second channel within the first structural component such that the retainer flap, the first side of the first structural component, and a second structural component form a cavity. The first channel extends between the first side of the first structural component and a second side of the first structural component that is opposite the first side. The second channel extends between the first side of the first structural component and the second side of the first structural component. The method also includes evacuating the cavity through the first channel, thereby forcing the retainer flap against the second structural component and forcing a sealant to flow through the second channel into the cavity.

Method of applying an high velocity oxygen fuel (HVOF)-resistant masking tape to the surface of a workpiece (112) such that multiple lengths of tape (116, 118) are abutted to one another to form butt joints (132), the butt joint (132) is then covered with additional lengths of tape (120).

Apparatus, method and system to temporarily hold a workpiece during manufacturing using adhesive attachment

A method and system temporarily holds a workpiece, most suitably an aero engine turbine blade element during manufacture. The workholding system includes a support body with a contoured body surface, complementary to a workpiece surface, formed of a transparent material to define a bonding zone. The support body is supported by a base to form a workpiece shuttle, and a bond station receives the workpiece shuttle. Complementary zero-point locating elements on the shuttle and station assure accurate positioning. The bond station further has workpiece locating elements configured to accurately position the workpiece on the shuttle in a predetermined position relative to the zero-point locating elements of the shuttle, thereby compensating for shuttle-to-shuttle variance. An adhesive, such as a UV curable adhesive, is applied to the bonding zone and cured by UV through the transparent material, thereby fixing the workpiece in the predetermined position.
