采用FSP工艺制备了泡沫铝夹层结构。在该方法中，可发泡前体的制造和前体与致密钢板之间的冶金结合可以同时进行。虽然生成了由Fe2Al5和FeAl3组成的金属间化合物，但拉伸试验表明，与孔隙率约为80%的泡沫铝的拉伸强度相比，界面的结合强度相对较高。
An aluminum foam sandwich was fabricated by FSP route. In this process, both the fabrication of a foamable precursor and the metallurgical bonding between the precursor and a dense steel sheet can be simultaneously conducted. Although intermetallic compounds consisting of Fe2Al5 and FeAl3 were generated, tensile tests revealed that the bonding strength of the interface was relatively high compared with the tensile strength of the aluminum foam with a porosity of approximately 80%.
