Description
Technical Field
The invention relates to a composite material and a preparation method thereof, in particular to an ultra-light high-strength fiber reinforced aluminum-lithium alloy composite material and a preparation method thereof.
Background
The carbon fiber and the silicon carbide fiber have the excellent performances of light weight, high temperature resistance, corrosion resistance, aging resistance, high strength, high elastic modulus, low thermal expansion coefficient and the like. The fiber reinforced metal matrix composite has high specific strength and specific modulus, and is widely applied in high technical fields with strict requirements on component quality, such as aerospace, war industry, automobile products and the like.
High performance, light weight and high stability have been the goals pursued in material development. Taking an aero-engine as an example, the weight of the aero-engine is reduced, the gas temperature of the aero-engine is increased, and the thrust-weight ratio of the aero-engine can be effectively increased. The blades of the fan section and the compressor section account for the main part of the blades of the aero-engine, and researches show that when the blades of the engine are reduced by 1kg, the corresponding blade casing of the fan is reduced by 1kg, a transmission system is reduced by 1kg, meanwhile, the engine structure and the wing/body structure of the airplane are respectively reduced by 0.5kg, so that the weight reduction of the airplane is very important due to the iteration effect caused by the weight reduction of the fan structure, and the requirement is that the structural quality of the blades of the engine is lower, the aerodynamic stability is better, and the temperature resistance is higher.
Lithium is the lightest metal element in the world and has a density of only 0.534g/cm 3 And the lithium is the only alloying element which can improve the performance and reduce the density, and the lithium is added into the metal aluminum as the alloying element to form the aluminum-lithium alloy. When 1% of lithium is added into the aluminum alloy, the density of the alloy can be reduced by 3%, the elastic modulus can be improved by 5% -6%, and a remarkable aging strengthening effect can be obtained. The aluminum lithium alloy is adopted to replace the traditional 2000 series and 7000 series aluminum alloy materials, so that the weight of the airplane parts can be reduced by 10-20%, the material rigidity is improved by 15-20%, and the aluminum lithium alloy has the advantages of light weight, high elastic modulus, high specific strength, high specific rigidity and the like, and also has high fracture toughness and good corrosion resistance. However, the A1-Li binary alloy has a high anisotropy and plasticityThe toughness level is poor, and the like, so that alloy elements Cu and Mg and trace elements Ag, ce, Y, la, ti, mn, sc, zr and the like are generally required to be added so as to precipitate a strengthening phase and improve the comprehensive mechanical property.
By an extrusion casting method, the aluminum lithium alloy is impregnated into the fiber reinforced composite material, so that the weight of the material can be effectively reduced, and the damage resistance, the temperature resistance, the rigidity, the strength and the designability of the material are improved. When the aluminum lithium alloy is filled, because the wettability of the aluminum lithium alloy and the fiber is poor, an interface reaction can occur in the compounding process, so that the fiber is damaged, and the toughness of the composite material is reduced, a titanium oxide interface layer needs to be prepared on the surface of the fiber preform structure, the titanium oxide stability is good, and the performance of the fiber in a high-temperature aerobic environment can be ensured.
The Chinese patent with the granted publication number of CN104264083B discloses a carbon fiber reinforced aluminum lithium alloy composite material and a preparation method thereof. The composite material is prepared by mixing and sintering pretreated carbon fibers and aluminum-lithium alloy powder, wherein the volume fraction content of the carbon fibers is 1-10%. The preparation method mainly comprises the steps of firing, coarsening, neutralizing treatment, ball milling and mixing and vacuum hot pressing sintering of the carbon fiber. By regulating the volume fraction of the carbon fiber, the density of the aluminum lithium alloy can be reduced, the strength and toughness of the aluminum lithium alloy are improved, and the anisotropy of the aluminum lithium alloy is improved.
The invention discloses a silicon carbide and silicon particle reinforced aluminum-copper based composite material and a preparation method thereof, belonging to the field of particle reinforced metal-based composite materials, and the publication number of the invention is CN 105803293B. The composite material consists of silicon carbide, silicon and aluminum-copper alloy, and the weight percentage of the silicon carbide is as follows: 15-25 wt.%, silicon: 45-50 wt.%, aluminum copper alloy: 25-40 wt.%; the silicon carbide and the silicon particles are uniformly distributed in the aluminum-copper alloy matrix as a reinforcing phase, and the aluminum-copper alloy matrix forms a three-dimensional space net structure.
The national invention patent with the application publication number of CN104213057A discloses a copper-plated carbon fiber reinforced aluminum lithium alloy composite material and a preparation method thereof. The composite material is formed by mixing and sintering copper-plated carbon fiber and aluminum lithium alloy powder, wherein the volume fraction content of the copper-plated carbon fiber is 1-10%. The preparation method mainly comprises copper plating of the carbon fiber, ball milling and mixing and vacuum hot-pressing sintering. By regulating the volume fraction of the copper-plated carbon fiber, the density of the aluminum lithium alloy can be reduced, the strength and toughness of the aluminum lithium alloy are improved, the anisotropy of the aluminum lithium alloy is improved, and the density of the aluminum lithium alloy is reduced by more than 5% compared with the density of the common aluminum lithium alloy under the condition that the mechanical properties of the aluminum lithium alloy are close.
Although the preparation of the fiber reinforced composite material can improve the performance of the material, the wettability and the interface compatibility between the alloy and the fiber are not considered, and a pore defect may occur inside the composite material; the composite material based on the aluminum-lithium alloy is superior to the common aluminum-based composite material in specific rigidity and specific strength, and is superior to the common aluminum-based composite material in mechanical properties such as thermal shock resistance, yield strength, compressive micro-creep resistance and the like; the powder sintering method can avoid or reduce the harmful reaction of aluminum and carbon fiber, but because of the strong activity of the aluminum-lithium alloy, the aluminum-lithium alloy is difficult to avoid oxidation even if strictly protected in the sintering process, and the powder can cause safety problems such as explosion and the like.
