Effect of graphene nanoparticles on the strength of sandwich structure inspired by dragonfly wings under low‐velocity impact

Dragonfly's wings are highly specialized flying organs that are well adapted to the flying behavior of each dragonfly, mainly consisting of veins and membrane. The effect of graphene nanoparticles on a novel foam‐based sandwich panel structure inspired by microstructural features of dragonfly wings has been investigated under low‐velocity impact. Composite and nanocomposite sandwich veins are made of E‐glass/epoxy layers, in which different...
