Abstract

<p>The honeycomb core with hexagonal cross section has now the maximum bending stiffness per weight which has made the honeycomb a trillion yen industry. But the cubic core with rectangle cross section here proposed has higher flexural rigidity per weight than the honeycomb core theoretically. This is confirmed also by FEM simulation. In the case of honeycomb core, bonding area between core material and upper or lower face plate is so small that it's hard to apply to the structures which receive vibration load and shear load over a long period of time. On the other hand, in the case of cubic core, it has so much larger bonding area between core material and upper or lower face plate that it eliminates the above drawbacks of the honeycomb. Cubic core molding process only consists of making a hole from one sheet and bending even for the structure with a curved part of which molding cost is much cheaper than honeycomb which is molded by extension type or corrugated type both of which process has a gluing process.</p>
