The present disclosure relates to a composite article that may include a structural substrate, a multilayer fluoropolymer film that can include a high-melt fluoropolymer layer and a low-melt fluoropolymer adhesion layer that may contact the structural substrate and the fluoropolymer film. The high-melt fluoropolymer layer may have a melting temperature A1 and the low-melt fluoropolymer adhesive layer may have a melting temperature A2. The melting temperature A2 may be less than the melting temperature A1.

Multilayer composite article

A composite fabric laminate can include an open mesh fabric, a first continuous film comprising a fluoropolymer, and a second continuous film comprising a fluoropolymer. The fluoropolymer of the first continuous film and the fluoropolymer of the second continuous films can be in direct contact with one another. A method of forming a composite fabric laminate that includes disposing an open mesh fabric between a first continuous film and a second continuous film, each comprising an at least partially unsintered fluoropolymer film, to form a composite; laminating the composite at a pressure of at least 100 psig and a temperature of no greater than 350&#xb0; C.; and sintering the laminated composite to form the composite fabric laminate.

Architectural membrane

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.

Composites of fluropolymers with thermally non-adherent non-fluoropolymers

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 strengths of greater than 5 pounds/linear inch between the otherwise thermally non-adherent components.
