Honeycomb
Perhaps the lightest weight core option, honeycomb materials are used in aerospace, military, high-performance marine, motorsports and other high performance applications.
Honeycomb cores are manufactured from a wide variety of materials including, fire-resistant Nomex®, aluminum, and thermoplastics, most commonly, polypropylene. These cores are available in a range of cell sizes and cell wall thickness to provide a wide scope of mechanical and thermal properties that perform in demanding and critical applications.
