Negative Poisson’s Ratio Honeycomb Structure and Its Applications in Structure Design of Morphing Aircraft

Abstract

Abstract:

This paper investigated a negative Poisson’s ratio flexible honeycomb structure.Then,a mechanics properties analysis theoretical model of flexible honeycomb was established. Finite element analysis results and test results were compared to analyse the mechanical properties. The results show that the negative Poisson’s honeycomb structure has substantial in-plane deformability and auxetics properties. Morphing wing with negative Poisson’s ratio flexible honeycomb structure has the potential of improving aircraft takeoff performance.

Key words: morphing wing, flexible honeycomb, in-plane deformation, mechanical property, negative Poisson’s ratio
