Definitions

  • This invention relates to an electroplating method for carbon fiber strands and apparatus therefor.
  • carbon fiber-reinforced con- posite materials which use carbon fibers as reinforcing fibers has been striking.
  • metal-coated carbon fibers are used as reinforcing fibers for electrically non-conductive materials such as thermosetting resins, thermoplastic resins, rubbers, papers, etc.
  • composite materials result having excellent mechanical properties and greatly improved electric conductivity.
  • EMI shield materials Electro Magnetic Interference
  • thermoplastic resin composite materials reinforced by metal-coated carbon fibers using thermoplastic resins such as polyamide, polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonate, polyacetal, polysulfone, an acrylonitrile- butadiene-styrene resin, polyethylene terephthalate, polybutylene terephthalate, polyphenylene oxide, etc., as the matrix material
  • thermosetting resin composite materials reinforced by metal-coated fibers using thermosetting resins such as an epoxy resin, an unsaturated polyester resin, a phenol resin, etc., as the matrix material are excellent EMI shield materials having good mechanical properties and good formability.
  • carbon fiber-reinforced metal composite materials wherein the same metal as used for coating carbon fibers is used as the matrix material, are excellent as light-weight structural materials, electrically conductive materials, slide materials, etc.
  • one method involves passing an electric current through a metallic roller and then bringing a carbon fiber strand into contact with the roller to pass the electric current to the carbon fiber strand, but in such a method it is impossible to bring every filanent of the carbon fiber strand into contact with the roller, and therefor the electric current is passed through carbon fibers which are not in contact with the roller by the contact with the carbon fibers which are in contact with the roller.
  • the specific resistance of carbon fibers is of the order of 10 -3 ⁇ cm, which is much larger than the specific resistance of an ordinary metal of about 10 6 ⁇ cm.
  • the contact resistance between the carbon fibers and a roller is large enough to generate heat, and the metal coating formed on the carbon fibers by electroplating tends to be oxidized by oxygen in the air and also by ozone generated by sparks occurring between the carbon fibers and the roller, which results in the occurrence of uneven color tone of the metal-coated carbon fiber strand, and the so-called plating defects such as burnt marks, lateral stripe marks, etc. If the metal coating is oxidized, the specific resistance of the metal-coated carbon fiber strand is increased, reducing the effect thereof as an EMI shield material.
  • An object of this invention is to provide an electroplating method for carbon fiber strands capable of overcoming the above-described difficulties and causing no uneven color tone and plating defects, and also to provide an apparatus for performing the method.
  • a further object of this invention is to provide a method for continuously applying electroplating uniformly onto every filament of a carbon fiber strand and to provide an apparatus for performing the method.
  • a continuous electroplating method for a carbon fiber strand which comprises continuously introducing a carbon fiber strand into an inlet of a metal plating bath and removing the carbon fiber from an outlet of the metal plating bath and applying an electric current to the'carbon fiber strand in a liquid or an inert gas atmosphere outside of the metal plating bath and performing electroplating in the metal plating bath with the carbon fiber strand as the cathode.
  • a continuous electroplating apparatus for a carbon fiber strand for performing electroplating with the carbon fiber strand as a cathode, comprising an electroplating bath having an electric current applying section to the carbon fiber strand disposed in a liquid or an inert gas atmosphere outside the plating bath.
  • carbon fiber strand in this specification is meant a carbon fiber strand or a graphite fiber strand usually composed of from about 100 to 100,000, and more generally from about 1,000 to 50,000, continuous fibers.
  • the application of an electric current to the carbon fiber strand is generally performed by passing an electric current through a conductive roller such as a metallic roller and contacting the carbon fiber strand with the surface of the roller.
  • a conductive roller such as a metallic roller and contacting the carbon fiber strand with the surface of the roller.
  • the whole conductive roller or at least the contacting portion of the conductive roller with a carbon fiber strand is disposed in a liquid or an inert gas atmosphere.
  • the application of an electric current to the carbon fiber strand is performed at the position of the carbon fiber strand outside of the plating bath and in this case, the section of the application of electric current to a carbon fiber strand may be the inlet side or the outlet side of the plating bath, or may be both sides of the plating bath, but it is particularly preferred that an electric current is applied to a carbon fiber strand at the outlet side of the plating bath.
  • the liquid for use in this invention may be a non- electrolytic solution but is preferably an electrolytic solution.
  • the liquid for use in this invention if the liquid is inactive with respect to the fibers to be plated, however, when two or more plating baths are used and the section of applying electric current to the carbon fiber strand is disposed before at least one plating bath, it is preferred to use, for example, an aqueous solution containing the same component or components as that or those of the plating bath, and more preferably an electrolytic solution having the same composition as that of the plating bath, or an aqueous solution containing only the main component of the plating bath at a concentration from at least 20% of the concentration thereof in the plating bath to less than the concentration of the main component in the saturated solution thereof at the plating temperature.
  • the concentration of the composition in the aqueous solution is slightly lower, preferably more than 5% lower, more preferably more than 10% lower than that of the plating bath, since the concentration of a plating bath tends to increase during plating.
  • the main component of a plating bath is meant a salt of the metal which is plated on fibers.
  • the aqueous solution as described above can be used as the liquid, but the aqueous solution need not always necessarily be the same as the aqueous solution, and water and any other aqueous solution of an electrolyte .
  • an inorganic salt for example, NaCl, Na 2 CO 3 , KCl, NH 4C l, CuS0 4 , NiS0 4 ZnCl 2 , etc., can also be used.
  • the concentration of the solution is controlled so that the specific electric conductivity is preferably within the range of from 1x10 -2 to 1 ⁇ -1 ⁇ cm -1 , more preferably from 2x10 -2 to 5x10 -1 ⁇ -1 ⁇ cm -1 .
  • the inert gas for use in this invention is, for example, N Z , Ar,, He, etc.
  • the conductive roller for the application of electric current be disposed at the outlet side of the carbon fiber strand.
  • the generation of heat by the contact resistance between the conductive roller and a carbon fiber strand can be minimized since the contact portion of the roller with the carbon fiber strand is in the liquid, whereby the oxidation of the coated metal formed on the fibers by electroplating does not occur.
  • the contact portion of the roller with the carbon fibers is in an oxygen-free state since the portion is in the inert gas atmosphere, whereby the oxidation of the coated metal by high temperature oxidation, ozone oxidation, etc., does not occur even when heat is generated by the contact resistance. Accordingly, a metal-coated carbon fiber strand having neither uneven color tone nor so-called plating defects such as burnt marks, stripe marks, etc., can be obtained in this invention.
  • the electric plating method of this invention can be used for plating a metal such as Cu, Ni, Cr, Zn, Cd, Pb, Sn, Au, Ag, etc., or alloys of at least two these metals, which can be used for ordinary electric plating.

