Horizontally Sectioned Polymer Gasket

Abstract

A gasket is disclosed for use as an environmental seal between a first aircraft part having planer surface and a second aircraft part having a planer surface, the two planer parts spread apart and engaged with fasteners. The gasket, in some embodiments, is compressible between the planer surfaces. The gasket, in some embodiments, comprises a first tabular portion having tabular portion properties and having a first tabular thickness and a length and a width, the length and width much greater than the first tabular thickness; and a second tabular portion having tabular portion properties having a second tabular thickness, a length and width, the length and width much greater than the second tabular thickness; and a tabular skeleton. The first and second tabular portions and the skeleton are positioned parallel to one another. The skeleton is at least partly contacting one of the tabular portions. The first tabular portion and the second tabular portion differ in at least one tabular portion property.

1 . A method for making an elastomeric seal between a first aircraft part and a second aircraft part, the method comprising the steps of:
 first providing a mold;   second providing a skeleton, the skeleton having some open pores;   placing the skeleton in the mold;   first introducing a first uncured polymer mix into the mold;   second introducing a second uncured polymer mix into the mold;   first allowing this first uncured mix to at least partially cure;   second allowing the second uncured mix to at least partially cure;   wherein the first uncured polymer mix and the second uncured polymer mix cure to a mix having at least one differing property and;   wherein at least one of the introducing steps results in contacting the uncured polymer mix with the skeleton.
