具有二维（2D）棱柱形或三维（3D）晶格桁架芯的超轻夹层结构，例如蜂窝、折叠板（波纹）和金字塔形桁架，已知具有吸引人的机械刚度/强度和抗冲击性。这些性能可以显着改善进一步通过插入不同的材料到晶格的间隙，以构建混合晶格芯三明治，总结在这个迷你审查。讨论了三种不同类型的用于夹层结构的混合网格芯体，包括填充陶瓷或混凝土的网格芯体，用于上级抗穿透性，填充金属或聚合物泡沫的网格芯体，用于同时增强承载和能量吸收，以及用于同时承载、能量吸收和宽带低频吸声的金属蜂窝-蜂窝芯体。探讨了相应的增强机制。(C)2016爱思唯尔有限公司版权所有
Ultralight sandwich structures with either two-dimensional (2D) prismatic or three-dimensional (3D) lattice truss cores, such as honeycombs, folded panels (corrugations) and pyramidal trusses, are known to possess attractive mechanical stiffness/strength and impact resistance. These properties can be significantly improved further by inserting different materials into the interstices of the lattices to construct hybrid lattice-cored sandwiches, as summarized in this mini-review. Three different types of hybrid lattice-core for sandwich constructions are discussed, including ceramic-or concrete-filled lattice cores for superior penetration resistance, metallic or polymeric foam-filled lattice cores for simultaneous enhancement in load-bearing and energy absorption, and metallic honeycomb-corrugation cores for simultaneous load-bearing, energy absorption and broadband low-frequency sound absorption. Corresponding enhancement mechanisms are explored. (C) 2016 Elsevier Ltd. All rights reserved.
