Abstract

A plated fiber that is obtained by applying a metal plating onto a fiber having an elongation percentage which is more than or equal to 1% and less than or equal to 10%. An elongation percentage of the metal plating is higher than the elongation percentage of the fiber. A carbon fiber wherein the surface oxygen amount as a value obtained by dividing an O 1S peak intensity measured by X-ray photoelectron spectroscopy by a C 1S peak intensity measured by the spectroscopy is more than or equal to 0.097 and less than or equal to 0.138.

First claim

What is claimed is:

1 . A plated fiber obtained by applying a metal plating onto a fiber having an elongation percentage which is more than or equal to 1% and less than or equal to 10%, wherein
an elongation percentage of the metal plating is higher than the elongation percentage of the fiber.

2 . The plated fiber according to claim 1 , wherein the elongation percentage of the metal plating is more than or equal to 8.5% and less than or equal to 24.1%.

3 . The plated fiber according to claim 1 , wherein a gradient of a tensile load relative to the elongation percentage of the fiber is greater than a gradient of a tensile load at the time of reaching a maximum elongation percentage in an elastic region of a metal constituting the metal plating, relative to the maximum elongation percentage.

4 . A wire harness comprising an electric wire using the plated fiber according to claim 1 as a conductor part, the conductor part being coated with an insulator.

5 . The plated fiber according to claim 1 , wherein a cross-sectional area of the metal plating is same as a cross-sectional area of the fiber.

6 . A method for producing the plated fiber according to claim 1 , comprising:
applying a heat treatment to the metal plating.

7 . A carbon fiber, wherein a surface oxygen amount which is a value obtained by dividing an O 1S peak intensity measured by X-ray photoelectron spectroscopy by a C 1S peak intensity measured by the spectroscopy is more than or equal to 0.097 and less than or equal to 0.138.

8 . A wire harness comprising an electric wire using, as a conductor part, a plated fiber obtained by applying a metal plating onto the carbon fiber according to claim 7 , the conductor part being coated with an insulator.

9 . A plating method of applying a metal plating onto a carbon fiber, the plating method comprising:
a first step of charging a carbon fiber into a processing tank into which an organic metal complex is not charged, a second step of supplying carbon dioxide adjusted to a supercritical state to the processing tank into which a carbon fiber is charged in the first step, a third step of taking out the carbon fiber from the processing tank after a predetermined time is passed since carbon dioxide adjusted to a supercritical state is supplied in the second step, and a fourth step of applying by electroplating a metal plating onto the carbon fiber taken out in the third step.

10 . The plating method as claimed in claim 9 , wherein
in the second step, the carbon dioxide is adjusted to a pressure of 15 MPa and a temperature which is more than or equal to 100° C. and less than or equal to 200° C., and caused to enter the supercritical state, and the predetermined time is 60 minutes.
