Problems solved by technology

The high-temperature oxidation and high-speed impact of atomic oxygen on the surface of the spacecraft will cause severe erosion of most organic materials, resulting in mass loss and thickness loss, degrading optical, thermal, electrical and mechanical parameters, resulting in a decrease in the strength of structural materials and functional materials. Performance goes bad

Embodiment 1

[0028] Example 1 Preparation of aluminum layer space multi-factor environment comprehensive protection material

[0029] Aluminum is heated to the temperature of its melting point (660.4° C.) to obtain an aluminum melt, and the aluminum melt is added to a commercially available three-dimensional graphene powder material, and aluminum accounts for 3% of the total weight of the aluminum melt and the three-dimensional graphene powder. %, using ultrasonic waves for individual dispersion, based on the capillary effect, the aluminum infiltrates into the three-dimensional graphene powder, cools and solidifies into a solid, and obtains a structure in which aluminum particles are tracklessly dispersed into the pores of the three-dimensional graphene.

Embodiment 2

[0030] Example 2 Preparation of comprehensive protective material for multi-factor environment in iron layer space

[0031] Heating iron to a temperature above its melting point (1535° C.) to obtain aluminum melt, adding the aluminum melt to commercially available three-dimensional graphene tube powder materials, iron accounts for the total amount of iron melt and three-dimensional graphene tube powder. 3% by weight, using ultrasonic waves to disperse, based on the capillary effect, aluminum penetrates into the three-dimensional graphene tube, cools and solidifies into a solid, and obtains a structure in which aluminum particles are tracklessly dispersed into the pores of the three-dimensional graphene tube.

Embodiment 3

[0032] Example 3 Preparation of aluminum layer space multi-factor environment comprehensive protection material

[0033] Mix the aluminum powder with the commercially available three-dimensional graphene powder material, the aluminum powder accounts for 5% of the total weight of the aluminum powder and the three-dimensional graphene powder, place it in a special high-temperature resistant container, and heat it to the temperature of the aluminum Above the melting point temperature, and then cooled and solidified into a solid, a structure in which aluminum particles are tracklessly dispersed into the pores of three-dimensional graphene is obtained.

Abstract

The invention discloses a space multi-factor environment comprehensive protection material. Liquid metal is mixed to a three-dimensional graphene block and permeates based on the capillary effect, the liquid metal is dispersed through ultrasound, and the protection material is formed through cooling solidification, or three-dimensional graphene and metal powder are well mixed, and the protection material is manufactured through solidification forming treatment by means of a cementation or sintering or high-temperature method. The metal covers 1%-10% of the total weight of the metal and the three-dimensional graphene. The invention also discloses a protection structure. Compared with the prior art, the strength of the space multi-factor environment comprehensive protection structure is improved by more than 200 times, and the mass of the protection structure can be at least reduced by 90% or more to protect the same space debris. Meanwhile, the protection structure has the shielding effect on electrons, protons, heavy ions, neutrons and elemental oxygen.

Description

technical field [0001] The invention belongs to the technical field of space material and structure protection design, and in particular relates to a structure suitable for space multi-factor environmental protection. Background technique [0002] During orbital operation, the spacecraft will encounter environments such as vacuum, cold and dark environment, solar electromagnetic radiation, charged particle radiation, neutral atmosphere, space debris, micrometeoroids, and plasma. Among them, atomic oxygen in low earth orbit can cause atomic oxygen erosion effect, space debris and micrometeoroid can cause impact damage effect, plasma can cause surface charge and discharge effect, electrons, protons, heavy ions, neutrons, etc. can cause single event effect , total dose effect, displacement damage effect, surface charge and discharge effect, internal charging effect, etc. Therefore, the space environment effect of the spacecraft in the space environment makes it necessary to pr...
