Low Velocity Impact Properties of Aluminum Foam Sandwich Structural Composite
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 corematerial...

| 要約: | 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/aluminum foam sandwich structural composites has bigger impact damage load than UHMWPE/aluminum foam sandwich structure, but less impact displacement and energy absorption. The inter-layer hybrid fabric design of BF and UHMWPE has higher impact load and energy absorption than the overlay hybrid fabric design faceplate sandwich structure. With the increase of the thickness of aluminum foam,the impact load of the sandwich structure decreases, but the energy absorption increases. Aluminum foam sandwich structure has higher impact load than the aluminum honeycomb sandwich structure, but smaller damage energy absorption; the damage mode of aluminum foam core material is mainly the fracture at the impact area, while aluminum honeycomb core has obvious overall compression failure. |
