Abstract
An abrasive-erosion resistant head gasket assembly includes a flat-elongated core, a sheet of composite gasket material on each face of the base, armor to seal the combustion chambers, and bodies of abrasive-erosion resistant elastomeric material at each end of the gasket assembly. The abrasive-erosion resistant bodies are selectively applied to the end zones of the gasket assembly where abrasive-erosion is normally at a maximum. The bodies resist abrasive-erosion. The bodies are applied to the facing material or in zones from which the facing materials have been removed and preferably are cured concurrently with the lamination and curing of the facing materials.
