Abstract
The composite material has been widely used in aircraft structures. But this kind of material has some shortage such as poor impact resistance, low residual compressive strength, which have a negative influence on the performance of aircraft structures. In this paper, simulations of low-velocity impact and compression process of composite laminates with AL ply has been done. Finite element software ABAQUS/Explicit has been adopted to simulate the 3.5J impact and compression. A certain number of composite laminates with different thickness of AL ply has been tested, equal weight traditional composite laminates also been simulated as comparison. The simulation results show that AL ply with certain thickness can improve the residual compressive strength.
