| Abstract Scope |
Polycarbonate–carbon fiber (PC-CF) composites fabricated through material extrusion additive manufacturing offer high strength, thermal resistance, and lightweight characteristics for engineering applications. However, residual stresses and weak interlayer adhesion developed during the printing process can negatively affect mechanical performance and dimensional stability. This study investigates the effect of post-processing thermal annealing on the mechanical and structural behavior of 3D printed PC-CF composites. Printed specimens were annealed at different temperatures under controlled conditions and evaluated using tensile, hardness, and impact testing. Dimensional changes and fracture behavior were also analyzed to assess the influence of annealing on structural integrity. The results are expected to demonstrate that moderate thermal annealing improves interlayer bonding and mechanical performance through stress relaxation and enhanced polymer chain mobility, while excessive annealing may introduce warpage and dimensional deformation. The findings provide practical guidelines for optimizing thermal post-processing conditions in high-performance thermoplastic composite additive manufacturing. |
