A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.

Composite and method for making

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.

A method for forming a material having an individually stabilized ply includes providing a ply having a non-orthogonal orientation. A stabilizing agent is then applied to maintain the orientation of the ply. The stabilizing agent could alternately be applied before forming the ply. The ply may be woven in a non-orthogonal orientation, or may have its orientation changed to the final non-orthogonal orientation. Changing may occur over multiple steps and may include using an accumulator and/or payout station to change the orientation.

Method and apparatus for forming fabrics and fabrics made by the method

A flexible composite includes a ply having a non-orthogonal orientation. The flexible composite may be a component of a flexible assembly. The flexible assembly may be any number of fabric-based assemblies such as a radome cover of a radome, a belt for an industrial machine, an expanision joint to connect ducts of a factory, and/or a roof or skylight of a structure (notably permanent structures). The ply may be individually stabilized by a stabilizing agent such as a matrix material. The ply may be woven and may include warp yarns and fill yarns.
