Dynamic and Static Properties of Wood-Plastic Composites Made of Recycled High-Density Polyethylene

Abstract:

Three different nondestructive testing (NDT) methods were used on the wood-plastic composites (WPC), which were made of either recycled or virgin high-density polyethylene (HDPE) with poplar fibers as filler. The values of dynamic Young’s modulus of WPC based on recycled or virgin HDPE were measured by the different 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 recycled or 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 recycled HDPE. These results suggest that WPC can be made of recycled HDPE, and the NDT methods can be appropriate to estimate the dynamic Young’s modulus of WPC based on recycled HDPE.
