3. What is Kevlar® fiber
• Kevlar® a Para amide fibre is trade name from
first commercialised in 1972.
• High Tensile Strength at Low Weight
• Low Elongation to Break
• High Modulus (Structural Rigidity)
• High Chemical Resistance
• Excellent Dimensional Stability
• High Cut Resistance
• Flame Resistant, Self-Extinguishing

5. Introduction to new fibers
New series of fibres
(Advanced Performance )
o 15% more stronger.
o Reduce backface deformations by
approximately 15%.
6. o Highly fibrillated, short (0.5–1mm) fibers
o Yellow colour
o Useful temperature range (-200 to +350°)
7. Honeycomb core technology
• Composites made with Kevlar®
• Mainly used for aerospace and marine
application
• Provides lightweight strength,
stiffness, toughness, corrosion resistance
8. In Aerospace
• Kevlar® helped Airbus‘ which is concept of
the world's largest aircraft to become a
reality," said Jim Weigand
• Mainly used for weight reduction & increase
fuel efficiency.
• It is found flooring to interior walls to wing
flap to engines
9. In Marine
• Light weight providing strength, stiffness and toughness
• Versatile options for hulls, superstructures
• and furniture bulkheads
• Ideal for economies of fuel and/or increased
payloads
High impact and fatigue resistance
10. Liquid body armour
• Use of shear stress fluid
Behaves like liquid in normal condition
but solidifies in millisecond when strikes.
Silicon particles suspended in
polyethylene glycol.
Enclosed between different Kevlar®
sheets
11. Light weight Helmet
• Made with Kevlar® XP™
• Reduction in 15% back-face deformation
• Higher protection per weight than existing
aramid-phenolic solutions: shell weight
reduced by 20-25%
13. Advanced materials for the oil & gas
industry
• DuPont technology has set new standards in
extraction, pipeline performance, extreme weather
operations, and workforce protection.
• Thermoplastic umbilicals
• FLEXIBLE LINES
• INNOVATIVE SAFETY
• REINFORCED THERMOPLASTIC PIPES
14. Automotive industry
• Tyres
Superb puncture, abrasion and tear resistance
• Belts
• The high modulus and abrasion resistance of Kevlar® yarn help belts
retain their original shape and tension over the millions of revolutions
they go through over the lifespan of a vehicle
• Brake pads
The enhanced thermal stability and inherent abrasion resistance of
brake pads reinforced with Kevlar® pulp helps allow them to last long
and stop the vehicle safely and quietly.
• Gaskets
• Chemical stability and thermal stability help make gaskets reinforced
with Kevlar® pulp strong and durable
15. Optical cables
• Improved coverage of the optic fibre
• Provide crush resistance and
cushion protection for the optic fibre.
• Tight buffered fibre separated from
the cable jacket to prevent sticking
• Load-bearing capacity
16. Heat Resistant Gloves
• Made from Kevlar ® AP
• Cut resistance
• Light weight
• High strength
