| Abstract: | On the basis of sandwich principle, the bending properties of different sandwich construction were studied. At the same time, based on the principle of simply supported beam and extended beam, the bending stiffness was analyzed. The results showed that the bending properties of sandwich construction with wood facings and paper honeycomb core is better than honeycomb fiberboard. The similar formula of bending stiffness was given about the wooding sandwich construction and the formula can forecast the stiffness of sandwich construction. The packaging material of sandwich construction with wood facings and a paper ho- neycomb core is a green packaging material of nice properties. The material will be widely used. |
