Description
Technical field
The invention belongs to field of inorganic nonmetallic material, relate to composite manufacture technique, especially a kind of preparation method of carbon fibre reinforced silicon carbide ceramic composite.
Background technology
In silicon carbide ceramics, add continuous carbon fibre, preparation carbon fibre reinforced silicon carbide (C
f/ SiC) matrix material, carbon fiber the mechanism such as extract by crack deflection, fiber in the breaking-down process of pottery, can strengthen intensity and the toughness of stupalith.
Existing C
f/ SiC composite manufacture technique mainly contains: chemical vapour deposition (CVI) technique, precursor infiltration and pyrolysis (PIP) technique, mud dipping hot pressing (SIHP) technique, liquid impregnation (LSI) technique etc.
The technological process of CVI is that the carbon fiber preform is placed the CVI stove, and reactant gases is delivered to preform backward its internal divergence on every side by the directed flow that is produced by pressure difference, at fiber surface generation chemical reaction and in-situ deposition.CVI technique prepares C
fThe major advantage of/SiC matrix material be can be under far below the temperature of body material fusing point the synthesize ceramic matrix, reduce the fibre property that the high-temperature chemical reaction between fiber and matrix brings and descend; The integrity that can also keep the fibre preforms body structure in preparation process realizes that near-net-shape prepares complex-shaped goods.It is very long that but CVI technique also exists preparation cycle, has larger density difference, the defectives such as the remaining a large amount of void content of matrix material along gas diffusion path.
The SIHP technological process is that SiC powder, sintering aid powder and organic binder bond etc. are made mud with solvent, and carbon fiber is spun into non-woven fabrics, the molded rear hot pressed sintering of slice module behind the mud dipping.The densification of material is mainly finished by liquid-phase sintering process.C with the manufacturing of SIHP method
f/ SiC matrix material density is higher, and defective is less, comparatively is fit to the preparation unidirectional composite material.But the SIHP method has larger difficulty to the preparation complex shaped components, and carbon fiber tends under High Temperature High Pressure and SiC matrix generation surface reaction, causes fibre property to descend, and is unfavorable for improving the performance of material.
The standby C of PIP legal system
fThe conventional process of/SiC matrix material is to adopt organic precursor liquid solution impregnation of carbon fibers preform under certain temperature and pressure, behind crosslinking curing, carries out Pintsch process under protection of inert gas, makes precursor be converted into the SiC ceramic matrix.The preparation temperature of PIP method is low, but with no pressure burn till, less to machinery and the chemical damage of fiber, and can prepare the member of large complicated shape.But the shortcoming of this kind technique also clearly, and the material densification needs several dipping-lytic cycles, and the production cycle is longer; And owing in the Pintsch process process, can produce small molecule by-product, from matrix, overflow, the porosity of resulting materials is higher, and difficulty has been prepared fully dense material; The chemical reaction of certain form easily occurs in precursor and fiber in cracking process, on the one hand fiber is badly damaged, and forms on the other hand the interfacial layer of strong combination, causes the material toughness not high.
LSI technique comprises the three basic process: at first prefabricated carbon fiber spare is put into airtight mould, adopted high pressure stamp or resin transfer mold technique to prepare fiber reinforced polymer materials; Then cracking in the high temperature inert environment obtains low density carbon based composites (C
f/ C); Adopt at last melt Si under vacuum by the wicking action processing of infiltrating, make the reaction of Si melt and carbon base body generate the SiC matrix.This technique can be by adjusting C
fThe volume density of/C and porosity are controlled the density of final matrix material.The preparation cycle of LSI technique is short, cost is low, the residual porosity rate is low, can prepare dead size, complex-shaped workpiece; But this technique is Shortcomings also: melt Si is when reacting with carbon base body, and inevitably meeting and carbon fiber react, and fiber is etched and causes degradation.
The present invention has overcome defects.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, the advantages of three kinds of techniques such as LSI, CVI and PIP is got up, provide a kind of and can either improve C
fThe problem that/SiC matrix material density is low also can effectively hinder Si to the preparation technology of the erosion action of carbon fiber.
