Abstract
In order to study the impact resistance and dynamic response of the composite honeycomb sandwich radome under high-speed bird impact, a simulation model of the bird impacting composite honeycomb sandwich radome with glass fiber reinforced composite (GFRP) panel and meta-aromatic polyphthalamide honeycomb (NOMEXR) core is established through the finite element simulation software LS-DYNA. The effects of thickness distribution of the upper and lower panels of the radome, and the layering angle of the upper panel on the impact resistance of the radome are studied. The research results show that the increase in the thickness distribution of the upper panel is a positive gain for impact resistance of the radome. Inserting some other angled layers in the orthogonal layer can improve the impact resistance of the honeycomb sandwich structure.
