Ceradyne developed a solution based on Cellular Materials International Ines (CMI) MicroTruss, an aluminium-based periodic cellular material which has a density of 58 kg/m2 compared to the 112 kg/m2 of an equivalent monolithic metal solution. The solution features a "V" angle of only 5°, sufficient to deflect the blast while limiting ground clearance reduction, and has a weight of 300 kg. MicroTruss ensures an absorption of up to 30% of the blast energy, which not only limits the impulse in the crew cell, but also mitigates the vertical lift of the vehicle.
