“…Engineers and scientists have developed several applications of PCMs. Choi, et al [3,4,5,6] created a unit cell model with a truss and developed a complex structure and unit cell models such as corrugated wire mesh laminate and pinwheel trusses. The development of a new unit cell model is the most important aspect for building a sandwich core structure.…”

This study aims to provide critical information regarding the development of ultralight materials with tailored properties using a triangular unit cell model. Three different types of triangular unit cells (or triangular prism unit cells, e.g. OST, OTT, and CTT) were studied via finite element analysis to calculate and compare their relative density, stiffness, and strength. The relative stiffness and strength were extracted under a compression load. The ideal solutions were calculated using commercial finite element analysis software and then compared to the ideal Gibson-Ashby solution. The relative Young's modulus and the relative yield strength for the three different unit cell models are shown to differ from the ideal solution of the Gibson-Ashby theory. In conclusion, the effective stiffness of the OTT and CTT is higher than that of the Gibson-Ashby model. When the relative density is more than 0.1, the OTT and CTT have higher yield strength. OTT and CTT have a higher plastic strength when the relative density is more than 0.03-0.05. For aerospace or automobile use, further study is needed to find the optimum truss and aperture sizes and shape of the unit model.

“…One of the advantages of sandwich structures is that they can have a relatively high fraction of open space, hence a much lower density as compared to the parent material. In nature, cellular materials have evolved to make biological parts more structurally efficient by eliminating unstressed material and providing pathways for the growth of other organic materials [3]. The corrugated core sandwich panel is a progressive evolution of lattice truss structures in which the metal trusses are replaced with metallic wires, which facilitates fabrication due to the continuous nature of the wire-mesh employed as raw material.…”

“…Typically, alternate layers of the corrugated core sandwich panels are arranged orthogonally so that the high stiffness provided by the corrugation is available in both directions. Unlike metallic foam, which also has potential for similar application, the CWML offers the advantage of controllable rigidity and strength [3]. The material of the wire mesh, wire diameter, opening width, and corrugation parameters such as the corrugation height and the base angle can be altered to provide a wide range of strength to the laminate structure [5].…”

Aluminium sandwich construction has been recognized as of promising concept for structural design of light weight transportation systems such as aircraft high speed trains and fast ships. The aim of the present study is to investigate strength characteristics of aluminium sandwich panels with aluminium corrugated core experimentally. A series of crushing and bending test is carried out on corrugated core sandwich panel. The comparison of results is done based on the parameters viz. no of layers and patterns of perforated sheets. The structural failure characteristics of corrugated core sandwich panels are discussed. The test data developed are documented.
