  • Publication number: 20070132133
    Abstract: The invention provides a method for manufacturing a resin composite formed product for easily producing a resin composite formed product at a high precision by easy forming. The method is for producing a resin composite formed product (31, 31?) with a plate-like or prescribed three-dimensional shape by using a composite material (30, 30?, 30?) obtained by bonding a filler-like, powder-like, granular, flaky, or bulky raw material with a binder resin, crushing the composite material, arranging the crushed fragments of the composite material on a plane or a prescribed three-dimensional face, softening or melting the binder resin under pressurizing condition, and curing the binder resin. Wood pieces or a hydrated metal compound may be used as the composite material. A biodegradable resin may be used as the binder resin.

  • Publication number: 20050116377
    Abstract: A manufacturing method of composite wood that arbitrary amount of wood can be used, nailing is possible and a product with arbitrary configuration is easily manufactured is provided. A melted binder resin and a plurality of wood pieces are kneaded. Then, a resultant kneaded material of the wood pieces and the binder resin is strongly pressed. The binder resin is cooled while the kneaded material is strongly pressed. Alternatively, strong pressing and cooling are repeated for the kneaded material. As a result, the binder resin is cured. A resultant composite wood is cut into a board with a predetermined thickness or a bar with a predetermined dimension and assembled into a desired product. A water content of the wood pieces may be evaporated by heat from the binder resin or may be evaporated by heating the wood pieces.
