Description
Technical Field
The invention belongs to the technical field of metal matrix composite materials, and particularly relates to a method for preparing a carbon fiber reinforced aluminum matrix composite material by solvent dispersion freeze drying.
Background
The carbon fiber aluminum-based composite material has the properties of light weight, high strength and excellent thermal property, and has certain application in the industries of aerospace, vehicle transportation, petroleum and natural gas and the like, but the carbon fiber aluminum-based composite material has the problems of complex production equipment, limited product volume, poor mechanical property and the like due to the dispersion problem of carbon fiber and aluminum alloy, the interface problem of carbon fiber and aluminum alloy and the orientation problem of carbon fiber, so that the carbon fiber aluminum-based composite material has high production cost and poor economic benefit, and the application of the carbon fiber aluminum-based composite material is limited.
The existing short carbon fiber aluminum-based composite material is mainly divided into a liquid phase synthesis method and a solid phase synthesis method. The liquid phase synthesis method mainly includes a stirring casting method and the like. The stirring casting method has the advantages of simple process, low cost and the like, but the short carbon fibers are easy to agglomerate before being added, and the dispersion degree is low (for example, a method for preparing a short carbon fiber aluminum-based composite material by pre-dispersion treatment and stirring is disclosed in the patent document, and the document number is CN109207873B), while in the stirring preparation, the short carbon fibers are not uniformly dispersed under the simultaneous action of gravity and stirring force, and an ideal finished product is difficult to obtain (for example, a method for preparing a short carbon fiber reinforced metal-based composite material by mechanically combining electromagnetic stirring is disclosed in the patent document, and the document number is CN 108588591B). The powder metallurgy method has the advantages of energy conservation, environmental protection, uniform performance and the like, and is the most typical solid-phase synthesis method process. The temperature required by the preparation of the powder metallurgy composite material is lower, usually lower than the casting temperature and lower than the pressure impregnation temperature, so that the interface problem between the short carbon fiber and the aluminum alloy is avoided. The relative positions of the short carbon fibers and the aluminum alloy powder are fixed before and after the preparation of the powder metallurgy composite material, so that the prepared sample carbon fibers are uniformly dispersed. In the solution, the short carbon fibers and the aluminum alloy powder can be uniformly dispersed, and after the heating and drying, because the stacking density of the short carbon fibers is far less than the theoretical density, the dried short carbon fibers are mutually supported, and the aluminum alloy is deposited due to gravity, so that the short carbon fibers and the aluminum alloy powder cannot be uniformly dispersed. Patent document is a preparation method of carbon fiber/silicon carbide particle co-enhanced aluminum matrix composite, see document No. CN108823514B for details, and proposes that hydroxyethyl cellulose is dissolved in water to form colloid to uniformly disperse carbon fibers, but the speed is improperly controlled during suction filtration, so that the colloid solution is easily damaged, and the residual carbon fibers and aluminum alloy powder in the solution are agglomerated again.
Disclosure of Invention
In order to solve the problem of uneven dispersion of a mixture of short carbon fibers and an aluminum alloy in the preparation process of the carbon fiber aluminum-based composite material, the invention aims to provide a method for preparing a carbon fiber reinforced aluminum-based composite material by solvent dispersion freeze drying, which can uniformly disperse carbon fibers in the aluminum alloy and obtain the short carbon fiber aluminum-based composite material with high hardness, good wear resistance and high specific strength.
The invention adopts the following technical scheme: the method for preparing the carbon fiber reinforced aluminum matrix composite material by solvent dispersion freeze drying is characterized by comprising the following steps in sequence:
step one, performing surface degumming and modification treatment on short carbon fibers;
step two, dispersing the aluminum alloy powder and the short carbon fiber treated in the step one in an aqueous solution containing cetyl trimethyl ammonium bromide to obtain a viscous liquid;
step three, quickly freezing the viscous liquid obtained in the step two into a block in a liquid nitrogen atmosphere;
step four, freezing and drying the block obtained in the step three in vacuum to obtain a carbon fiber reinforced aluminum matrix composite blank;
and step five, carrying out hot-pressing sintering on the carbon fiber reinforced aluminum matrix composite blank obtained in the step four under vacuum to obtain the carbon fiber reinforced aluminum matrix composite.
Further, in the first step, the length-diameter ratio of the short carbon fiber is 10-2000.
Further, when the short carbon fiber is subjected to surface degumming and modification treatment in the first step, the short carbon fiber is soaked for 24 hours by acetone, then subjected to surface oxidation treatment, washed by distilled water and dried for later use.
Furthermore, the surface oxidation treatment mode is oxidation in air, concentrated nitric acid soaking oxidation or electrochemical oxidation.
In the second step, the aluminum alloy powder and the short carbon fiber treated in the first step are dispersed in an aqueous solution containing cetyl trimethyl ammonium bromide, and the process of obtaining a viscous liquid is as follows: firstly, adding aluminum alloy powder into an aqueous solution containing cetyl trimethyl ammonium bromide, stirring and dispersing for 2h, filtering to obtain aluminum alloy powder adsorbed with the cetyl trimethyl ammonium bromide, adding deionized water into the aluminum alloy powder adsorbed with the cetyl trimethyl ammonium bromide, adding a thickening agent, then adding short carbon fibers, stirring and dispersing for 30min, and obtaining viscous liquid.
Further, the concentration of the cetyl trimethyl ammonium bromide in the aqueous solution containing the cetyl trimethyl ammonium bromide in the second step is 0.5 wt% -1.5 wt%.
The viscous liquid obtained in step two has a viscosity of more than 5 mPas.
Still further, the thickener is selected from carboxymethyl cellulose, hydroxyethyl cellulose or hypromellose.
Further, in the fourth step, the freeze-drying process under vacuum is as follows: freezing temperature is lower than minus 40 ℃, and vacuum degree with absolute pressure lower than 10Pa, and vacuum freeze drying is carried out for 12-72 h.
Further, in the fifth step, the hot-pressing sintering is performed under vacuum, and the process for obtaining the carbon fiber reinforced aluminum matrix composite material is as follows: and (3) keeping the temperature and the pressure at 560-620 ℃ for 30min at the pressure of 30MPa, and cooling along with the furnace to obtain the carbon fiber reinforced aluminum matrix composite.
Through the design scheme, the invention can bring the following beneficial effects:
1. according to the invention, the surface of the carbon fiber is subjected to oxidation treatment, so that the surface of the carbon fiber is attached with enough hydrophilic oxygen-containing groups and is negatively charged in water. Cetyl trimethyl ammonium bromide is a water soluble cation that works well with anionic and amphoteric surfactants. The long carbon chain of the hexadecyl trimethyl ammonium bromide and the oxide film on the surface of the aluminum alloy powder are hydrophobic surfaces and can be connected in water through van der Waals force, so that the aluminum powder is positively charged after adsorbing the hexadecyl trimethyl ammonium bromide. The negative charges on the surface of the carbon fibers and the positive charges on the surface of the aluminum powder attract each other, so that the carbon fibers and the aluminum powder are dispersed in the water solvent.
2. According to the invention, through vacuum freeze drying, water in the mixture is slowly volatilized in vacuum, so that the dispersion state of carbon fibers and aluminum alloy powder in the mixture is not changed, and finally, the uniformly dispersed carbon fiber reinforced aluminum matrix composite material is obtained after vacuum hot-pressing sintering.
