    Abstract: A sizing composition that permits in-line chopping and drying of reinforcement fibers for reinforcing thermoset resins is provided. The size composition includes at least one coupling agent and one or more blocked polyurethane film forming agents. The blocking agent preferably de-blocks at a temperature that permits simultaneous or nearly simultaneous de-blocking and curing of the polyurethane film former. The sized fiber strands may be chopped to form chopped strand segments and dried in a fluidized bed oven, such as a Cratec® drying oven, in-line. The chopped fiber strands may then be used in a bulk molding compound and molded into a reinforced composite article. Chopping the glass fibers in-line lowers the manufacturing costs for products produced from the sized fiber bundles. Further, because the reinforcement fibers can be chopped and dried at a much faster rate with the inventive size composition compared to conventional off-line chopping processes, productivity is increased.

  • Publication number: 20110248422
    Abstract: The present invention relates to a method for the production of tungsten carbide based cemented carbide or cermet tools or components using the powder injection moulding or extrusion method comprising mixing of granulated cemented carbide or cermet powder with an organic binder system whereby the mixing is made by adding all the constituents into a mixer heated to a temperature above the melting temperature of the organic binders. According to the invention the organic binders are added into the mixer, waiting for a melt to form and then slowly adding the cemented carbide or cermet powder into the melt, making sure the temperature does not fall below the melting temperatures of the organic binders.

  • Publication number: 20110248421
    Abstract: A fiber cement composite material that incorporates a blend of bleached and unbleached cellulose fibers as a partial or complete substitute for premium grade cellulose pulp is provided. Bleached standard grade cellulose fibers are used in conjunction with unbleached, standard grade cellulose fibers to provide a fiber cement composite product having substantially equal or even superior flexibility and strength as an equivalent fiber cement composite material reinforced by premium grade, unbleached cellulose fibers. A synergistic combination of bleached and unbleached standard grade cellulose fibers to produce a composite material with the desired properties previously achievable only through the use of premium grade cellulose pulp.

  • Publication number: 20110250461
    Abstract: Methods are disclosed in which two or more forming chambers are used to process inorganic fibers by gravity-laying methods. The methods may comprise using a first forming chamber to open inorganic fibers and using a second forming chamber to process the opened inorganic fibers, optionally to blend the opened inorganic fibers with additional inorganic fibers and/or with particulate additives, and to collect the inorganic fibers as a mat. The methods may comprise using a first forming chamber to form a first inorganic fiber layer and a second forming chamber to form a second inorganic fiber layer, and consolidating the first and second inorganic fiber layers so as to provide a multilayer gravity-laid inorganic fiber web.

  • Publication number: 20110251306
    Abstract: Wax is a key ingredient in engineered wood composites, such as oriented strand board (OSB) and oriented strand lumber (OSL), to prevent and reduce swelling caused by water uptake. Wax, normally a byproduct of oil refining and lube production, is now considered a precious feedstock for producing higher margin product such as fuel or diesel. Disclosed herein are suitable alternative waxes to petroleum wax for use as sizing agents in producing engineered wood composites.

  • Patent number: 7988896
    Abstract: A method of preparing a carbon nanotube/polymer composite material is provided. The method includes (a) providing a carbon nanotube-based film and a pre-polymer solution; (b) placing the carbon nanotube-based film at a bottom of a container, and pouring the pre-polymer solution in the container; and (c) polymerizing the pre-polymer solution and simultaneously integrating the pre-polymer solution with the carbon nanotube-based film. As such, a carbon nanotube/polymer composite material, including the polymer-impregnated nanotube layer and an upper polymer layer, is obtained. A multi-layer composite can be produced by essentially repeating this process, using the upper polymer layer as the base layer for the formation of the next layer set thereon.

    Abstract: A block of dense material is made up of hard particles, of the same or different nature, dispersed in a binder phase. The material has a solidus temperature Ts above which the binder phase is liquid. There is deposited on at least a portion of the surface of the block of dense material an active coating composed of a material capable of reacting chemically with the dense material when the assembly is heated to beyond a minimum reaction temperature Tr. The block coated with the active coating is subjected to a heat treatment comprising heating, then maintenance for a time tm at a maintenance temperature Tm greater than or equal to the minimum reaction temperature Tr, followed by cooling to ambient temperature.
