Current research in macro-meso-scale structure and mechanical properties of 3D-CF/Al composites

Three-dimensional woven carbon fiber-reinforced aluminum matrix composites (abbreviated as 3D-CF/Al composites) have higher specific strength, specific stiffness, impact damage resistance and crack expansion resistance due to the presence of a spatial mesh structure composed of continuous carbon fiber bundles inside. This paper reviews the effects of weave structure and preparation process parameters on the mechanical properties of 3D-CF/Al composites and the progress of research on meso-scale structure modeling and mechanical analysis, and proposes a theoretical concept of macro-meso-scale structure and mechanical synergy for the design, preparation and application of 3D-CF/Al composites in order to realize the digital design, manufacturing and performance of composites.
