  • Patent number: 6403504
    Abstract: The instant invention involves a process used in preparing fibrous tows which may be formed into polymeric plastic composites. The process involves the steps of (a) forming a carbon fiber tow; (b) forming a thermoplastic polymeric fiber tow; (c) intermixing the two tows; and (d) withdrawing the intermixed tow for further use.
    Type: Grant
    Filed: December 2, 1999
    Date of Patent: June 11, 2002
    Assignee: Cytec Technology Corp.
    Inventors: Paul E. McMahon, Tai-Shung Chung, Lincoln Ying

  • Patent number: 4874563
    Abstract: A continuous, substantially uniform tow useful in forming composite molded articles is prepared by forming a continuous tow of continuous carbon fibers, forming a continuous tow of thermoplastic polymer fibers to a selected width, uniformly and continuously spreading the carbon fiber two to a width that is essentially the same as the selected width for the thermoplastic polymer fiber tow, intermixing the tows intimately, uniformly and continuously, in a relatively tension-free state, and continuosuly withdrawing the intermixed tow.
    Type: Grant
    Filed: December 5, 1986
    Date of Patent: October 17, 1989
    Assignee: BASF Structural Materials Inc.

  • Patent number: 4871491
    Abstract: A composite article is prepared by forming a continuous tow of continuous carbon fibers, forming a continuous tow of thermoplastic polymer fibers, uniformly and continuously spreading the thermoplastic polymer fibers to a selected width, uniformly and continuously spreading the carbon fiber tow to a width that is essentially the same as the selected width for the thermoplastic polymer fiber tow, intermixing the tows intimately, uniformly and continuously, in a relatively tension-free state, continuously withdrawing the intermixed tow and applying the tow to a mold and heating the tow.

    Assignee: M&T Chemicals Inc.
    Inventors: Robert Edelman, Lincoln Ying
  • Patent number: 4818318
    Abstract: The instant invention involves a process used in preparing fibrous tows which may be formed into polymeric plastic composites. The process involves the steps of (a) forming a tow of strong filamentary materials; (b) forming a thermoplastic polymeric fiber; (c) intermixing the two tows; and (d) withdrawing the intermixed tow for further use.
