Fiber Characteristics

  • E-glass: A low alkali borosilicate glass with good electrical and mechanical properties and chemical resistance. The most widely used fiber for reinforcing plastics.
  • S-Glass: A stiffer and stronger version of E-glass, used in polymer matrix composites requiring improved mechanical properties.
  • PAN-Based Carbon Fibers: Made from polyacrylonitrile (PAN). These are high-strength, high-stiffness materials used in advanced constructions like military aircraft.
  • Alumina/Silica (e.g., Saffil): Produced as a fiber and developed for thermal insulation at higher temperatures.
  • *Kevlar 29: Used in industrial applications such as cables, asbestos replacement, brake linings, and body armor.
  • *Kevlar 49: Considered to have the greatest tensile strength of all aramids, used for plastic reinforcement in applications like boat hulls, airplanes, and bikes.
