Abstract
A gasket or tape material for sealing between two members. The gasket or tape material, in one embodiment, includes a skeletal member and/or metallic and/or non-metallic particles. Enclosing the skeletal member and/or particles is a flexible, compressible resilient polyurea body member having a tacky outer surface, the tacky outer surface for engagement between the two members. The resilient body may be comprised of polyurea. The skeletal member may be comprised of a metallic or a non-metallic material, woven or non-woven metallic or non-metallic.
Claims25
A gasket or tape for sealing between two members, the two members under compression and being two parts of an aircraft, the gasket material comprising:
- a flexible skeletal member;
- and
- a flexible, deformable, elastomeric resilient polyurea body member having a tacky outer surface, the body member for substantially enclosing the skeletal member with a self-curing mix of an isocynate component and an amine terminated component, the resilient body member having a tacky top surface and a tacky bottom surface.
An assembly comprising:
- a first aircraft part having a first surface;
- a second aircraft part having a second surface;
- a gasket or gasket tape for placement between the two parts, the two parts under compression, the gasket or gasket tape material comprising:
- a flexible skeletal member;
- and
- a flexible, deformable, elastomeric resilient polyurea body member having a tacky outer surface, the body member for substantially enclosing the skeletal member with a self-curing mix of an isocynate component and an amine terminated component, the resilient body member having a tacky top surface and a tacky bottom surface;
- and
- fasteners for engaging the two parts and providing compression on the gasket or gasket tape.
A method of making a gasket or gasket tape, the method comprising the steps of:
- laying a skeletal member on a flat, release/support surface;
- combining an uncured, a self-curing, two part, gas bubble-free, polyurea mix onto the skeletal member, such that the mix substantially encapsulates the skeletal member before curing;
- allowing the mix to cure;
- and
- shaping the encapsulated skeleton to the shape of a workpiece.
