Study on compressive property of aluminum foam with particle-reinforced Al alloy matrix

Closed-cell aluminum foam with particle-reinforced Al alloy matrix was prepared by method of melt foaming,then the quasi-static and dynamic compression experiments were carried out.The results were compared with that of Al alloy matrix aluminum foam.The quasi-static and dynamic compressive properties of aluminum foam with different relative densities were investigated,and it was found that adding particles can reinforce the performance of matrix alloy and improve the compression effect of foam.Results indicate that in the quasi-static and dynamic compression experiments,the plateau stresses and Young's modulus both increase with the increase of relative density,and energy absorption capability under dynamic compression condition is larger than that under quasi-static compression condition.Adding fly ash particles with appropriate proportion in melt can significantly enhance the effect of the matrix,and effectively improve the compression performance of aluminum foam.
