Abstract

PURPOSE:To produce easily a titled prepreg material which is a base material for a fiber-reinforced composite metallic material, by forming a metallic coating layer on the surface of inorg. fibers by composite plating combining electroless plating and electroplating. CONSTITUTION:Inorg. fibers, for example, carbon fibers 1 which are spread and are fixed to a frame 4 are immersed in an electroless plating bath soln. after a pretreatment so that a metallic coating layer is uniformly formed on the surface 1 of the fibers by chemical reaction. Then the fibers 1 have the lower surface resistance thus having the good condition for electroplating. The electroless plated fibers 1 are spread and extended in a plating frame 2 having negative electrode bars 3 and with the bars 3 as a negative electrode, and a positive pole plate is separately provided and the fibers are electropated in an electroplating bath soln. The prepreg coated uniformly and densely with the plating metal on the fibers is obtd. according to the above-mentioned method.

[θ] Coach ink on fibers Metal is formed by a combination of electroless plating and electroplating, and the details will be explained below with reference to Examples. In the production of prepreg used in the FRM of Fiber H1, the electroplated steel produced on the surface of P fibers has properties suitable for diffusion bonding methods such as denseness and adhesion. , Wet plating such as electroplating is an excellent method in terms of productivity. However, carbon woven fibers are extremely thin fibers with a diameter of only a few microns (μm), and they are made into a large number of 5,000 to 20,000 fibers. Moreover, since the electric resistance is definitely high at 2X10-3Ω, if electroplating is performed directly on the fiber Mf-, a large amount will be plated on the part near the power source, and a protruding plating layer will be formed easily. , it is difficult to obtain a flat surface. FIG. 1 is a plan view of an example of an apparatus for electroplating carbon P fibers, and FIG. 2 is a sectional view taken along line 1-1 in FIG. The frame 2 made of hard vinyl chloride is formed by fixing both ends of two long sides 2a placed in parallel to two short sides 2b also placed in parallel.1. The negative if(+'t fil 3) of stainless steel 1/s is set near both ends of the long side 2a in parallel to the short side 2b. There are about 120 depressions on the long side 2a, negative Wt, and the interval between Gokushin 3 is 300 (('I is made,

Fix one end of 1 to one short side 2b with adhesive tape,
Tension each carbon fiber 1 so that it is in contact with the negative electrode 3, and fix the other end to the other short side 21) with adhesive tape etc.-J
'/'T oThe frame 2, in which the leg fibers B1 are tensioned and fixed to a width of approximately 100 mm, is immersed in an electrolytic solution consisting of a dilute sulfuric acid solution of copper sulfur, and installed separately. The carbon fiber 1 is plated with copper by applying a DC voltage between the positive electrode ♂ and each negative electrode 3. When applying copper 1 [1, q, V) to carbon fiber using such a device, the electric resistance of the leg fiber XfL is high, so
The carbon fiber 1 is plated with copper only within 30 to 40 meters from the two negative electrode rods 3. In addition, when dispersing and spreading carbon fiber bundles, it is extremely difficult to disperse them into optical power, and some tens of fibers may remain in bundles with low fiber density. In such a bundle part, the outer 1Mt
It happens that only 14 are plated and the fibers in the center of the bundle are not plated with copper. Such a phenomenon makes it impossible to directly electroplate carbon fibers to make prepregs. The present invention aims to improve electroplating performance by lowering the electrical resistance of the surface of carbon fibers, and to uniformly electroplat even small fiber bundles as described above. This method is characterized by performing all pre-processing. Since the plating progresses through a chemical reaction in M-Fffl plating, the fibers are poorly dispersed and there are small fiber bundles with a slightly high fiber density.
Since it penetrates into the M bundle, it is possible to uniformly plate each fiber with copper. However, since the plating speed of thermoelectrolytic steel plating is extremely slow, making prepregs for FR and M using this method is disadvantageous in terms of productivity. However, as mentioned above, charcoal: P, fiber 11j fi'

“When using Fffl plating, gold W by plating
Even if the thickness of the layer to be applied is slightly 7'J+, it achieves its purpose; therefore, the slow plating speed (11'CO) is not an obstacle at all. The following describes the experiments conducted for the purpose of the present invention. First, a copper coating layer was formed on the surface of the carbon fiber by only applying a layer of 'l11.+V'. Figure 2-13 is made to apply 1J of i+ plating directly to the entire optical surface of carbon fiber.
FIG. 2154 is a plan view of L and T[ shown in FIG. The frame 2' made of hard υλ resin is parallel to the 1 side 2
It is formed by fixing both ends of a' to the short sides 2 and 2 of two trees placed in parallel, and supplying charcoal i rU firewood 1

The seven negative electrode rods 3 are made of stainless steel and have charcoal Z (fibers L) suspended between the short sides 2b under tension 11','li,

The carbon fibers were immersed in a copper sulfate bath plating solution of inl/ρ, and using a separately installed copper plate as the positive electrode and each negative electrode rod 3 as the negative electrode, plated the carbon fibers spread out in an area of approximately 100 vm x 300 m as described above. Plating was performed at a current of 9 A for 30 minutes. The prepreg made by straining in this way was subjected to MM, and heated in a hydrogen furnace at a temperature of 800°C and a pressure of 20k! ? //ci was fired to form F-M. FIG. 5 is a metallurgical micrograph (75x magnification) of a cross section of the FRM molded product thus prepared, and it can be seen that defective portions where diffusion bonding is insufficient even after pressure firing have occurred.

However, because the carbon fibers are uniformly coated with copper, diffusion bonding progresses sufficiently even when the pressure during firing is 201rg/crd, and the carbon fibers are uniformly dispersed. 5. No defects such as those seen in the figure are observed. If we further compare the above from the viewpoint of mechanical strength by 44%, we find that carbon fiber is 30 Vofi and copper is 70 Vofi.
