Ballistic Material for Brain Buckets
For the past two decades high-tenacity fibers such as S-glass, Aramid, and ultrahighmolecular- weight-polyethylene (UHMWPE) have been the materials of choice for making lightweight armor.
But today’s
soldiers, police officers, and other security
forces now have a 10% lighter helmet that far
exceeds Advanced Combat Helmet (ACH)
specs for impacts. The helmets also meet
all ballistic protection specs and greatly reduce
shock transference to the person they
protect, says Bob Miller, president of Diaphorm
Technologies LLC, Salem, N.H.
The company makes the composite combat
helmets from continuous-fiber-reinforced
thermoplastic composites (CFRTPCs). “In
standardized ACH tests,” says Miller, “the
helmet transferred one-third less impact
to the dummy head than any other helmet
tested.”
The new combat helmet is marketed
through Diaphorm’s subsidiary, Max Pro-
Police & Armor, and is listed as a BA3AMCIP-
Combat Ballistic Helmet. The helmet
shell construction resembles that of the
company’s NIJ Level IIIa tactical helmets
more than 10,000 Level IIIa’s have been
worn in Iraq and Afghanistan, and by U.S.
Police units.
Diaphorm’s proprietary quick-cycle
molding processes combine the inherently
tough, lower-density TPs with ballistically
rated continuous-fiber reinforcement.
This creates monolithic, hybrid, and hard-faced rigid CFRTPC helmet shells that are
10% lighter than other ACH-grade helmets.
Current production volumes average
100 units/day. “Demand has been so strong
for the new helmets that it tapped out our
current capacity,” says Miller. “So we doubled
capacity to 50,000 units/yr in May.
Diaphorm has also used the same basic
process to produce high-strength, lowweight
composite moldings in production
and prototype volumes for a variety of performance
automotive parts and recreational
gear including engine manifolds, solenoid
caps, industrial caps, and kayak structural
beams. The process is equally well suited for
either high or low volumes.
