近日,美国麻省理工学院的研究人员开发出一种利用微小型结构复合材料组装成大结构的新方法。这些轻巧的小型结构可以像堆积木一样环环相扣,最后形成像“锁子甲”一样的轻量级结构材料。新设计方法结合了纤维复合材料、多孔材料和添加制造技术(如3D打印技术)三种领域的研究,形成的这种新材料能 Recently, researchers at the Massachusetts Institute of Technology in the United States have developed a new method of assembling large structures using microstructured composite materials. These lightweight, compact structures interlock around like a pile of wood and finally form lightweight structural materials like the “locker”. The new design methodology combines three areas of fiber composites, porous materials, and additive manufacturing technologies such as 3D printing to create new materials that can
