Article Preview

The tensile mechanical properties of bamboo mat and curtain plywood(for short bamboo plywood)were studied through “electrometric method”. It was proved that in the range of elastic deformation,the Poisson′s ratio and the elastic modulus of the bamboo plywood were not constant. The Poisson′s ratio of the bamboo plywood decreased nonlinearly with the load increase that Poisson′s ratio decreased markedly when the load was less than 1kN,and decreased gently when more than 1kN.The tensile elastic modulus of the bamboo plywood also increased nonlinearly with the load increase that the tensile modulus of elasticity increased drastically when the load was less than 800N,and increased less when exceeded 800N. In the process of loading,the tensile deformation、the tensile stress and strain all increased linearly with the load increase,and the tensile stress and strain both were linearly relevant to tensile deformation.
