摘要

Studies have been reported on recycling high-density polyethylene (HDPE) for various applications. However, little has been reported on the secondary (2°) recycling of HDPE with reinforcement of SWP by fused filament fabrication (FFF) for structural applications. This study highlights the FFF of 2° recycled HDPE-SWP composites by varying infill percentage (IP), infill type (IT), and nozzle temperature (NT). The study suggested that NT is one of the most crucial factors for maximizing elastic modulus (E). The best settings for FFF are 100% IP, triangle IT, and 215 ℃ NT for maximum E. The study also suggests that higher NT improved the crash resistance of the selected composite.
