  ABSTRACT: In this study, carbon fiber (CF) reinforced magnesium matrix composites were used as the research object. Composites with micro-macro cross-scale layered configurations were designed and prepared by powder metallurgy sintering process. The tensile test results show that when the carbon fiber content is 1.2 wt.% and the thickness of the single-layer composite is 3.5 mm, the material exhibits excellent strength-ductility matching: the tensile strength is 269 MPa and the elongation at break is 14.7%, which achieves good plasticity while significantly improving the strength. The study further systematically analyzed the synergistic contribution of traditional strengthening mechanism and back stress strengthening to material strength, and revealed the improvement effect of carbon fiber on material plasticity through internal ductility mechanisms such as “pulling out”, as well as external energy dissipation pathways such as crack deflection. This work provides a new structural design idea for simultaneously improving the strength and ductility of magnesium matrix composites, and has important reference value for the optimization of its comprehensive mechanical properties.
