... 638,350. Compound sheet materials. JENKINS, D. V.; and UNIREP, Ltd. June 20, 1946, No. 18528. [Class 140] Laminated materials are made by soaking or impregnating thin sheets of wood such as balsa wood in a volatile liquid and, after removal of each sheet from the liquid but whilst it is still wet, applying to one or both of its faces a solid film of a tough and pliable material which is soluble in the liquid, the material being then dried at room or elevated temperature and with or without pressure. The volatile liquid may be acetone and the film may be cellulose acetate, celluloid, or polymethyl methacrylate. While still wet the laminated material may be cut to shape, e.g. with a guillotine, or moulded. When a moulded article is to be formed, wooden inserts or strengthening pieces may be applied to the initial wood sheet by gluing, and when the sheet is to be moulded into tubular form, the adjoining edges may be united by gluing or stapling.

Wood is softened by impregnation with hydrazine whereupon it may be readily shaped and the hydrazine removed, leaving the wood stable in its new shape. The final wood is harder than the original; this may be enhanced by compression. Hydrazine recovered, e.g. by pressing or heating, may be reused. The hydrazine may be used pure or in, e.g. aqueous solution. Vacuum and/or pressure may be used to assist impregnation, or the hydrazine may be applied by brushing. A heating step increases the plasticity of the impregnated wood.

Polymerising wood-impregnating monomer

Wood with increased water-impermeability and abrasion-resistance is produced by impregnating thin layered cellulose-contg. materials, pref. wood (veneer) or paper, with monomers and polymerising while wood layers are clamped in a press under tension, pref. by radiation or catalyst. Pref. before impregnation the thin materials are stacked plane parallel on top of one another. Foils of material inert to monomers are inserted between the thin materials, pile is clamped in a press and impregnated with monomers while clamped. After impregnation pile is packed air-tight with material inert to monomers and polymerisation is carried out under tension.
