An experimental study of high-velocity multiple impact on the structural behaviour of GFRP Cross-Ply laminates

Year: 2025

Type: article

Abstract: • Experimental study on behaviour of laminates under multiple high-velocity impact. • Comparison between single and multiple high-velocity impact is conducted. • Post-impact damage analysis was evaluated using non-destructive inspections. • Influence of the multiple impact phenomenon on response of GFRP was revealed. This study examines the experimental behaviour of composite structures subjected to high-velocity multiple impact, which is critical in applications where simultaneous impacts from multiple projectiles or debris may occur. This work also investigates the influence of the distance between projectiles on global variables, including the damaged area. Furthermore, a comparison is conducted between single and multiple high-velocity impact. The findings reveal that both the damaged area, the ballistic limit and the residual velocity of the projectiles are significantly affected by the simultaneous multiple impact phenomenon.
