Abstract

A new ultralow density material (ULDM) named Shellular was recently introduced. Shellular has a periodic cellular structure with smooth-curved shells. The template for the first Shellular was fabricated using lithography and its shape was similar to the P-surface, a type of triply periodic minimal surface (TPMS). In this paper, a new fabrication method of Shellular with D-surface, named W-Shellular, is described. W-Shellular is fabricated based on weaving of polymer wires. The compressive properties are evaluated by experiments and analysis in comparison with the previous ULDMs.

최근 Shellular라는 새로운 극저밀도 재료가 소개되었다. Shellular는 주기적 구조를 가지면서도 한장의 부드러운 곡면의 쉘로 구성되어 있다. 최초의 Shellular는 리쏘그래피를 이용하여 제조되며 3주기최소곡면의 일종인 P-곡면과 유사한 형태를 갖는다. 본 연구에서는 와이어 직조에 기반하여 D-곡면과 유사한 Shellular를 제작하는 새로운 방법을 제시한다. 실험과 유한요소해석을 통하여 압축하중 하의 재료물성을 평가하고 종래의 극저밀도 재료와 비교하였다.
