摘要
Fibre-metal laminates(FMLs) that consists of three layers of 2024-T3 aluminium alloy sheets and two layers glass/epoxy composite were studied in this work. The specimens were designed and produced. Low-velocity impact tests were performed successfully on FMLs, using an instrumented falling weight machine. For comparison purposes, similar tests were set up and were carried out on monolithic 2024-T3 sheets. Damage mode and feature of them were compared and studied. ABAQUS software was used to simulate dynamic response and damage evolution of FMLs during impact. It is shown that FMLs have better impact resistance properties than pure aluminum sheets because of the fibre. The damage of FMLs has three clear different steps to damage during impact. The simulation and experiment results agree well with each other.
