The results show that ,the compression deformation is nonlinear characteristics, and compression deformation process experience sticky elasticity and plasticity, plasticity of collapse and close-grained four phases. And analysis of the various stages of variation characteristics. Then Make fitting function . Determination analysis the environment relative humidity to honeycomb paperboard compression of hexagon properties influnce. Found in RH50% ~90% range, the honeycomb core paper with compression strength decreased the increase of relative humidity ,And it have the markedly directional, the thickness of the honeycomb paperboard larger by humidity affect the more obvious.
