Hexcel is
the largest weaver of Aramid and other high performance yarns in the
U.S. Hexcel has over 25 years of experience weaving high performance
yarns. Our ballistic protection customers manufacture civilian and
military body armor using Hexcel fabrics woven from Kevlar ®,
Spectra ®, Twaron ® and other high performance brand fibers. These
cutting-edge performance fabrics offer unmatched resistance to
bullets, fragments, cuts, stabs and abrasions, while offering
lightweight strength and comfort.
Civilian
police forces that are exposed to relatively high-mass/low-velocity
bullets will use a different fiber and different fabric weave
designs than military applications which encounter relatively low-mass/high-velocity
bullets and fragments. Hexcel’s years of experience and research in
this field have made us knowledgeable about effective weave designs
for the threats needed for protective clothing products. Lightweight,
durable and comfortable material is vital in this industry to make
sure that the users will not hesitate to wear soft body armor for
protection. The high strength of fabrics woven from Kevlar ®,
Spectra ® and Twaron ® brand fibers provides phenomenal ballistic
and blunt trauma protection which has saved thousands of lives.
Hexcel’s ballistic team is committed to finding the correct solution
to solve your ballistic fabric needs.
Many of
these high performance fabrics are now being used for industrial
protection. Since 9/11, we have seen an increased need for blast
resistance fabrics for government buildings, state buildings,
hospitals and industrial employee protection. Let us know how our
fabric can help you!
Kevlar ®
para-aramid fiber displays excellent dimensional stability over a
wide range of temperatures for prolonged periods. Even at
temperatures of 320° F (160° C) Kevlar ® shows essentially no
embrittlement or strength loss. Kevlar ® fiber also has excellent
dimensional stability with a slightly negative coefficient of
thermal expansion (-1.1 X 10-6/° F or -0.2 X 10-6/° C). Kevlar ®
fiber does not melt or support combustion but will start to
decompose at about 800° F (427° C).
Kevlar ®
29, 129 are tough yarns which are better suited for ballistic
protection and are used both in soft body armor applications such as
personal protection ballistic vests, and as robust reinforcements
for a variety of hard armor applications, racing helmets, ballistic
helmets, spall panels, ballistic blankets and electronic housing
protection.
Kevlar ® KM2, made in 400 denier, 600 denier and 850 denier, is a
high performance product variant specially designed for use in
Military ballistic applications. These yarns are used in both soft
and hard military products to defeat multiple threats.
Kevlar ® A-200 & LT are new yarns that are used in the development
of the lightest weight body armor products on the market today.
These new yarns are mainly used in the civilian police products to
provide comfortable, high level protection.
Kevlar ® K-159 was developed for correctional institutions as the
first stab resistant fabric. This new Kevlar ® fiber, which is 4
times thinner than typical ballistic yarns, is used for an
ultra-dense weave but still maintains a strength value that is five
times stronger than steel on an equal weight basis.
Kevlar ® XLT is one of the newest yarns developed for body armor.
This new yarn is available to licensed companies through Du Pont.
Spectra ®
900 is the original extended-chain ultra-high molecular weight
polyethylene fiber was introduced by Honeywell’s Spectra ®
Performance Materials in 1985. Common to all Spectra ® fibers, with
a high strength-to-weight ration, Spectra ® 900 is pound for pound 8
times stronger than steel. It is light enough to float, has superior
abrasion-resistance qualities, and is resistant to chemicals, water
and UV. Applications include safety products, such as cut-protective
gloves and abrasion resistant materials. Because of the hydrophobic
character, it is an excellent product for marine applications. See
our web page for fabric styles made with Spectra ® 900 yarns.
Spectra ® 1000, the second generation family of Spectra ® 1000
fibers was developed to provide higher strength, higher modulus and
improved creep properties as well as fibers with enhanced ballistic
performance in armor. As an extended chain, ultra-high molecular
weight polyethylene, Spectra ® 1000 fibers have a high strength-to-weight
ratio and is, pound for pound, 10 times stronger than steel. It is
light enough to float, has superior abrasion resistance and has
excellent resistance to chemicals, water and UV. Applications
include ballistic armor, cut-protective gloves and safety products.
See our web page for styles made with Spectra ® 1000 yarns.
Twaron ® is a high performance para-aramid fiber supplied by Teijin
Twaron ®. In the last 10 years of Twaron ® being in the marketplace,
many improvements in properties have been made. Developments of
finer filaments, uniquely combined with higher tensile properties,
resulted in the patented Twaron ® Microfilament and have led to the
newest types of Twaron ® yarns exceptionally well adapted to the
specific demands of hard and soft ballistic applications.
