Abstract

In this study two different types of flexible pads with novel cellular structures, i.e. honeycomb and re-entrant honeycomb were designed and additively manufactured by a SLA 3D printer using two different types of flexible photo-curable resin materials. The low-velocity impact resistance capacity and compressive properties of both structures were experimentally investigated. The dynamic impact test results showed that the one with re-entrant honeycomb cellular structure experienced reduced peak impact force of 2.73 N and 2.64 N for both resin materials. Moreover, the predicted response of FE model was highly correlated to experimental results. The results of compression test exhibited excellent energy absorption under wide displacement range for both structures. It is believed both pads with uniquely designed cellular structures have the potential to be used for protective materials against low-velocity impact.
