Sandwich structural composites were prepared by aluminum foam as core materials with basalt fiber(BF)and ultra-high molecular weight polyethylene(UHMWPE)fiber composite as faceplate.The effect of factors of different fiber type faceplates,fabric layer design and the thickness of the corematerials on the impact properties and damage mode of aluminum foam sandwich structure was studied.The impact properties were also analyzed to compare with aluminum honeycomb sandwich structure.The results show that BF/alumi...
