Abstract
Wood-plastic composites (WPC) , which were made of virgin high-density polyethylene (HDPE) with poplar fibers as filler, were measured by three vibration nondestructive testing (NDT) methods. The values of dynamic Young’s modulus of specimens were measured by different vibration NDT methods, and the values of static bending modulus of elasticity (MOE) were also determined by three point bending test according to ASTM D790-03. The paper analyzed the variability of the dynamic young’s modulus of WPC based on virgin HDPE obtained with different NDT methods, and the correlativity was also estimated between the dynamic Young’s modulus and the static MOE of WPC based on virgin HDPE. These results suggest that WPC can be made of virgin HDPE, and the NDT methods are appropriate to estimate the dynamic Young’s modulus of WPC based on virgin HDPE.
