A novel forming method of wood is disclosed. In the method, a primary wood of which water content was adjusted in the range of 10-80wt% is brought into softened state, then said softened wood is compressed for forming with hydrostatic pressure by means of liquid as pressurizing medium, and then said compressed wood is treated with a fixation means of compressed state selected from either a step wherein a shaping jig or a mold is used, or heating in a particular temperature range is conducted for constraining volume relaxation of compressed wood, or cooling down below the softening point of said wood is conducted, or compact-packing together with hard particles into a vessel followed by heating is conducted, or a primary wood is chemically treated to form a localized wood-plastics composite before applying hydrostatic compression. Also, unique ligneous material obtained by the above-mentioned method or lumber sawn out from said material is offered.
Une nouvelle méthode de formage du bois est proposée dans laquelle un bois primaire dont la teneur en eau a été portée à 10 à 80 % en poids est ramolli; le bois ramolli est ensuite comprimé par pression hydrostatique au fins de formage; le bois à l'état de compression est ensuite stabilisé à l'intérieur d'un gabarit de formage ou d'un moule, ou soumis à un traitement de chaleur à des températures précises pour empêcher la détente du bois en compression, ou soumis à un refroidissement à une température inférieure à son point de ramollissement, ou soumis à une compression en contact avec des particules dures dans un récipient avant d'être soumis à une étape de chauffage, ou soumis à un traitement chimique pour former un composite localisé de bois et de plastique avant l'application de la pression hydrostatique. Une substance ligneuse unique tirée du sciage du bois soumis aux procédés décrits ci-dessus est aussi proposée.
