Based on experiments used to evaluate the in-plane and out-of-plane mechanical properties of Nomex honeycomb, the influences of different cell geometries and honeycomb densities on the mechanical properties of honeycombs were investigated. The content of each component of honeycomb was analysed by disassembly. Furthermore, by introducing the wall thickness ratio and a correction function, a theoretical prediction model of out-of-plane mechanical properties was constructed. As for the prediction of in-plane mechanical properties, a three-layer structural finite element model of the cell walls was established through the use of a user-defined integration method.
