Significant improvement in structural features, mechanical and physical properties of a novel CAR processed Al foam by nano-SiCp addition

A brief outline was prepared to study the effect of nano-SiCp reinforcement on the structural features, mechanical and physical properties of the continual annealing and roll-bonding (CAR) processed aluminum foam. Nanoindentation, drop weight impact and operational modal tests were applied to evaluate mechanical and physical properties of the nanocomposite foam. Scanning electron microscopy and elemental distribution images were utilized to analyze the results. Findings showed that the application of nano-SiCp results in matrix strengthening and remarkable improvements in dynamic compressive properties (strength increase of 48%), energy absorption (35% increase) and damping behavior (77% increase in damping ratio) of the nanocomposite foam.
