Honeycomb is commonly manufactured from plastic, metal, or fibrous pulp, and is a type of material that is often used where impact protection is required.
It has a strong Specific Energy Absorption (SEA) in one direction, and none in the other two. MetaCORE has a strong SEA in all directions, which makes it isotropic.
With Crush Force Efficiency (CFE), honeycomb has a large peak stress, whereas MetaCORE was designed to eliminate this problem and has virtually no peak stress.
