Steel-polymer Protective Armor Plate
Project number:
21061
Sponsor:
Spartan Armor Systems
Academic year:
2020-2021
Project Goal: Design and fabricate a steel-polyethylene composite armor plate that balances performance, weight, cost, durability and comfort.
Spartan Armor Systems wanted a level III body armor that would stand out among the competition in a growing market. Traditional steel armor is cost-effective and simple to manufacture, but its heavy weight can cause user fatigue and other prolonged physical problems.
The hybrid armor plate weighs less than five pounds and measures just over 1/2-inch thick. The HAP is the first composite plate to combine ballistic-rated steel and polyethylene to create a stronger and lighter body armor.
HAP was tested against the performance standards established by the National Institute of Justice for level III protection: NIJ-Standard-0101.06. Level III offers protection against basic rifle threats and is certified to stop a 7.62x51mm M80 Ball NATO round, which has a mass of 9.6g and a velocity of 847 meters per second. The test determined the optimal configuration of the HAP, balancing spall (fragmentation) mitigation and impact resistance.
