U.S. Army Research Laboratory-led Army ManTech program has achieved a
breakthrough in the ability to process thermoplastic-based composites for
use in the helmets of soldiers. The new material grades have produced
several types of head protection, each of which saves at least
one-quarter the weight and up to 35% higher tolerance from fragmenting

it was deemed best suited to operate within the confines of an
environment that was deigned for humans in the first place.
