Items

  1. Filament or Monofilament is the smallest increment of fiber, usually several µm in diameter.
  2. Strand is a bundle of filaments (typically over 200) arranged approximately parallel.
  3. Roving is a bundle (typically 12-120) of approximately parallel strands.
  4. Yarn is a bundle of twisted strands.
  5. Tow is a bundle of filaments, usually approximately parallel.
  6. Tape is a material constructed of interlaced or unidirectional filaments, strands, rovings, tows, or yarns, etc., usually preimpregnated with resin.
  7. Specific modulus is the Young's modulus in N/m 2 divided by the specific weight in N/m 3, measured at a temperature of (296 ±2) K ((23 ±2) °C) and a relative humidity of 50 ±5 percent.
  8. Specific tensile strength is the ultimate tensile strength in N/m 2 divided by specific weight in N/m 3, measured at a temperature of (296 ±2) K ((23 ±2) °C) and a relative humidity of 50 ±5 percent.
  9. Items: a. Carbon or aramid “fibrous or filamentary materials” having a “specific modulus” of 12.7 × 10 6 m or greater or a “specific tensile strength” of 235 × 10 3 m or greater except Aramid “fibrous or filamentary materials” having 0.25 percent or more by weight of an ester based fiber surface modifier;
  10. b. Glass “fibrous or filamentary materials” having a “specific modulus” of 3.18 × 10 6 m or greater and a “specific tensile strength” of 76.2 × 10 3 m or greater; or
  11. c. Thermoset resin impregnated continuous “yarns”, “rovings”, “tows” or “tapes” with a width no greater than 15 mm (prepregs), made from carbon or glass “fibrous or filamentary materials” controlled by 1C210.a or .b.
