With characteristics
including rot resistance, noncombustibility, high strength and
durability, fiberglass fabrics can meet critical and unusual design
needs for the military. Structural parts, armor reinforcement,
thermal and electrical insulation, and shipboard insulation are just
a few of the many military applications of fiberglass fabrics of
both "E" and "S-2" types.
Astroquartz II Fabrics
Astroquartz fabrics offer better solutions to high
heat, high strength problems. The aerospace industry relies on
Astroquartz quartz fiber products made from high purity (99.95%
SiO2) quartz crystals. An outstanding reinforcement for high
temperature and ablative space and missile applications, Astroquartz
products are recommended when low dielectric loss properties are
required, such as microwave transmission in radome and antenna
applications. Other applications include insulation for the space
shuttle, cable tray insulation for nuclear power plants and
laminated fabric for circuit boards. Conform formable Astroquartz
fabrics are recommended for use in preforms for resin transfer
molding (RTM), press molding and tooling applications.
Astroquartz III Fabrics
Astroquartz III fabrics, a new generation of quartz fabrics, are
a low-cost alternative to the nine micron fiber Astroquartz II
fabrics. Based on 14 micron filament yarns, Astroquartz III fabrics
are woven from high tensile strength, high purity (99.95%) fused
silica fiber yarns. Two fabric styles are available – 4503 and 4581.
Astroquartz III fabrics feature many of the successful attributes of
Astroquartz II fabrics. The epoxy laminates made from the new
Astroquartz III styles feature the same mechanical properties as in
Astroquartz II styles. Laminate test results are available upon
request. Astroquartz fabrics are known for their low dielectrics,
near zero coefficients of thermal expansion, high temperature
performance and excellent mechanical properties in composites.
With characteristics including rot resistance,
noncombustibility, high strength and durability, fiberglass fabrics

Many 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. 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. JPS’ 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. JPS’ ballistic team is committed to finding the correct solution to solve your ballistic fabric needs.
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® LT is a new yarn that’s used in the development of the lightest weight body armor products on the market today. This new yarn is 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 DuPont.
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® 1000, 2040 are high performance para-aramid fibers supplied by Teijin Aramid®. In the last 15 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.
S-2® Rovings are woven to produce a substrate with ballistic resistance properties for hard armor applications. The ballistic resistance is attained through the combination of the following variables: composite construction, resin system, resin content and fiber volume. S-2 ® Fabrics supplied to the markets have been approved in specific composite applications in MRAP programs.

Electrical
The excellent electrical
insulation and high temperature durability characteristics of glass
fabrics make them outstanding performers in the electrical
industry.
Almost all rotating equipment, transformers, switches,
wire and cable applications, as well as printed circuits, rely on
the high dielectric strength, dimensional stability and temperature
resistance of glass fabrics. In most cases, glass fabrics are used
in conjunction with other materials.
Closely woven lightweight fabrics are treated with
varnish, silicone rubber, Teflon* coating and Neoprene* coating for
use in bus bar winding, wire and cable wrap, etc. These same
fabrics, as well as open weave cloths, are used as substrates and
reinforcements for mica. Most of these combinations are slit into
tapes.
In the high pressure laminate and printed circuit
industry, glass fabrics are used to meet critical electrical,
temperature, corrosion resistance and dimensional stability
requirements. The glass fabric is impregnated with epoxy, polyester,
melamine, phenolic, polyimide and Teflon resins and is then
laminated under high pressure to form rigid boards for use as the
foundation for printed circuits.

Insulation
Woven
Excellent temperature and strength
properties, along with rot and mildew resistance, make fiberglass
fabrics indispensable in a broad range of marine, automotive and
commercial insulation applications. In many cases, fiberglass can
replace more costly insulation.
Non Woven
Insulation
The general transition from asbestos to glass
fibers has resulted in an increasingly wide range of applications
for Insulbatte/Tempmat – a mechanically (rather than organically)
bonded glass fiber insulating blanket. A 100% "E" fiberglass mat,
Insulbatte/Tempmat fabric is manufactured in web form and
mechanically needled together to form thicknesses of 1/4", 1/2" and
1". Long textile fibers have been accurately chopped to provide
maximum density, high insulation and strong physical properties in
temperatures up to 1200oF.
Insulbatte/Tempmat fabric is noncorrosive,
noncombustible, nonalkaline and chemically-stable. Its excellent
heat resistant, flexibility and low thermal conductivity make
Insulbatte/Tempmat products effective, low-cost replacements for
asbestos mats, millboard refractory paper and other similar
products.
Insulbatte/Tempmat products are being used to solve
increasingly complex applications in oil refineries, steam and gas
turbines, exhaust systems on diesel tugs, tankers. Coast Guard and
Navy vessels, and pleasure yachts. They are used to relieve stress
at welding points and on valve flange covers. In addition,
Insulbatte/Tempmat blankets act as insulators over automotive
thermactor switches, for floor pans over catalytic converters and in
luggage compartments.
In nuclear power plants, these blankets
reduce labor costs during removal for inspection and service, and
cut reinsulation costs associated with poor-fitting rigid block.

