  • CARBON FIBER
    Publication number: 20140343218
    Abstract: A method of making a carbon fiber structure including a carbon fiber is coated with a sizing at an amount X between 0.05 and 0.30 weight %. The sizing is formed of a heat resistant polymer or a precursor of the heat resistant polymer. The amount X of the sizing is expressed with a following formula: X = w 0 - w 1 w 0 × 100 where W0 is a weight of the carbon fiber with the sizing, and W1 is a weight of the carbon fiber without the sizing.
    Type: Application
    Filed: January 23, 2014
    Publication date: November 20, 2014
    Applicant: TORAY CARBON FIBERS AMERICA, INC.
    Inventors: Makoto Kibayashi, Satoshi Seike, Lawrence A. Pranger
  • CARBON FIBER
    Publication number: 20130253096
    Abstract: A carbon fiber is coated with a sizing at an amount X between 0.05 and 0.30 weight %. The sizing is formed of a heat resistant polymer or a precursor of the heat resistant polymer. The amount X of the sizing is expressed with a following formula: X = w 0 - w 2 w 0 × 100 where W0 is a weight of the carbon fiber with the sizing, and W1 is a weight of the carbon fiber without the sizing.

  • THERMOPLASTIC RESIN IMPREGNATED TAPE
    Publication number: 20130143025
    Abstract: A thermoplastic resin impregnated tape is made of a carbon fiber, which is coated with a sizing at an amount X between 0.05 and 0.30 weight %. The sizing is formed of a heat resistant polymer or a precursor of the heat resistant polymer. The amount X of the sizing is expressed with a following formula: X = W 0 - W 1 W 0 × 100 where W0 is the weight of the carbon fiber with the sizing, and W1 is the weight of the carbon fiber without the sizing.

  • CARBON FIBER
    Publication number: 20120123053
    Abstract: A carbon fiber is coated with a sizing at an amount X between 0.1 and 0.3 wt %. The sizing is formed of a heat resistant polymer or a precursor of the heat resistant polymer. The amount X of the sizing is expressed with a following formula: X = w 0 - w 1 w 0 × 100 where W0 is a weight of the carbon fiber with the sizing, and W1 is a weight of the carbon fiber without the sizing.
