INDUSTRIAL APPLICATION FIELD The present invention relates to a simple method for manufacturing high-performance carbon composite materials. Prior art and problems to be solved by the invention High performance carbon fiber reinforced composite materials (hereinafter abbreviated as CFRC)
Regarding the simple manufacturing method of
In Publication No. 5349 and Japanese Unexamined Patent Publication No. 61-21973,
A new manufacturing method has been disclosed. These inventions relate to a method of mixing carbonaceous powder with a carrier resin, electrophoresing the mixture, depositing it on a carbon fiber base material using a deposition (electrodeposition) method, and molding and firing the mixture to obtain CFRC. It is. In the above invention, since it is necessary to conduct electricity to the carbon fiber base material during electrodeposition, a two-dimensional base material such as carbon fiber woven fabric, paper, matte, or nonwoven fabric may be used as the form of the carbon fiber base material. , a method is described in which a one-dimensional base material such as a string, filament thread, tape, etc. is used, and the material is formed by electrodeposition, laminated, wrapped, etc., and then fired. That is, in the methods of these inventions, short fiber base materials such as so-called chopped fibers and finely cut woven fabrics cannot be continuously energized, and the carbonaceous powder and carrier resin cannot be efficiently electrified. It cannot be used because it cannot be worn. In order to coat such short fiber base materials, dip coating, etc., which does not require electricity, is used, but these methods do not provide sufficient adhesion to the base material, so it is difficult to coat them during subsequent mixing operations. There is a problem in that the base material and the coating layer are likely to separate and fall off. However, CFRC made using forming methods such as lamination and wrapping methods tend to exhibit anisotropy in tensile strength, bending strength, shear strength, and physical and mechanical properties.
Although there are some applications for CFRC in which anisotropy can be used, there are also many fields in which isotropically reinforced CFRC is required, such as in structural materials. Means for solving the problem Electrodeposition is a method that can uniformly and firmly adhere carbonaceous powder to a base material in a desired ratio.
If this can be applied to short fiber base materials, CFRC with improved anisotropy can be made by randomly intertwining and mixing electrodeposited short fibers, shaping and firing. The conventional thinking was that electrodeposition was impossible because short fiber base materials could not be energized, but the inventors applied electrodeposition to a continuous base material while energizing it to adhere the carbonaceous powder and carrier. Then, it was cut into a desired length to obtain a short fiber base material coated with carbonaceous powder. In this case, there is a concern that the coating layer may separate from the base material due to the cutting operation, but since the coating layer made by electrodeposition has good adhesion to the base material, it is difficult to cut the coating layer as seen in coatings made by the usual dipping method. No significant shedding occurs. By mixing the obtained coated short fiber base materials, randomly entangling them, forming and firing them, it is possible to manufacture three-dimensionally reinforced CFRC. The content of the present invention will be described in detail below. As the carbon fiber base material used as a raw material in the present invention, a string made of bundled single fibers, a filament yarn, a woven fabric, a tape, a paper, a mat, etc. can be used. A carrier resin is attached to the finely divided carbonaceous powder and dispersed in a liquid to create a dispersion liquid. In this case, additives such as sintering aids and inorganic powders such as ceramics can be added to the carbonaceous powder. Thermoplastic and thermosetting resins that can be ionized in liquid can be used as carrier resins. Further, when mixing and dispersing the powder and resin, a dispersant and a surfactant may be used. Although it is easy to use water as the dispersion medium, a non-aqueous solvent can also be used depending on the purpose. Next, a carbon fiber base material is immersed in the above-mentioned dispersion liquid, and a direct current voltage is applied to deposit the carbonaceous powder and carrier on the base material. This operation can be carried out by feeding the substrate continuously or by batch processing. Subsequently, the base material is pulled up from the liquid, and if necessary, subjected to treatments such as washing and dried, thereby obtaining a coated base material. When a thermosetting resin is used as a carrier, drying must be carried out at a temperature and time range that does not allow the curing reaction to proceed too much. Thereafter, the coated base material is cut to an appropriate length or size, and a predetermined amount is placed in a mold and molded.