About Fiberglass
Properties
Fiberglass fabrics have many
unique and outstanding properties, which provide design
opportunities for the improvement of existing products and the
development of new products.
JPS technicians, design engineers and technical
representatives welcome the opportunity to combine their experience
and knowledge of these unique properties to provide the superior
products required by industry today.
Chemical
Resistance
Inorganic fiberglass textile fibers will not
rot, mildew or deteriorate. They resist most acids with the
exception of hydrofluoric acid and hot phosphoric acid.
Dimensional
Stability
The fiberglass yarns used in manufacturing glass
fabrics will not stretch or shrink as a result of changes in
atmospheric conditions. Nominal elongation at break is 3-4%. The
average linear thermal expansion coefficient of bulk E glass is 5.4
x 10-6 cm/cm/oC.
Good Thermal Properties
Fiberglass fabrics have a low coefficient of thermal
expansion and relatively high thermal conductivity. Glass fabrics
will dissipate heat more rapidly than asbestos or organic
fibers.
High Tensile Strength
Fiberglass yarn has a high strength-to-weight ratio.
Pound for pound, fiberglass yarn is twice as strong as steel wire.
The ability to design unidirectional or bidirectional strength into
a fabric adds considerably to end-use product flexibility.
High Thermal Endurance
Inorganic glass fibers cannot burn and are basically unaffected
by high baking and curing temperatures often encountered in
industrial processing. Fiberglass will retain approximately 50% of
its strength at 700oF and as much as 25% at 1000oF.
Low Moisture Absorption
Fiberglass yarn is made from noncellular fiber and,
therefore, experiences extremely low moisture absorption.
Outstanding Electrical Insulation
High dielectric strength and relatively low dielectric
constants, plus low water absorption and high temperature
resistance, make fiberglass fabrics outstanding for electrical
insulating purposes.
Product Flexibility
The
extremely fine filaments used in fiberglass yarns, the multitude of
yarn sizes and configurations that these yarns can have, as well as
weave types, and many special finishes, make fiberglass fabrics
available for a broad range of industrial end uses.
Low Cost
Fiberglass
fabrics do the job and compare favorably in cost with synthetic and
natural fiber fabrics.
Selection
The selection
of the proper fabric to meet the demands of your specific
application require the combined knowledge of industry designers and
engineers and JPS fiberglass design professionals.
Prior to selecting a fabric for any applications, we
recommend that you consult with a JPS technical or sales
representative.
About Quartz
Properties
Physical and Mechanical Properties
With a filament tensile strength of 870,000 PSI, (6.06Pa) Astroquartz® II quartz fiber has a higher strength-to-weight ratio than virtually all other high temperature materials.
Fibers are flexible and function well in applications subject to torsion and flexing. Astroquartz II fiber is transparent to ultraviolet radiation in the 2000A and upwards range. It does not form paramagnetic centers, nor does it capture neutrons in high-energy applications. Astroquartz II fiber is an excellent electrical insulator and retains these properties at high temperatures.
Chemical Properties
Astroquartz® II and III fibers (99.99% pure fused silica) are chemically stable. They are water-insoluble and nonhygroscopic. Halogens, common acids in either liquid or gaseous form, have no affect on Astroquartz II and III products with the exception of hydrofluoric and hot phosphoric acids. Astroquartz II and III products should not be used in environments where strong concentrations of alkalis are present.
Thermal Properties
Astroquartz® II and III quartz fiber can be used at temperatures much higher than either E glass or S® glass fiber, up to 1050 ° C. Above this temperature, slow devitrification or crystallization occurs with the loss of flexible mechanical properties. Repeatedly, varied temperatures and various impurities, especially alkalis, may promote devitrification at somewhat lower temperatures. Astroquartz II and III fiber softens at approximately 1300 ° C but never liquefies. Volatilization begins near 2000 ° C. Because of their very high melt viscosity; Astroquartz products are often used in ablative composites.
This fiber has a unique feature of nearly nil coefficient of thermal expansion in all directions (axial and radial). It is, therefore, an ideal reinforcement where dimensional stability under thermal cycling is critical, such as thermally controlled printed circuit boards for leadless ceramic chip carriers. This low coefficient factor also provides a great resistance to thermal shock, resulting in product suitable for applications involving abrupt thermal variations.
Electrical Properties
The dielectric constant and the loss tangent factor are the best to date among all mineral fibers, and these outstanding performance characteristics are maintained at high frequencies and high temperatures. For these reasons, this fiber is often considered the best choice for radomes and high-speed printed circuit boards.
Selection
There are five basic design variables to consider when choosing Astroquartz fabrics including thickness, weight, construction, yarn size and finish. The selection of the proper fabric to meet the demands of your specific application requires the combined knowledge of industry designers and JPS design professionals. Prior to selecting a fabric for any applications, we recommend that you consult with a JPS technical or sales representative.
