Abstract: PURPOSE:To provide a method for plasma treatment of continuous materials capable of uniformly treating at a low cost of installation of electric source. CONSTITUTION:A treating container 1 for a plasma treating device consists of a cylindrical barrel 2, side plates 3 and 3a engaged through O-rings with both the ends of the barrel, a coil electrode 6 movably set close to the outer peripheral face of the barrel 2, and a suction pipe 4 for introducing a gas corresponding to plasma treatment to be applied to CFRP 10 and a vacuum evacuating pipe 5 for depressurizing the interior, both of which are laid on both the side peripheral wall, respectively, and a space 3b to be communicated and connected to an exhaust pipe 9 independent from a plasma generating space formed on the side plates 3 at both the ends of the treating container 1. The coil electrode 6 is moved in the longer direction of the CFRP 10 to treat the outer surface of the CFRP 10 by plasma.

Abstract: PURPOSE:To attain firm plating so that the plating film is hardly peeled by irradiating a body with low temp. plasma to remove the matrix resin component in the surface part to expose carbon fiber and then plating the fiber. CONSTITUTION:The surface of a plastic molded body containing carbon fiber 2 is irradiated with low temp. plasma to remove the matrix resin component 1 in the surface part and to expose the carbon fiber 2. Then the body is plated to obtain a carbon fiber reinforced plastic molded body with metallized surface. The weight DELTAW (g/cm ) of the matrix resin component per unit area removed by irradiation of low temp. plasma satisfies the inequality I. In the inequality I, R is the volume content (%) of the matrix resin component, H is the depth (cm) of the matrix resin component, and D is the average diameter (cm) of the carbon fiber. Thereby, the pretreatment for plating with a one-step and, inexpensive work can be provided without causing environmental pollution.
