Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

Abstract: A press felt 10 comprises a base body 30 and a batt layer having a wet paper side layer 20. The wet paper web side layer 20 has a base body side batt layer 22, upright fiber bundles 50 are formed in the basebody side batt layer 22.

Abstract: Plies of continuous fiber material are oriented and cut to the intended shape of a structural component, such as the vertical tail of an aircraft. Two skins or laminates are created by laying the cut-to-shape plies into a matched mold, with over-woven or over-braided mandrels or similar tooling details placed between the skins. The mold is closed and a thermosetting resin is injected into the mold to fully impregnate any fibers that were unimpregnated at the time of mold closure and to fully fill all void areas inside the mold. The mold is held closed with pressure, such as by a press, and heated to cure the resin while the resin in the mold is subjected to a hydrostatic pressure sufficient to constrain growth of voids. The contiguous faces of the impregnated braid or weave covering the mandrels are united by the resin, forming vertical or angular laminate between the inner faces of the skins.
