Description
Technical Field
The invention relates to an aluminum-based composite material, in particular to a silicon carbide fiber bundle reinforced aluminum-based composite material and a preparation method and application thereof, belonging to the technical field of composite materials.
Background
The silicon carbide fiber has the advantages of high tensile strength and elastic modulus, good high-temperature strength and heat resistance, good wettability with metals, small fiber diameter and the like. The larger the volume fraction of the reinforcing SiC fibers in the silicon carbide reinforced aluminum matrix composite material is, the higher the thermal conductivity is, the smaller the thermal expansion coefficient is, and meanwhile, the silicon carbide reinforced aluminum matrix composite material has the advantages of high specific strength and specific stiffness, low density, wear resistance, fatigue resistance and good dimensional stability. The main method for preparing the silicon carbide fiber reinforced aluminum matrix composite material at present comprises the following steps: (1) The melting and infiltrating method is to infiltrate the liquid aluminum and the aluminum alloy into the fiber bundle or to make the fiber bundle pass through a liquid aluminum and aluminum alloy molten pool to make each fiber wetted by the molten metal and then remove the redundant metal surface to obtain the composite wire and then extrude the composite material. The disadvantage is that molten aluminum and aluminum alloys can damage the properties of the fibers when they are easily wetted. (2) Pressure casting method, in which molten aluminum or aluminum alloy is forced into a fixed mold cavity of a preform with a built-in fiber until solidification is completed. The disadvantage is that the casting pressure and the reinforcing fiber content have a great influence on the properties of the aluminium matrix composite. (3) The diffusion bonding method mainly refers to a manufacturing method of aluminum-based composite material obtained by laminating aluminum foil and fiber filaments or composite filaments or single-layer plates which are subjected to surface treatment and then soaked in aluminum liquid according to a specified sequence, and performing high-temperature pressurization diffusion bonding molding under the condition of vacuum or inert gas. In addition, the method also comprises a normal pressure sintering method, a hot pressing method and a high temperature extrusion method. The disadvantage is that the matrix is difficult to impregnate between the fiber tows, and the interfacial bonding is weak. (4) The powder metallurgy method is that the metal aluminum powder is sprayed on the arranged reinforcing fiber by plasma spraying method or is dispersed in acrylic resin (or polystyrene resin) to be coated to prepare a prepreg plate, the prepreg plate is overlapped alternately, and then is pressed and sintered in vacuum or argon at the temperature close to the melting point of aluminum to obtain the fiber reinforced aluminum-based composite material. The disadvantages are large fibre damage, uneven distribution and low content.
Disclosure of Invention
In view of the defects in the prior art, a first object of the present invention is to provide a silicon carbide fiber bundle reinforced aluminum-based composite material, which forms a tight package between an aluminum matrix and the surface of a silicon carbide fiber bundle based on the synergistic effect between the components, so as to greatly enhance the bonding force between the aluminum matrix and the silicon carbide fiber bundle, thereby improving the tensile strength and bending resistance of the material.
The second purpose of the invention is to provide a preparation method of the silicon carbide fiber bundle reinforced aluminum matrix composite, which adopts vacuum hot pressing and vacuum pressure casting, does not need to perform bundling or chemical plating treatment on silicon carbide fiber bundles, controls the bundling property and the wetting property of the aluminum substrate to the silicon carbide fiber bundles by controlling the vacuum degree, the temperature and the pressure, and controls the orientation distribution of the silicon carbide fiber bundles, thereby greatly improving the mechanical property of the material.
The third purpose of the invention is to provide application of the silicon carbide fiber bundle reinforced aluminum-based composite material as an aeroengine compressor component. The material is beneficial to interface combination of fibers and a matrix by adopting a vacuum hot-pressing preparation process, composite materials with different shapes can be designed according to a mould by vacuum pressure casting, excellent bending resistance and pressure resistance are given to the prepared material, and the mechanical requirement of an aircraft engine compressor can be met.
In order to achieve the technical purpose, the invention provides a preparation method of a silicon carbide fiber bundle reinforced aluminum matrix composite, which comprises the following steps: overlapping and laying the aluminum alloy plate layer with the oxide film removed and the silicon carbide fiber bundle layer in a mould, and performing vacuum hot pressing to obtain a composite material precursor; vacuum pressure casting the composite material precursor and the aluminum alloy plate layer with the oxide film removed, and cooling to obtain the composite material; in the composite material, the volume ratio of the composite material precursor to the aluminum alloy plate layer is 3-6.
The preparation method provided by the invention adopts a two-step method, firstly, partial aluminum matrix is promoted to completely wrap the surface of the silicon carbide fiber bundle through vacuum hot pressing and is partially immersed in the silicon carbide fiber yarns, thus not only having the functions of bundling and threshold limiting on the fiber bundle, but also strengthening the bonding strength between the fiber bundle and the aluminum matrix; furthermore, in the vacuum pressure casting process, the aluminum matrix is ensured to be at a liquid-solid phase junction point and to be in a flowing state under the vacuum casting condition, so that the aluminum matrix can be ensured to be tightly combined with the composite material precursor, and meanwhile, the fiber bundle can be further fixed, and the fiber bundle filament is ensured to be unidirectionally and uniformly distributed, thereby greatly improving the tensile strength and the bending resistance of the composite material.
In a preferable scheme, the number of the fiber bundle filaments in the silicon carbide fiber bundle layer is less than or equal to 1K.
Preferably, the monofilament diameter of the fiber bundle is 6 to 10 μm; the tensile strength of the fiber monofilament is 2.5-3.6 GPa.
As a preferred scheme, the vacuum hot-pressing condition is as follows: vacuum degree < 5 x 10 -3 Pa, the hot-pressing sintering temperature is 550-620 ℃, the pressure is 60-100 MPa, and the time is 0.5-3 h. Wherein the degree of vacuum is less than 5 x 10 -3 Pa is beneficial to the interface bonding of the fiber and the aluminum matrix; the hot-pressing sintering temperature is less than 550 ℃, or the pressure is less than 60MPa, or the time is less than 0.5h, so that the hot-pressing sintering is not beneficial to press forming, and the temperature is more than 620 ℃, so that excessive liquid phase is formed, and the subsequent pressure casting is not beneficial; pressures above 100MPa or times longer than 3 hours are detrimental to the integrity of the silicon carbide fibers.

Wherein the vacuum degree is higher than 5 × 10 -3 Pa, the interface bonding between the fiber and the aluminum matrix is not facilitated; when the casting temperature is lower than 660 ℃, the aluminum matrix can not be completely melted into a liquid state, and when the temperature is higher than 720 ℃, the interface reaction between the aluminum matrix and the fibers is not facilitated, and the performance of the composite material is directly reduced due to the serious interface reaction; casting pressures below 50MPa or times less than 0.5 hours are detrimental to composite formation, while pressures above 100MPa or times longer than 1 hour can damage the silicon carbide fibers.
Preferably, the thickness of the aluminum alloy plate layer is 0.05-0.15 mm, and the aluminum alloy plate layer is at least one of 1 series aluminum alloy, 3 series aluminum alloy and 6 series aluminum alloy.
