Xunchi Fang, Lewei Hou, Zhiji Liu — Polymer Composites · ABSTRACT With the rapid development of the wind power industry, the efficient recycling of decommissioned wind turbine blades has become an urgent environmental challenge. In this study, mechanically crushed wind turbine blade waste (WTBW) is used as a filler in poly(vinyl chloride) (PVC) and its wood–plastic composites (WPC). Specifically, WTBW powders with different sizes are obtained by simply crushing and sieving. The effects of WTBW size, content, residual epoxy resin, and surface modification on the composites' properties are investigated. After incorporating 10% WTBW of 100–200 mesh, the tensile strength and Young's modulus of the PVC composite increase by 4.0% and 25.2%, compared with neat PVC. At a loading of 15%, the flexural strength and flexural modulus show the maximum increases of 12.3% and 16.7%. The residual epoxy resin on the glass fiber surface serves as an interfacial
