Abstract

A plated plated fiber-reinforced member includes: a fiber-reinforced member formed of a composite fiber material in which multiple reinforcing fibers dispersed in a resin, some of the multiple reinforcing fibers being allowed so that portions thereof protruding from a surface of the resin; and an electroless-plated layer formed on the fiber-reinforced member to cover the surface of the resin and the portions of the reinforcing fibers protruded from the surface of the resin.

First claim

The invention claimed is:

1. A plating method for a fiber-reinforced member comprising:
an etching step of etching a surface of the fiber-reinforced member formed of a composite fiber material in which multiple reinforcing fibers are dispersed in a resin using an etching solution to selectively-dissolve the resin, thereby exposing portions of some of the multiple reinforcing fibers from a surface of the resin;
a vibration step of vibrating the fiber-reinforced member, thereby removing the reinforcing fibers fully exposed from the etched resin from the resin;
a catalyst adsorption step of adsorbing catalysts on the surface of the resin on which multiple recessed portions are formed and the portions of some of the reinforcing fibers from the surface of the resin, wherein the multiple recessed portions are formed by the removal of the reinforcing fibers through the etching step and the vibration step; and
an electroless-plated layer formation step of forming an electroless-plated layer on the surface of the fiber-reinforced member using the catalysts as nuclei through an electroless plating method after the catalyst adsorption step.

2. The plating method for a fiber-reinforced member according to claim 1 , wherein the etching step and the vibration step are performed at the same time.

3. The plating method for a fiber-reinforced member according to claim 1 , further comprising
a roughening step of roughening the surface of the resin prior to the catalyst adsorption step, wherein the roughening step is performed before or after the etching step.

4. The plating method for a fiber-reinforced member according to claim 3 , wherein a surface roughness Ra of the resin after the roughening step is 3 μm or more and 8 μm or less.
