    Abstract
  • The 3D printing manufacturing process and mechanical behaviors of “carbon fiber-graphene” (CF-G) reinforced thermoplastic polyurethane (TPU) composites were investigated. The CF-G reinforced TPU composite filaments were prepared by the screw extrusion process, then the G+CF/TPU composites were manufactured by the fused deposition modeling (FDM) technology and microwave post-treatment process. It shows that the CF-G heterostructure can synergistically enhance the mechanical properties of TPU composites. Especially, by adopting the novel microwave post-treatment process, the G+CF/TPU specimens exhibited the further improved tensile strength and toughness, which may be attributed to the promoted interface bonding between the reinforcing phase and matrix, and the reduced internal defects between points, layers, and channels induced by the synergistic effect between the CF-G heterostructure and microwave. This study has positive significance for exploring the mechanical reinforcement and post-treatment processes of 3D printed materials.
