  • Patent number: 8663769
    Abstract: An oriented bamboo strand board and method for manufacturing the same are provided. The method includes: (a) cutting a bamboo stalk (4) into sections (6), and splitting each section (6) into 3-12 arc bamboo blanks (8) in the radial direction; (b) removing a outer surface part (10) and inner surface part (11) of the arc bamboo blank (8) by a thicknesser; (c) flaking the bamboo blank after removal of the outer surface part (10) and inner surface part (11) into bamboo flakes (14) with a thickness of 0.1-0.3 mm in the chordwise or substantially chordwise direction; (d) applying glue to the bamboo flakes (14) after drying, and orientedly spreading. The bamboo flakes have large width, break-resistance, good flatten characteristic and easy glue application, and the mechanical strength of produced oriented bamboo strand board is 1.5-1.6 times as much as that of the oriented bamboo strand board manufactured by radial flaking.
