Abstract
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.
