Abstract
Moso bamboo has strong mechanical property and high economic efficiency. However, its anisotropy and inhomogeneity will increase the time and cost of mechanical properties testing. Aiming to solve this problem, in this paper, a series of tests were systematically carried out to test the parallel-to-grain compressive resistance, bending resistance, tensile resistance, shear resistance and perpendicular-to-grain compressive resistance, tensile resistance. Then, the characteristic values of mechanical properties of bamboo were analyzed for establishing the relationship between mechanical properties and density of bamboo and finding a kind of conversion method among mechanical properties. The results show that the parallel-to-grain properties of bamboo are better than that perpendicular to the grain. There is a high correlation between Mechanical properties and density of bamboo and can be well fitted by Linear functions. This research provides mechanical properties conversion parameters that can be used to evaluate and predict the properties of the moso bamboo.
