Abstract:
The longitudinal tensile strength and the longitudinal tensile modulus of elasticity were investigated for moso bamboo (Phyllostachys pubescens) at different heights and radial positions. Results showed that the variation of the longitudinal tensile properties in the radial direction was greater than that in the longitudinal direction. The longitudinal tensile modules of elasticity ranged from 8.49 to 32.49 Gpa. The tensile module of elasticity in outer culm was about 3 to 4 times as high as that in inner culm. The longitudinal tensile strength ranged from 115.94 to 328.15 Mpa. The tensile strength in the outer is 2 to 3 times as high as that in the inner. Linear and curvilinear regressions were done from tested data of tensile strength and modulus and air-dried density in this paper. The linear equation worked a little better than the curvilinear one to predict the longitudinal tensile strength and tensile modulus from air-dried density.
