This paper aims to understand the role of directional material properties onthe mechanical responses of origami structures. We consider the Miura-Oristructures our target model due to their collapsibility and negative Poisson'sratio (NPR) effects, which are widely used in shock absorbers, disastershelters, aerospace applications, etc. Traditional Miura-Ori structures aremade of isotropic materials (Aluminum, Acrylic), whose mechanical propertieslike stiffness and NPR are well understood. However, how these responses areaffected by directional materials, like Carbon Fiber Reinforced Polymer (CFRP)composites, lacks in-depth understanding. To that end, we study how fiberdirections and arrangements in CFRP composites and Miura-Ori's geometricparameters control the stiffness and NPR of such structures. Through finiteelement analysis, we show that Miura-Ori structures made of CFRP composites canachieve higher stiffness and Poisson's ratio values than those made of anisotropic material like Aluminum. Then through regression analysis, weestablish the relationship between different geometric parameters and thecorresponding mechanical responses, which is further utilized to discover theMiura-Ori structure's optimal shape. We also show that the shear modulus is adominant parameter that controls the mechanical responses mentioned above amongthe individual composite material properties within the Miura-Ori structure. Wedemonstrate that we can optimize the Miura-Ori structure by finding geometricand material parameters that result in combined stiffest and most compressiblestructures. We anticipate our research to be a starting point for designing andoptimizing more sophisticated origami structures with composite materialsincorporated.
