The FIBER lab aims to develop novel fibers and fabrics that integrate new capabilities into structures and composites. 


  • Compounding of new reinforcements and additives into polymers for extrusion.
  • Extrusion of polymers into filaments or fiber bundles.
    Electrospinning of new polymer fibers or mat.
  • Weaving of prototype fabrics in 2D or 3D fiber architectures.
  • Knitting of prototype and low-rate production fabrics and garments up to 1.27 meters (50 inches) wide.
  • Woven and knitted fabric design.
  • Characterization of fabrics and fibers with regard to
  • Digital microscopy to 10-1000x
  • 1D fiber tensile tests
  • 1D fabric tensile tests
  • Surface energy
  • EMI Shielding effectiveness 30Mhz-10GHz
