TLDR
In this paper, the strength of closed-cell foamed aluminum is improved by adding pre-treated basaltfibers into aluminum or an aluminum alloy melt based on a melt foaming method.Abstract:
The invention relates to a preparation method for improving strength of closed-cell foamed aluminum and belongs to the field of porous metal materials. In order to overcome the defect that a closed-cell foamed aluminum material is non-uniform in pore structure and low in strength, the strength of the closed-cell foamed aluminum is improved by way of fiber strengthening by adding pre-treated basaltfibers into aluminum or an aluminum alloy melt based on a melt foaming method. The prepared closed-cell foamed aluminum material has the characteristics of being low in preparation price, simple in process, controllable in pore structure and strength and the like.read more
