Abstract
A composite panel and its manufacture are described. Ultra-thick bamboo/wood and solid wood composite panels are comprised of core board, surface board and back board. The core board is composed of ultra-thick peeling veneers with thickness of 6 to 12 mm. Both surface board and back board are made of bamboo or wood. The core board comprises several layers of the ultra-thick veneers, and the veneers of contiguous layer are assembled with parallel structure. A glue layer is arranged between contiguous veneers; adhesive in the glue layer is aqueous macromolecule isocyanate adhesive. The ultra-thick veneers of the core layer are the veneers with stress degradation treatment, i.e., punctate or line segment cracks are formed along the grain of the veneer's loose side in each layer.
