Development of a Cubic Core Lightweight Panel Using Origami-Kirigami Engineering

Honeycomb core panels are commonly used in industry as lightweight structures. However, because the bond between face plate and regular hexagonal is weak, there strength problems, such heat shear loads. In this study, a new cubic panel was developed an alternative to honeycomb panel. Unlike conventional panels, cores can be processed from single flat by punching bending. Through square contact area core, double-bond integral structure assembled using glue rebates. The had higher bending stiffness bonding than A three-point test performed on relationship load deformation of determined. curved part easily cutting out material one side accordance with part. design formula for derived curvature radius angle actual structure. molding system investigated parallel movement characteristics four-bar link mechanism future mass production. An important factor practical use obtained deriving relational expression plastic displacement.