  • the inside of the seal box 2 is filled with an inert gas such as N 21 Ar, He, etc., the pressure of which is slightly higher than the atmospheric pressure so that oxygen in air does not enter. Since the seal box 2 is connected to the plating bath 11, the seal box is shielded from external atmosphere. An electric current is applied to the carbon fiber strand 5 by contact with the surface of a conductive roller 1 for applying electric current placed in the seal box 2 or a liquid bath 3 ( Figure 2), whereby a metal is plated on each filament of the carbon fiber strand 5 in the plating composition 4.
  • an inert gas such as N 21 Ar, He, etc.
  • the electric current applying roller 1 is disposed in a seal box 2 as shown in Fig. 1 or in a liquid bath 3 as shown in Fig. 2 so that, in the latter case, the contact portion of the roller 1 with the carbon fiber strand 5 is in a liquid 12 in the bath 3.

  • Numerals 13 and 14 show guide rollers.
  • Fig. 3 shows the use of two or more plating baths and gas seal boxes which can be used in the manner of the apparatus shown in Fig. 1.
  • Fig. 4 shows the use of two or more plating baths and liquid baths :which can be used in the manner of the apparatus shown in Fig. 2.
  • each filament of a fiber strand Upon applying plating to each filament of a fiber strand, it is required to form proper space among the filaments for impregnating a liquid plating composition in the spaces among the filaments and also it is required to reduce the current density, and prolong the treatment period, and to adjust deposition of a metal onto the fiber in order to prevent bridging of the plated coating formed on the surface of the fiber strands, which disturbs the impregnation of the plating liquid composition into the inside of the fiber strand.
  • An aqueous electrolytic solution containing the main component of the plating bath composition is applied to a carbon fiber strand so that the inside of the carbon fiber strand is impregnated with the solution.
  • the application of the electrolytic solution onto a carbon fiber strand is performed by passing the carbon fiber strand through a bath containing the electrolytic solution or by spraying the electrolytic solution onto the carbon fiber strand by a shower, etc.
  • the content of the electrolytic solution impregnated in the carbon fiber strand is usually up to 200% by weight, and preferably higher than 5% by weight, based on the weight of the carbon fiber strand.
  • the elctrolytic solution usually contains, for example, a nickel salt, a Na, Ni or ammonium chloride, and a pH buffer in the case of nickel plating.
  • the electrolytic solution which is applied in a preliminary step to the carbon fiber strand may contain a nickel salt alone, which is the main component in the case of nickel plating, or may contain a nickel salt, a chloride as described above, and a pH buffer.
  • the concentration of the electrolytic solution for use in the case of preliminary application to a carbon fiber strand is from 20% of the concentration of the plating bath composition to less than the concentration of the saturated aqueous solution of the main component in the plating bath composition, more preferably from 50% of the concentration of the component to 90% of the concentration of the saturated aqueous solution of the component. If the concentration of the electrolytic solution is less than 20%, the difference of metal ion concentration between the surroundings of the carbon fiber strand and the central portion thereof in the plating bath is liable to become large and the thickness of the metal coating becomes uneven to cause the formation of lateral stripes.

  • the roller or bar composed of a metal, glass, ceramic, etc., and having a radius or a curvature radius of 10 to 100 mm is preferably used. If the radius or curvature radius is less than 10 mm, the carbon fiber strand is damaged and filaments are cut to form fuzz, and if the radius or curvature radius is over 100 mm, the spreading of the carbon fiber strand becomes insufficient. By spreading the carbon fiber strand, every filament constituting the carbon fiber strand is uniformly plated without forming lateral stripes.
