Elastomeric gasket with multiple skeletons for placement between two parts of an aircraft and a method for making the same

An assembly for use on an aircraft wing having an aircraft skin and a fuel tank, the assembly comprising a metal access door for accessing the fuel tank, a metal retainer ring for engaging the wing and the access door. Fasteners removably couple the access door to the retainer ring. A lip, which may be on the wing surface, is configured to receive a perimeter of the access door when the access door is coupled to the retainer ring. A polyurethane elastomeric gel gasket having a metallic skeleton is configured to lay between the access door and a lip of the metal wing surface. Under compression, the polyurethane will deform and squeeze out the edges and flatten so as to provide metal-to-metal contact between the access door and the lip.

An object of the present invention is to provide a gasket capable of maintaining a surface pressure for a long period of time while securing sealing performance and improving durability and a manufacturing method thereof. A gasket includes a first annular portion which is formed by a metal wire woven fabric and has a seal target hole and a main body portion which is formed by a metal wire woven fabric and is in contact with an outer peripheral edge of the first annular portion, in which a metal wire of the metal wire woven fabric and a metal wire of the metal wire woven fabric are entangled so that the first annular portion and the main body portion are joined to each other and a gap between the metal wires forming the first annular portion is sealed by a resin.

Seal material for analyzer, and flow cell, detector, and analyzer using the same

Provided is a seal material having high rigidity without deformation or breakage, excellent corrosion resistance to fluid, and low solubility when used under high sealing force, and to provide a flow cell, a detector, and an analyzer in which there is no fluid leakage, contamination of the seal material components is prevented, and the replacement frequency is low. Provided are a seal material for an analyzer, including a resin and at least one layer of fiber sheet embedded in the resin, wherein the at least one layer of fiber sheet is embedded between and in substantially parallel to two seal surfaces: a first seal surface, which is one resin surface of the seal material; and a second seal surface, which is the other resin surface substantially parallel to the former one, and a flow cell, a detector, and an analyzer using the seal material.

Gasket and method of producing gasket

A gasket in which a high sealing property can be ensured, and a method of producing such a gasket are provided. A gasket 1 is produced by spirally winding a belt-like composite body 13 having a metal mesh member 11 and expanded graphite 12 enveloped by the metal mesh member, and then compression molding the composite body into a tubular shape. The gasket includes a first sealing portion 21 placed in one axial end portion, and a second sealing portion 22 placed in the other axial end portion. The gasket has a sectional shape in which the composite body that is in a bent state overlaps in a radial direction. The composite body includes a bent portion which is radially bent in an acute angle shape.

Non-planar stick gaskets for receipt between a base and a workpiece

A gasket for placement between a base of an aircraft structure and the underside of a workpiece, such as an aircraft antenna, is disclosed. The gasket has a cured polyurethane elastomeric gel body with a multiplicity of holes therethrough. The body typically has a flat lower surface and upstanding side walls, but the top surface is non-flat. The top surface may have sloped areas or raised tabular areas or a combination. The gel body may also have a skeleton member, such as a flexible metallic screen or other woven member. When the gasket is placed between the aircraft, base and the workpiece, threaded on fasteners, and the fasteners torqued down, the non-flat upper surface will flow such that, at proper torque setting, it fully coats and fully covers the underside of the workpiece and, typically, makes contact with the screen or skeleton member, which also makes contact with the upper surface of the base.

Gasket assembly

A gasket assembly has a middle layer located between an upper layer and a lower layer. The middle layer includes spacer portions that at least partially surround a gap. The gap, the spacer portions and the layers may have insulating and/or conducting portions as needed.
