　　Foam core sandwich structures are integral constructions consisting of two composite facesheets and a lightweight foam core.Since they have excellent mechanical properties, application of foam core sandwich structures to primary aircraft structures is expected.However, since the composite facesheet is very thin and the lightweight foam core is weak, they can be easily damaged when an impact or indentation load is applied.The facesheet locally deflects and the core is crushed.
