Abstract
The purpose of this paper is the development of lightweight high bending strength panel. The bending strength properties of honeycomb cellular structure panel were examined. At the beginning, the honeycomb cellular shapes and sizes were examined, we selected a regular hexagonal cell which was thought to be the most useful for getting lightweight, high bending strength panels. Next, regular hexagonal honeycomb cellular panels were made mainly from old corrugated containers (OCC) or rock wool (RW). The specific bending strengths (bending strength / panel density) of these panels were found to be more than 20N/mm2. The properties of these panels were superior to standardized fibreboards with regards to bending strength. It was confirmed that the honeycomb cellular structure was effective for getting a lightweight high bending strength panel.
