- Abstract
The 3/2 unidirectional glass fiber metal laminates were developed using LY12-M aluminum alloy and HS2 high strength glass fiber prepreg by the hot pressing and curing progress. The fatigue crack propagation tests of LY12-M aluminum alloy plates and unidirectional glass fiber reinforced aluminum laminates were done. The result showed that the process of the preparing is feasible and the effective bridge stress of glass fiber was obtained. The fatigue crack growth rate of the laminates was 10-5～10-4mm/cycle, which was an order of magnitude lower than the LY-12 aluminum alloy. The crack opening shape was observed. The crack opening displacement of the glass fiber reinforced aluminum laminates were no obvious change , however, the crack opening displacement of the single layer of LY12-M aluminum alloy increased significantly with the propagation of fatigue crack.
