ABSTRACT:
A composite gasket including facing material and a core material. The core material includes tanged portions which are formed by disturbing a surface of the core. The tang portions preferably terminate into pointed tips which penetrate the facing material when it is forced against the tangs. When sufficient force is applied against the facing material, the pointed tips of the tangs deform inwardly forming hook shaped ends. These hook shaped ends help form and maintain an excellent mechanical bond between the core material and the facing material. The forming of the tangs does not penetrate completely through the thickness of the core material but simply forms a slight divot in the surface of the core material. Thus, there is no possibility of leakage through the core material.
