  1. KEVLAR What is it Properties Uses

  2. What is it • 1965, Dupont • Stehanie Kowlek & Herbert Blades • Aromatic polyamide • Symmetrical radial orientation

  3. Properties Available grades: Kevlar 29, Kevlar 49, and Kevlar 149 • Dadvantages • High Tensile Strength at Low Weight • 5X stronger than stronger than steel (equil weight basis) • Low Elongation to Break High Modulus • (Structural Rigidity) • Low Electrical Conductivity • High Chemical Resistance • Low Thermal Shrinkage • High Toughness (Work-To-Break) • Excellent Dimensional Stability • High Cut Resistance • Flame Resistant, Self-Extinguishing • Impact resistant • Disadvantages • Fibers absorb moisture • Poor compressive properties • Difficult to cut

  4. Uses • Performance Apparel • Adhesives and Sealants • Belts and Hoses • CompositesFiber-Optic and ElectroMechanical Cables • Friction Products and GasketsProtective ApparelTires

  5. Uses • Ropes and Cables

  6. Uses • Ballistics& • Defense Protection Level: Colors:  Sizes:
