In this paper,structural and mechanical properties of composite plywood withbamboo sheet as face veneer on multi-layer poplar core veneer were investigated.It was alsoanalyzed that relationship between type of board structure,thickness of longitudinal bamboosheets,layer number of poplar core veneer,compression ratio of thickness and mechanicalstrength of the products. Results of the preliminary study showed that both MOR and MOEof the composite plywood were all higher than those of LVL made of poplar,and the MOEwas over that of bamboo plywood.The results indicated that the type of board structure re-markably affected properties of the composite plywood in bending. While thickness of outerlongitudinal bamboo sheets from 3.5mm to 5mm,compression ratio of thickness about 23%,the various mechanical properties were much better.
