Compressive Properties of Advanced Pore Morphology Aluminum Foam Filling Square Tube

Composite square tube was prepared by taking advanced pore morphology (APM) aluminum foam units as core material and square aluminum tube as panel material, then the quasi-static compression testing was performed, and the comparison between the APM aluminum foam and square tube with the traditional ones. The results show that the compression performance of APM foam aluminum units and traditional foam aluminum was not very different, and that of APM aluminum foam units fulling square tube and traditional ones also was little difference. The compressive properties of the filling square tube was improved significantly by the interaction of APM foam aluminum units square aluminum tube, and the deformation style of the filling square tube was also changed. So, APM aluminum foam units could be used for preparating complex aluminum foam sandwich structure materials.
