  • 1965, Dupont

  • Stehanie Kowlek & Herbert Blades

  • Aromatic polyamide

  • Symmetrical radial orientation


Properties

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
