ELASTOMERIC GASKET HAVING A FOAM METAL SKELETAL MEMBER

摘要

A gasket for compressible placement between a first surface and a second surface is disclosed. In one embodiment, the gasket has a cellular metal skeleton embedded in a viscoelastic, pliable, deformable tacky polymer body. The skeleton has multiple strands, which connect to form multiple interconnected cells or pores. The skeleton, prior to being encapsulated in the tacky polymer body, is typically about 75% or more void space. The void space is substantially filled in the manufacture of the gasket, with the tacky uncured polymer. The uncured polymer will set up or cure, and then the gasket may be used.

1. A gasket for compressible placement between a first surface and a second surface, the gasket comprising:
a viscoelastic, pliable, deformable, tacky polymer body; and a cellular metal skeleton embedded in the body, the skeleton having multiple interconnected strands, some of the strands meeting at nodes, the strands and nodes defining multiple interconnected cells or pores, the skeleton having a pore density which may be measured in an x, y and z dimension, the z axis being the shortest axis and normal to the x and y axis and the first and second aircraft surfaces and defining a skeleton thickness, the skeleton having a relative density of less than about 25%.
