Abstract: To produce a reformed medium density fiber (MDF) product, a reforming process is performed on a pre-finished MDF board having at least one pre-finished surface which, in turn, carries at least one coating. The process comprises the steps of: placing the pre-finished medium density fiber board in a heated press mold; closing the heated press mold while the pre-finished medium density fiber board is located therein; applying pressure and heat to the pre-finished medium density fiber board using the heated press mold so that the pre-finished surface(s) is (are) reformed without cracking, bubbling, or removal of the coating(s); opening the heated press mold; and removing the pre-finished medium density fiber board from the heated press mold. The application of pressure and heat preferably is such that the board becomes reformed, preferably no greater than 0.045 inch into the board.

Abstract: Containers made from wood chips 11 are made by forming a wall by pressing together wood chips 11 mixed with a water-insoluble adhesive 4. The wall permits infiltration of a liquid from at least one surface thereof and holds the liquid inside. The containers are suited for use as food bowls having a heat-insulating quality and as flower pots providing an automatic continuous feed of water. The wood chips used as the material are obtained by crushing particles of wood resulting from lumbering into smaller pieces.

Abstract: The present invention provides molded bodies made from a treated kraft pulp, the pulp having a high hemicellulose content or at least 7% a low copper number of less than 2, and including cellulose that has a low average degree of polymerization (D.P.) that has a range of 200 to 1100.

Abstract: Multi-fiber composites consist of a combinant structure of cellulosic wood and/or non-wood or polymeric fibers which are mixed with non-fibrous waste materials and processed to form Pseudo-Fiber™ natural fibers. They offer economic and environmental efficiencies to wood, non-wood papermaking, polymeric and other composite operations. They also provide useful, multivarious functional fiber properties necessary or desired in the manufacture of, but not limited to, automotive, disposable cups, food and non-food packaging; disposable hygiene products of diapers, feminine care, incontinence; disposable medical products of wound dressings, surgical gowns and drapes; personal care and filtration products.

Abstract: A wood composite board or panel, such as particleboard, fiberboard, oriented strand board or waferboard and a method of producing the same. The composite board or panel comprises a plurality of wood pieces, thermoset resin to bind the wood pieces and a filler having a high thermal conductivity. Examples of such a filler include natural and synthetic graphites, metal, carbon, silicon carbide and other similar compounds and their mixtures.

Abstract: A decorative sheet arranged on the outside or inside of buildings is composed of a compression-molded core made from one or more core layers. The core contains cellulose fibers or wood fibers, bound to one another by a hot-curing resin. Each core layer is composed of wood fibers or of cellulose fibers having lengths from 0.3 to 30 mm, and is containing pigments or is without pigments. The pigments are uniformly distributed within the core layer, and their proportion by weight is from above 0 to 20% by weight of the mixture made from pigments and from wood fibers or cellulose fibers. The pigments are colorfast, and weathering of the wood fibers or cellulose fibers at the surfaces of the sheet causes the original coloration of the core surfaces to change so that, when dry, the core is covered by a gray-silver patina, but substantially regains its original coloration when wet.

Abstract: The invention is directed to a method of selectively coating wood composites in a single step, while maintaining registration of the coating to the design of the molded or contoured wood composite. The invention also is directed to a structure provided by preparing a wood composite according to the inventive method.

Abstract: The present invention relates to a wood-polymer composite, particularly wood which has been impregnated with a mixture containing polymerizable organic compounds, and more particularly to a method for preparing a wood-polymer-composite by impregnating wood material and/or wood-based material with a mixture containing polymerizable organic compounds, and most particularly uses thereof.

Abstract: The first group of the present invention is a wood reinforcing carbon fiber prepreg, which is produced through impregnation with a mixture resin at a viscosity of 3 to 150 poises at 20° C., wherein the mixture resin contains one or more resins selected from resorcinol based resins and resol type phenol based resins, formaldehydes as curing agents and inorganic acids or organic acids as curing catalysts. The first group of the present invention is a wood reinforcing carbon fiber prepreg having a longer usable time and being capable of imparting the rigidity and elastic modulus of carbon a fiber to the wood to be reinforced at a high ratio. The second group of the present invention is a wood reinforcing carbon fiber prepreg attached wood based sheet, wherein a wood based sheet of a thickness of 0.01 mm to 0.06 mm is arranged on at least one face of a carbon fiber prepreg sheet produced through impregnation with a mixture resin containing a thermosetting resin and a curing agent or a curing catalyst.

Abstract: Two types of synthetic resin are used with zephyrs 2 made from a wide range of bamboo canes from undried to dried. An appropriate amount of special thread 4 comprising a core thread 5 having a high melting point and a core-thread covering skin 6 having a low melting point are added to the zephyrs and kneaded together. When molding the kneaded material, it is heated to the temperature at which the skin starts to melt and pressed. Then the skin works as a binder that binds the zephyrs and the core thread. The core thread supplements the strength and the flexibility of the bamboo zephyr board.

Abstract: A method of impregnating wood with liquid puts the wood in a pressure vessel, immerses the wood in the liquid contained in the pressure vessel, pressurizes the liquid to compress the wood while keeping the temperature of the wood at or above the softening point of the wood, and reduces pressure in the pressure vessel so that the wood may cause volume relaxation in the liquid and be impregnated with the liquid.

Abstract: Fiber reinforced brittle matrix composites are disclosed with improved mechanical properties. The composites comprise extensible, somewhat elastic fibers and hardened brittle matrix materials. The fibers are positioned to support the composite in a three dimensional manner. Temporary tension forces are applied to some of the fibers before the matrix has completely hardened. The resulting three dimensional array of aligned fibers acts to improve the properties of the composite by providing self-compression. Self-compression is enabled by the alignment and stored elastic energy resulting from the temporary tension and from other deformations acting with the fiber network. The composites have improved response to challenges such as matrix shrinkage during hardening or bending forces and impacts. The invention is particularly useful with brittle, high modulus matrixes, such as cementitious materials and elastic fibers such as polymeric fibers.
