Abstract: This study explores the preparation and mechanical properties of aluminum-clad core carbon fiber reinforced aluminum matrix (CF/Al) composite dovetail joints. T700-12K carbon fiber and ZL207 aluminum alloy were utilized, and infiltration tests were performed at various temperatures ranging from 660℃ to 715℃ using a liquid-solid infiltration extrusion process. The results indicate that increasing the infiltration temperature significantly enhances the tensile strength (154 MPa) and shear strength (88 MPa) of the specimens. Particularly within the temperature range of 690℃ to 715℃, the composite demonstrated a uniform distribution of carbon fibers with no significant defects present. The study also analyzed the influence of temperature gradients on infiltration behavior, revealing that optimized infiltration pressure (45 MPa) and appropriate temperature contribute to improved infiltration quality. The testing results demonstrate that the prepared composite materials possess excellent mechanical properties and good processing adaptability, providing a reliable basis for their practical applications.
