Study on the low-velocity impact response of foam-filled multi-cavity composite panels
Abstract This paper investigates the influence of lattice-web layout on the low-velocity impact performance of foam-filled multi-cavity composite panels (FMCPs). The effect of impact velocity has been explored to demonstrate the impact resistance property and energy absorption capacity. Due to the light weight and great energy absorption capacity, the FMCP with double-layer dislocation webs can be used as a good energy buffer device. An energy balance model, based on the energy absorption during impacts, was developed to predict the peak loads of the FMCPs. Numerical models were established and parametric analysis was conducted on the GFRP thickness and foam density.

Highlights Sandwich structures are appealing to anti-collision devices but existing drawbacks. A novel foam-filled panel had great impact resistance and energy absorption capacity. An energy balance model was used to predict the peak loads of the foam-filled panels. Numerical models were established to conduct parametric analysis.
