Abstract: A wood treatment composition for the preservation of wood comprises a mixture of creosote and a polymer which is miscible with the creosote at about 200° F. and does not substantially phase-separate when the wood treatment composition is under ambient conditions. The polymer may include, but is not limited to, ethylene vinyl acetate copolymers, ethylene methyl acrylate copolymers, ethylene ethyl acrylate copolymers, ethylene butyl acrylate copolymers, ethylene acrylic acid copolymers, ethylene methacrylic acid copolymers, ethylene methyl methacrylic acid copolymers, ethylene styrene interpolymers, styrene acrylic acid copolymers, styrene methacrylic acid copolymers, styrene methyl acrylate copolymers, styrene butadiene styrene block copolymers, styrene ethylene butylene styrene block copolymers, or a blend thereof. Preferably, the creosote is present in an amount of at least 50 percent by weight of the composition. Such compositions can be used to treat wood surfaces to prolong the service life of the wood.

Abstract: An apparatus and method are described for the formation of a three dimensional composite article by use of a flexible male mold placeable within a cavity formed within a rigid female mold. Fibers are initially bound to the surface of the flexible male mold and the mold is thereafter placed inside the female mold cavity. The surface of the flexible male mold is thereafter displaced away from the female mold by the injection of hardenable resin between the molds. The flexible surface is thereafter returned to near its original position adjacent the female mold. The flexible mold includes a chamber defined therein capable of pressurization and depressurization during the fabrication process of the composite article.
