449 S-2 Glass® Roving
High-Strength Solutions for Your Toughest
Reinforcement Challenges

AGY’s S-2 Glass® high-strength bers
are specically designed to meet your
most demanding performance
processing and cost requirements.
AGY’s global network of people and
facilities are ready to help you develop
innovative solutions to your most
difcult reinforcement challenges.
Product Application
449 S-2 Glass roving is designed to
be used in aerospace, defense and
recreation applications such as:
• Helicopter blades • Golf shafts
• Pressure vessels • Aircraft ooring
• Aircraft fuel tanks
Product Solutions
S-2 Glass bers offer a unique
combination of properties: strength,
impact resistance, stiffness, radar
transparency and temperature and
fatigue resistance. Compared with
other reinforcing materials, S-2 Glass
bers weigh less than conventional
glass ber and deliver better cost
performance than aramid and carbon
bers. In addition, they meet the
requirements of MIL-R-60346 Type IV,
Class 1 specications.

Features

Benets

S-2 Glass ber offers signicantly
more strength than conventional glass
ber: 85% more tensile strength in
resin impregnated strands

Consistent high performance for
reliable and durable nished parts

Better ber toughness, modulus of
resilience and impact deformation
than conventional glass ber

Improved impact capabilities to
nished parts and higher
composites durability and
damaged tolerance

Product Description
449 S-2 Glass roving consists of
numerous G-lament (9 micron)
continuous glass strands, gathered
without mechanical twist and treated
with an amino-silane, epoxycompatible sizing.

Softening point: 1056°C (1932°F)
Annealing point: 816°C (1500°F)
Strain point: 766°C (1410°F)

Greater ber tensile strength and
stability at elevated temperatures
in thermoset and thermoplastic
applications

Enhanced stiffness

Resin Compatibility
• Epoxy (amine-cured)
• Urethane (selected)

Delivers 25% more linear-elastic
stiffness than conventional glass
ber

Excellent tolerance to damage
accumulation

The ability of composite parts to
withstand high levels of tension
and exural fatigue without
catastrophic failure

Processes
• Weaving
• Hand Lay-up
• Uni-Directional Pre-Impregnation
• Filament Winding
• Contact Molding
• Compression Molding

S-2 Glass bers deliver 20% reduction
Radar transparency
in dielectric constant over E-Glass bers
Long shelf life, good machinability and
excellent durability

Consistent performance and
reliability

Quick wet-out (penetration of resin into
the strand)

Faster, more efcient processing
