Relativity Analysis between Dynamic and Static Modulus of Elasticity on Different Thickness Wood-plastic Structural Plates

摘要：

　　The relativity was evaluated between dynamic modulus of elasticity (MOE) and static MOE,in order to assess the potential of using nondestructive testing (NDT) method as a checking tool for mechanical properties of wood-plastic structural plates.The dynamic MOE was evaluated on a FFT system,and the static MOE was determined by three point bending test.All of specimens were made of polyethylene (PE) and poplar flour.A significant correlation between the dynamic MOE and the static MOE was obtained from relativity analysis.These results suggest that the NDT method could be appropriate to estimate the dynamic MOE of specimens with different thickness.
