Abstract
An extrusion resistant gasket may have a metallic core having a first side and a second side. The metallic core may have a plurality of alternating domes and valleys integrally formed therein. The domes and valleys do not have perforations through the core. The gasket may also have a non-metallic facing material on at least one of the sides of the metallic core. The facing material may have a contact surface and an inner surface. The domes or valleys do not extend through the contact surface.
Claims17
An extrusion resistant gasket, comprising:
- a metallic core having a first side and an opposing second side, wherein the metallic core has a plurality of alternating domes and valleys integrally formed therein, and wherein the domes and valleys do not perforate the core;
- a non-metallic facing material on at least one of the sides of the metallic core, the facing material having a contact surface and an inner surface, wherein the inner surface is interlocked with the metallic core, and wherein the domes and the valleys of the metallic core do not extend through the contact surface;
- and
- an adhesive disposed between the metallic core and the inner surface of the facing material on at least one of the sides of the metallic core.
A method for forming an extrusion resistant gasket, the method comprising:
- providing a metallic core layer having a first surface and an opposing second surface;
- providing a non-metallic facing layer on at least one of the sides of the metallic core layer, the facing material layer having a contact surface and an inner surface;
- mechanically interlocking the inner surface to the metallic core layer;
- forming a plurality of alternating domes and valleys within the metallic core layer, wherein the domes and valleys do not perforate the metallic core layer;
- pressing the non-metallic facing layer against the plurality of domes so that the non-metallic facing layer assumes a complimentary shape to the plurality of domes;
- and
- bonding the non-metallic facing layer with the metallic core layer.
