Description
Technical field
The present invention relates to a kind of simple carbon/composite material of silicon carbide manufacture method.
Background technology
Advantages such as that silicon carbide is that pottery has is in light weight, thermotolerance, wear resistance and corrosion resistance and good, therefore be widely used in every field such as various corrosion-resistant parts, heat-resistant part, wear-resisting wiping parts and cutting tools, particularly in space flight and aviation and auto industry field, be considered to make the most promising candidate material of internal combustion turbine and engine parts.But, also do not reach the level of practicability fully because the fracture toughness property of silicon carbide ceramics is too low.In recent years, in order to improve the toughness of silicon carbide porcelain, use continuous fiber reinforced silicon carbide to become a research focus.
Use carbon fiber-reinforced carbon composite, promptly carbon/carbon compound material can use under 2000 ℃ high temperature, and uses as structured material in the space flight and aviation and brake flange material.But carbon/carbon compound material begins to take place oxidation in the temperature province more than about 500 ℃, and in order to improve its high temperature oxidation resistance, it is an effective means that the silicon carbide ceramics processing is carried out in its surface or inside.
Carbon/composite material of silicon carbide is a kind of novel fiber strengthening ceramic matric composite (CMC:Ceramic Matrix ComPosite), it be by carbon fiber be Rankine, silicon carbide ceramics be the base matrix material.The making method of this material generally has following several: the impregnation of (1) organic silicide, thermal decomposition method (PIP:Polymer Impregnation and Pyrolysis).(2) chemical vapor infiltration method (CVI:Chemical Vapor Infiltration) and (3) lqiuid phase sintering method (LPS:Liquid Phase Sintering) also are silicon fusion method of impregnation (LSI:Liquid Silicon Impregnation).
Impregnation-the thermal decomposition method of organic silicide is a kind of organic silicide to be carried out a kind of technology that the thermolysis sintering of impregnation-thermolysis sintering-impregnation again-again carries out repeatedly, an impregnation and sintering process can only obtain fewer density increase and intensity and improve, so density and intensity in order to improve material, need repeatedly to carry out repeatedly this process, manufacturing cycle is long, is unfavorable for actual batch process.The chemical vapor infiltration method is a kind of more satisfactory manufacture method, can under the temperature about 1100 ℃, use, be suitable for making the goods of different shape complexity, can make highdensity goods, but its manufacturing cycle is longer, needs several weeks even thousands of hours sometimes.The benefit of lqiuid phase sintering method maximum is sintering reaction time weak point, can produces dense matrix material at short notice, helps mass production, therefore enjoys attracting attention of people.
Carbon/composite material of silicon carbide, according to the difference of manufacturing process, the performance of material also has very big difference.Several factors such as the volume fraction of the volume fraction of the same density of material of performance, carbon fiber kind that we can say carbon/composite material of silicon carbide and self intensity, carbon fiber, the arrangement mode of carbon fiber, silicon carbide, the volume fraction of carbon, void content, free silicon amount are relevant.
In the structured material of space flight and aviation, owing to need high-density and ultrahigh-temperature intensity, the main technique of using is the chemical vapor infiltration method, and for the general product for civilian use, since do not require the ultrahigh-temperature intensity of material, and need lower production cost, therefore many with silicon fusion method of impregnation.For example, still use carbon/carbon compound material now,, use only to be confined to satisfy the needs of general vehicle, heavy truck and train braking dish in aircraft and the F1 racing car because its manufacturing cost is very high in the brake flange field.Therefore countries in the world are all at the simpler manufacturing process of exploitation.
For example GE, Toshiba Corp etc. had once developed the direct molten method of soaking silicon in carbon dust and blending in of fibers body of using, but, make the silicone content that dissolves in matrix in this way too high, a lot of silicon will occur in the mode of free body, influence the high temperature use properties of material.Make in addition when making in this way, carbon fiber must carry out surface oxidation-resistant to be handled, and for example plate silicon carbide or boron nitride etc. on the surface, otherwise carbon fiber will react when sintering, has increased the complicacy and the manufacturing cost of manufacturing process together with silicon.Germany aerospace institute utilizes the carbon of vitreous state and the characteristics that silicon reacts hardly, and the silicon of molten state is immersed, and makes the part carbon generation silicification reaction of matrix, generates silicon carbide.This is directly to utilize carbon fiber and silicon not to react and carbon fiber-reinforced carbon/composite material of silicon carbide of making.
