A composite article is provided for use as a heat spreader, a cooling element or as part of the heating system for a wide variety of items. The composite article can include at least one sheet of compressed particles of exfoliated graphite or graphiiized polymer. A protective coating may be aligned or adhered with a surface of the sheet. The article may also include at least one of a fiber reinforced polymer, a fiber weave or fiber mat or combinations thereof, aligned with at least one of the first surface of the sheet or a second surface of the sheet. The composite article can include a plurality of strips of compressed particles of exfoliated graphite, of graphiiized polymer or combinations thereof, which are woven together and/or it can Include cut outs, slits or other perforations to provide flexibility, stretehabi Kiy, and breathability.

The composite article can include at least one sheet of compressed particles of exfoliated graphite or graphitized polymer. A protective coating may be aligned or adhered with a surface of the sheet. The article may also include at least on of a fiber reinforced polymer, a fiber weave or fiber mat or combinations thereof, aligned with at least one of the first surface of the sheet or a second surface of the sheet. The composite article can include a plurality of strips of compressed particles of exfoliated graphite, of graphitized polymer or combinations thereof, which are woven together and/or it can include cut outs, slits or other perforations to provide flexibility, stretchability, and breathability.

A method for preparing resin-impregnated graphite articles, including providing a sheet of compressed particles of exfoliated graphite having two major surfaces; impregnating the sheet with a first resin system to form a resin-impregnated sheet; surface treating the resin-impregnated sheet to form at least one structure on at least one of the major surfaces of the sheet to form a surface treated sheet; and treating the sheet with a second resin system.

Dimensionally stable, leak-free graphite substrate

A process for preparing a gas permeable flexible graphite sheet is presented. The process includes providing graphite flakes; admixing the graphite flakes with a sacrificial additive to form a graphite mixture; compressing the graphite mixture into a sheet having sacrificial additive dispersed therethrough; and treating the sheet to at least partially remove the sacrificial additive to form a permeable flexible graphite sheet.
