The final layer is the same as the first a CFRP to act as the skull bone. Bio-inspired honeycomb sandwich beams when compared to conventional beams reduced area damage by 50-80% and carried 2.7-20 times lower stresses in the bottom layer while having an impact resistance efficiency 1.65-16.22 times higher.
