Polypropylene honeycomb is mainly used as core in composite panels, as reinforcement and as means to lighten structures. The honeycomb is closed on its both sides with a thermo-welded tissue. In case of bending the strain is transferred by the honeycomb core. That is why the strain is shared out in shear and compression over laminates.
