WOOD COMPRESSING/PERMANENT-FIXING METHOD AND CONSOLIDATED WOOD

摘要

A wood compressing/permanent-fixing method which compresses wood and permanently fixing the compressed condition by heat-treating without drying, for practical use as lumber. A method of producing consolidated wood by heat-treating compressed wood in a consolidated condition and fixing the consolidated condition, characterized in that air-dried wood containing 12% of water is used as wood to be compressed, the air-dried wood housed in a compression mold in contact with the inner wall surface of the mold is compressed at a compression ratio of at least 50% to form compressed wood, then the compressed wood retained in the compression mold in a consolidated condition is heat-treated while kept air-tight so as to fix the compressed condition of the compressed wood.
