Research on low-velocity impact resistance and damage characteristics of M-type GFRP foldcore sandwich structure

Vol. 23, no. 3

art. no. e193, 2023

The M-type GFRP foldcore was prepared by thermal pressing method and was bonded with the panel to obtain the complete foldcore sandwich structure. The influence of impact energy and impact position on the damage mode and impact dynamic response under the low-velocity impact of GFRP M-type foldcore sandwich structure is studied through experiment and numerical simulation. The results show that the impact position has a significant influence on the damage mode and impact resistance of the foldcore sandwich structure, mainly fracture damage at Base-impact while mainly tensile damage at Node-impact. The impact resistance of Node-impact is better than the Base-impact. The numerical simulation model can also predict the damage mode and the impact dynamic response well.
