  • Patent number: 11286583
    Abstract: A carbon fiber bundle is characterized in that a ratio (n/N) of a number n of pairs wherein a flaw of 50 nm in size or more is present on at least one of the fracture surfaces forming the pair to a total number N of pairs of fiber fracture surfaces selected at random after performing a single fiber tensile test for a gauge length of 10 mm is 35% or less, and in that a single-fiber diameter d is 4.3 ?m or more.
    Type: Grant
    Filed: June 28, 2017
    Date of Patent: March 29, 2022
    Assignee: Toray Industries, Inc.

  • Patent number: 10738171
    Abstract: Provided is a sizing-coated carbon fiber bundle that exhibits good spreadability in a step for spreading sizing-coated carbon fibers even in the case in which said carbon fibers exhibit a high adhesiveness with respect to a thermoplastic resin. Provided is a sizing-coated carbon fiber bundle that contains, as sizing components, at least a compound (A) containing an amino group or an amide group.
    Type: Grant

  • Publication number: 20190194829
    Abstract: A coagulated yarn, which is used to manufacture carbon fiber, is a coagulated yarn the surface hole diameter of which is 30 nm or less and the degree of swelling is less than 100% or a coagulated yarn the surface hole diameter of which is 30 nm or less and the inner hole diameter is 30 nm or less. The carbon fiber precursor fiber and the carbon fiber are obtained using such a coagulated yarn.
