Abstract

A composite of thermally non-adherent fluoropolymeric and non-fluoropolymeric components is created through the agency of a non-woven, fibrous binder interposed between and portionally embedded into both components. The fibers of the non-woven binder have a substantial portion of their length extending into both components and cross the interface at an angle that is substantially normal to the plane of embedment. The composite possesses good peel-adhesion behavior between the otherwise thermally non-adherent components.
