Abstract

Finite element simulations were performed to study the behaviour under impact loading of the sandwich composite made from woven glass fiber and polyvinylester resin composite facesheets and polypropylene hexagonal honeycomb core that can be used for safety important structures. The layered structure dynamical properties associated with energy absorption and dynamical stiffness was investigated.The obtained impact energy absorption and dynamical stiffness dependences of geometric parameters of the structure allow the assessment and the prediction of sandwich structures safety important parameters under impact loading and ensuring the efficient material expenditures.