Conditions such as temperature and pressure during molding are based on resin and powder,
Adjust to appropriate conditions depending on the properties of the base material. At this stage, the molded body has a structure in which finely cut carbon fiber base materials are intricately intertwined, and the material is reinforced in random directions. If the cutting length is 1 mm or less, the entanglement effect will be small, and if it is 100 mm or more, workability will be poor. Regarding the shape of the molded product, it is sufficient to fill it into a mold of any shape and mold it, and there are fewer restrictions on the shape compared to the lamination method, winding method, etc. For molding, ordinary compression molding and isostatic pressing are possible, but isostatic isostatic molding is particularly desirable when an isotropic molded product is intended. The molded body may be made infusible, hardened, or
After performing treatments such as annealing and debinding, it is carbonized and fired to form CFRC. The firing temperature is selected depending on the intended use of the material, but 700 to 2000°C is appropriate in order to obtain good strength. If graphitization is performed, the temperature is further increased to 2000℃~3000℃.
Perform baking at ℃. By performing firing while applying pressure during firing, a high-density fired body can be obtained.
The pressurization method is selected from compression pressurization, isostatic pressure pressurization, atmospheric pressurization, etc. depending on the purpose. Examples Examples will be described below. Example 1 () Carbonaceous powder with self-sintering properties and calcined coke powder were mixed at a ratio of 1:1 and the average particle size was 5μ.
It was set as m. () The above powder was thoroughly kneaded with a polyacrylonitrile-acrylic acid electrodeposition resin and a solvent, and then dispersed in water to form a so-called anionic coating dispersion. In this state, the ratio of carbon powder to resin was 1:1 by weight. () Next, a PAN-based carbon fiber filament thread was prepared, and it was continuously supplied and immersed in the dispersion liquid, and at the same time, a voltage of 150V was applied between it and a stainless steel plate used as a counter electrode, using the carbon fiber as an anode.
Electrodeposition was carried out by applying electricity while stirring well. After electrodeposition, the yarn passes through a dryer and is dried in an atmosphere of 80°C. After drying, the weight ratio of the substrate to the electrodeposited material was 1:1.5. () Cut the electrodeposited base material thread into a length of 3 to 10 mm to make a covered fiber, and fill this covered fiber into a mold at a temperature of 200℃ and a surface pressure of 20Kg/cm 2
It was pressed and molded for 10 minutes. () Thereafter, the mixture was heated in air at 250°C and 280°C for 4 hours each to make it infusible while being clamped under a pressure of 20 kg/cm 2 . () 200Kg/cm 2 of this cured product in an inert atmosphere.
The temperature was raised to 1000°C at a heating rate of 30°C/Hr under a surface pressure of
The temperature was raised to ℃, held at 2000℃ for 1 hour, and then cooled to room temperature to obtain CFRC. The final shape of the CFRC was cylindrical with a diameter of 50 mm and a thickness of 40 mm. Comparative Example 1 () An electrodepositing dispersion using the same powder composition and resin as in Example 1 was used, and a woven fabric made of carbon fiber of the same quality as the filament yarn of Example 1 was used as the base material. The electrodeposition conditions were adjusted so that the weight ratio of the cloth and the electrodeposited material after drying was 1:1.5, the same as in Example 1. () Laminated 80 sheets of the obtained coated carbon fiber woven fabric,
It was pressure-molded in a compression press at a temperature of 150°C and a surface pressure of 150 kg/cm 2 for 20 minutes, and then infusible and pressure-fired in the same manner as in Example 1 to obtain a CFRC having the same shape as in Example 1. . Example 2 A coated fiber was made in the same manner as in Example 1,
Static pressure molding was carried out at 200°C and a pressure of 20 kg/cm 2 . Thereafter, it was heated in air at 250°C and 280°C for 4 hours each to make it infusible. This was baked by hot isostatic pressing at a temperature increase rate of 30℃/Hr to 100℃, and then heated to 2000℃ at a temperature increase rate of 100℃/Hr in an inert atmosphere at normal pressure.
It was held and fired at 2000°C for 1 hour. The final shape was CFRC having the same shape as in Example 1. Table 1 shows the results of measuring the density and bending strength of the above Examples and Comparative Examples.
