Description
Technical Field
The invention belongs to the technical field related to aircraft protection structures, and particularly relates to a heat insulation bearing integrated material, a preparation method and application thereof.
Background
In the high-speed flight process of the high Mach number (Ma not less than 4) aircraft, the aircraft needs to face a severe pneumatic heating environment, the surface temperature of the aircraft can reach more than 1500 ℃, and the environment brings great challenges to a thermal protection system and a bearing structure of the aircraft: on the one hand, severe pneumatic heating causes a decrease in the elastic modulus and strength limit of the material, resulting in a decrease in the load-bearing capacity of the material; on the other hand, the material forms larger thermal gradient due to different thermal resistances, generates larger thermal stress, is overlapped with the flight aerodynamic load effect, and affects the stability of the structure; furthermore, the aircraft structure generates excessive deformation under the double effects of high-temperature thermal stress and aerodynamic force, so that the aerodynamic shape of the structure is damaged, and the safety and reliability of the aircraft are seriously affected. Therefore, the structural thermal protection problem of hypersonic aircrafts is one of the bottleneck problems restricting their development.
In conventional designs, the thermal protection material and the load-bearing structure of the spacecraft are developed in separate designs. The single thermal protection layer does not have bearing capacity, and needs to keep the integrity of the thermal protection layer, so that the weight of the aircraft is increased, and the defects of low structural efficiency, poor bonding connection maintainability, reduced mechanical property and the like are caused, so that the aircraft has great potential safety hazard. With the continuous progress of technology, an integrated design technology integrating heat protection, heat insulation and structural bearing functions has become one of key technologies for manufacturing various aerospace vehicles.
However, integrating the thermal protection function with the load bearing function must overcome the contradiction between the two functions in a single material: materials with strong bearing capacity, particularly metal materials, generally have good heat conducting capacity, which is unfavorable for heat protection of the structure, while light heat insulating materials such as ceramic materials have excellent heat insulating performance, but have poor mechanical performance and cannot bear the load. The current research on the structural heat protection integrated design mainly aims at optimizing and regulating the contradiction. For example, the united states aerospace agency has proposed in 2006 a corrugated sandwich structure integrated thermal protection system, the structure consisting of a high temperature titanium alloy upper panel, titanium alloy corrugated structural webs and an aluminum alloy lower panel, and filling the structural void with alumina fiber insulation material, the inclined web structure being capable of withstanding higher in-plane and aerodynamic loads, while the alumina fibers to some extent block and dissipate the high temperatures of the surface. But the ripple web in this structure is stronger to the heat transfer ability of structure inside, and the thermal short circuit effect is too high promptly, is unfavorable for the thermal-insulated design of structure. How to design a composite structure, the bearing capacity of the metal material and the heat insulation capacity of the ceramic material are better combined, which is the focus of the current integrated research of aircraft protection, so that the development of corresponding ceramic-metal composite technology, especially the design technology and the industrialized preparation technology of the ceramic-metal co-continuous composite structure, is needed in the art.
As disclosed in patent CN102102720B, a ceramic-metal co-continuous composite material and a preparation method thereof are disclosed, the method comprises the steps of preparing silicon carbide foam ceramic by a polymer pyrolysis method, and then injecting molten copper alloy into a foam ceramic skeleton by an extrusion casting method to obtain the ceramic-metal composite material. However, the pore structure of the foam ceramic prepared by the method is difficult to control, random, irregular or closed pore structures inevitably appear, the mechanical strength of the porous ceramic is reduced, the process repeatability is low, the controllability is poor, the space structure optimization design of the ceramic-metal composite material is greatly limited, and in addition, great pressure is required to be applied in the extrusion casting process, so that the structural integrity of the porous ceramic body is difficult to ensure.
As another example, patent CN115533080a discloses a method for preparing a gradient ceramic-metal composite armor, where a method of melt infiltration combined with hot isostatic pressing is used to fill a metal melt into a porous ceramic core plate formed by additive manufacturing, to promote further densification of the ceramic and metal, thereby preparing the composite armor. The ceramic-metal composite material prepared by the method has higher density and better performance, but has higher requirements on equipment, needs to build a high-temperature and high-pressure device, has complex process, needs to prepare an alloy ingot from metal firstly in the preparation process, and then heats the alloy ingot to a certain temperature higher than the melting point of the alloy ingot, so that the metal melt and the porous ceramic surface have better wettability, the infiltration process is slower, the production efficiency is low, the cost is higher, and the large-scale preparation of the ceramic-metal co-continuous composite material is limited.
