ELASTOMERIC GEL BODY GASKET HAVING A SUBSTANTIALLY INCOMPRESSIBLE SKELETON, A METHOD OF MAKING AND USING THE SAME

摘要

Gaskets, including aircraft gaskets, are disclosed, the gaskets having an elastomeric gel body and substantially incompressible skeletons. The bodies may be pliable and deformable and, in one example, may be comprised of a two-part chemically cured polyurethane that sets up as a gel after mixing with the web so that it is fully integral with the web and so that there is substantially no air bubbles or air pockets left in the web. The web may be a regular shaped web and made of nylon.

主权项

1. A gasket or gasket tape for interposition between a moveable aircraft workpiece and a stationary platform, the gasket comprising:
a pliable, elastomeric gel body having an upper surface, a lower surface, and a perimeter; and a non-metallic, non-fibrous, electrically non-conductive, non-woven molded or extruded skeletal web having an upper surface, a lower surface, a perimeter and a multiplicity of strands meeting at and integral with a multiplicity of joints, the strands and joints defining a multiplicity of open pores; and a first foam layer;
wherein the elastomeric gel body is the same size or thicker than and substantially encapsulates the skeletal web, including filling the pores thereof, and is integral therewith; andwherein an x and y dimension is much greater than the z (thickness) dimension; andwherein the gasket is configured for lateral gel flow under compression between the workpiece and base, such compression in the range of about 50-500 psi, wherein such compression fails to cause substantial permanent deformation of the skeletal web.
