Impact Resistance Research of Composite Laminate Structure

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 and different core material has been done. The simulation results show that softer core materials and AL ply with certain thickness can improve the residual compressive strength
