Impact damage research of sandwich composite laminates

摘要：

　　Sandwich composite laminates structure is a classic application of composite material on actual aircraft structural.Dealing with low-velocity impact damage and residual compressive strength of sandwich composite laminates,explicit finite element method of ABAQUS/Explicit software was adopted to simulate low-velocity impact and compression process.Impact response and invalidation on compression between sandwich composite laminates with different core materials and regular composite laminates were compared.The simulation results indicated that softer core materials can absorb more impact energy,reduce the structure damage and enhance the residual compressive strength after impact.
