Role of material directionality on the mechanical response of Miura-Ori composite structures

This paper aims to understand the role of directional material properties on mechanical responses origami structures. We consider Miura-Ori structures our target model due their collapsibility and negative Poisson's ratio (NPR) effects, which are widely used in shock absorbers, disaster shelters, aerospace applications, etc. Traditional made isotropic materials (Aluminum, Acrylic), whose like stiffness NPR well understood. However, how these affected by materials, Carbon Fiber Reinforced Polymer (CFRP) composites, lacks in-depth understanding. To that end, we study fiber directions arrangements CFRP composites Miura-Ori's geometric parameters control such Through finite element analysis, show can achieve higher values than those an Aluminum. Then through regression establish relationship between different corresponding responses, is further utilized discover structure's optimal shape. also shear modulus a dominant parameter controls mentioned above among individual composite within structure. demonstrate optimize structure finding result combined stiffest most compressible anticipate research be starting point for designing optimizing more sophisticated with incorporated.
