Abstract:

Applicant provides a number of embodiments of a sealant, the sealant comprising a polyurethane gel which, in some embodiments, has a thickness of 12 mil or less (uncompressed). Uses of the sealant are shown, including uses between aircraft parts under compression. Sometimes the sealant may have a very thin skeleton. Sometimes the sealant is in the form of a die cut gasket, a tape or a tacky gel sprayable. Methods for making the sealant are also disclosed. The sealants may be used pre-cured or may be sprayed on to the aircraft parts and form in place.

Abstract:

A thin, cured gel gasket is disclosed, including methods of making the thin gel gasket and the use of the thin gel gasket in an aircraft joint. In one embodiment, the thin gel gasket has no skeleton or other structure and is comprised of only a cured polyurethane gel and has a thickness of less than about 12 mill. It is manufactured using a release film that is adapted in a number of ways to make release from the gel prior to use easier. In one method of making and using the thin gel gasket. it is applied to a joint which is subject to compression, in one embodiment, a lap joint of an aircraft fuselage.

Abstract:

A spacer and gasket assembly is shown for receipt between a static structure having a surface and fastener holes therethrough and a removable structure having a surface and fastener holes. The static structure and removable structure are engaged through a multiplicity of fasteners having a shaft diameter. The fasteners are adapted to apply a compression on the gasket between the static structure and the removable structure. The static structure and the removable structure have opposed, typically flat, facing surfaces. The spacer and gasket assembly comprising a substantially non-compressible spacer adapted for receipt between the static structure and the removable structure having a spacer thickness. A gasket has a sticky, deformable, flowable, elastomeric body and a skeleton having a skeleton thickness, the skeleton substantially integral with the body. The gasket has an uncompressed gasket thickness. The spacer and the gasket are adapted to be placed substantially between the facing walls of the static structure and the removable structure and the removable structure will compress and deform the gasket when the fasteners are torqued down.
