Abstract The effects of impact site, impactor diameter and impactor shape on the low-velocity impact performance of the sandwich structure with curved-crease origami foldcore were investigated experimentally. The experimental results show that these three factors combined affect the low-velocity impact performance of composite sandwich structure with curved-crease origami foldcore. Besides, the low-velocity impact performance of composite sandwich structure with curved-crease origami foldcore, chevron origami foldcore and corrugation core are compared numerically. The numerical results show that the composite sandwich structure with curved-crease origami foldcore has better low-velocity impact performance.
Highlights A novel composite sandwich structure with curved-crease foldcore is fabricated. The influence of several impact factors on the low-velocity impact performance of the structure is investigated. A 3D progressive damage model of composite materials is established and good simulation results are obtained. Curved-crease foldcore has better low-velocity impact performance than chevron origami foldcore and corrugation core.