Japanese industry research institute uses the mixture of Si powder and resol to do matrix, carries out compound with carbon fiber.In rare gas element, carry out sintering then, utilize the method for reaction sintering to produce carbon/composite material of silicon carbide, but the void content in silicon carbide substrate reaches more than 30%, the more important thing is in the formation reaction of silicon carbide, the volume of matrix has reduced 38% more than, uses this this method can only obtain the high carbon/composite material of silicon carbide of void content.Though they are the silicon by adding fine particle more in matrix and organometallic polymer etc. afterwards, attempts to reduce the void content in the matrix, void content has more than 15% all the time.In order further to improve density, mixture matrix by silica flour and resol is carried out carbonization, at first form the compound body of carbon/carbon, then this compound body is carried out repeatedly the process of infiltration-recarbonize of resol infiltration-carbonization-more again, need to carry out about 5 times and then in vacuum or rare gas element repeatedly the liquid silicon infiltration at least and handle.
The someone proposes to use earlier chemical vapor infiltration technology to form carbon-coating around carbon fiber recently; And then use thermal decomposition method further to increase the thickness of carbon-coating, and use liquid silicon infiltration treatment process that the pyrolysated carbon-coating is reacted into silicon carbide at last, obtained carbon/carbon-composite material of silicon carbide.The matrix material that uses this technology manufacturing is compared with only using chemical vapor infiltration+liquid silicon infiltration treatment process or using thermolysis+liquid silicon infiltration treatment process, very big improvement has been arranged on during fabrication, and the matrix material of manufacturing is at the needs that also can satisfy the brake flange material that uses on train and the automobile on the performance basically.But this technology still is more complicated in the actual production manufacturing processed, uses chemical vapor infiltration technology still to need long manufacturing time in addition.
Summary of the invention
The purpose of this invention is to provide short, the simple carbon of operation/composite material of silicon carbide manufacture method of a kind of Production Time.This method can produce the carbon/composite silicon carbide ceramic material that is suitable for high temperature resistant and wear-resisting wiping.
For achieving the above object, the present invention takes following technical scheme:
A kind of simple carbon/composite material of silicon carbide manufacture method, this method comprises the steps:
(1), earlier resol and/or carbon-silicon compound resin dissolves in organic solution, insert silicon carbide powder and/or the Si powder that grain diameter is the 10-1000 nanometer and be made into mud solution, wherein, the weight ratio of resol and/or carbon-silicon compound resin and silicon carbide powder and/or Si powder is 3: 1-1: 3;
(2), then carbon-fiber cloth or short carbon fiber thin slice are immersed in the mud that obtains in the step (1), placed 2-12 hour, obtain preliminary-dip piece;
(3), the preliminary-dip piece that obtains in the step (2) is carried out drying;
(4), dried preimpregnation thin slice is carried out carbonizing treatment in vacuum or rare gas element, the temperature of carbonizing treatment is 900-1300 ℃, and carbonization time is 0.5-4 hour;
(5), will contain the vinyl polymer silicon polymer is dissolved in the organic solution, add silicon carbide powder and/or Si powder then, be made into mud, wherein, the weight ratio that contains vinyl polymer silicon polymer and silicon carbide powder and/or Si powder is 1: 5-5: 1;
(6), then a plurality of preliminary-dip pieces after the carbonizing treatment in the step (4) are immersed in the mud that obtains in the step (5), placed 2-12 hour, obtain the secondary preliminary-dip piece;
(7), with a plurality of secondary preliminary-dip pieces that obtain in the step (6) be arranged in laminate structure and and mud carry out drying together, be made into block matrix material after the drying with laminate structure, promptly make blank;
(8), the blank that obtains in the step (7) is carried out sintering in vacuum or rare gas element, the agglomerating temperature is 1300-1600 ℃, and sintering time is 0.5-4 hour;
(9), then with this blank material under vacuum or the protection of inert gas, under 1400-1800 ℃ of temperature condition, immerse in the silicon solution of fusing, the molten time of soaking is 5 minutes-1 hour, takes out this material, promptly manufactures carbon/composite silicon carbide ceramic material; Perhaps this blank material was put in the silicon steam of fusing in a vacuum 5 minutes-1 hour, and taken out this material, also promptly manufacture carbon/composite silicon carbide ceramic material.
