Description
Technical field
The present invention relates to a kind of method that improves spacecraft with polymkeric substance and polymer matrix composite antigen oxygen peeling performance, specifically, be meant in the resin matrix of polymkeric substance and polymer matrix composite and add the antigen oxygen peeling performance that does not improve the spacecraft material with the nano-particle material of atomic oxygen reaction.
Background technology
Polymkeric substance and polymer matrix composite have a wide range of applications on spacecraft.When spacecraft moves in the Low Earth Orbit environment of space, most of polymkeric substance and polymer matrix composite can be subjected to seriously degrading of atomic oxygen in the environment, the thickness of material and quality can be lost, and performance also can degenerate, thereby have influenced the works better and the work-ing life of spacecraft.In order to ensure moving reliably and with long-term at rail of spacecraft, and prolong its work-ing life, improving spacecraft is very important and necessary with the antigen oxygen peeling performance of polymkeric substance and polymer matrix composite.
At present; antigen oxygen peeling method commonly used on the spacecraft mainly contains: (one) anti-atomic oxygen protective coating: it is to plate one deck supercoat at the material surface that is subject to degrade; atomic oxygen can't be contacted with the protected material of bottom, thereby play the effect of antigen oxygen peeling.This method of anti-atomic oxygen protective coating occurs the earliest, also is at present the most frequently used, as just having used protective coating to guarantee that it moves and work-ing life reliably and with long-term in a large number on the international space station.It is complicated that but this method brings for the structure of spacecraft, also can increase the difficulty of forming materials and processing.In addition, defective appears in coating easily, as: 1. when spacecraft moves in track, (this is called as thermal cycling to its surface temperature changing between ± 80 ℃ approximately, about 90 minutes of cycle), because the thermal expansivity of coating and primer is different, under the effect of long term thermal round-robin, thermal stresses between the two may make coatingsurface crackle occur; 2. the bump of space micrometeorite and rubbish fragment also can make coatingsurface defectives such as hole occur; 3. in the deposition process of coating and during the component processing moulding, coatingsurface also might produce defective.These defectives are in case form, and atomic oxygen will pass these defectives and primer reacts, the formation sapping, and finally cause coating to lose provide protection even come off.(2) change the elementary composition of material surface: mainly be the surface-element composition that changes material by surface silicon alkanisation or ion implantation (aluminium, silicon, yttrium plasma) these two kinds of approach, make its surface contain abundant aluminium, silicon plasma, thereby make material under the effect of factors such as space atomic oxygen or atomic oxygen and uv-radiation, form oxide skin (silicon oxide, aluminum oxide etc.).Because these oxide compounds are not react with atomic oxygen, thereby also just reduce the atomic oxygen erodes degree of material, improved the antigen oxygen peeling performance of material.This method is actually and has changed the elementary composition of material surface certain depth, and then under given conditions, material surface just can generate the new texture or the protective layer of anti-atomic oxygen.Spacecraft material after this method is handled, protective layer only are to exist at material surface, if suffer the bump of micrometeorite and rubbish fragment, equally also can lose efficacy; In addition, the bump of high energy particle also can change the molecular structure and the physics-chem characteristic of material surface, and for example the surface carbonization takes place and presents burgundy or the like.(3) development of new polymer materials: the molecular composition and the structure of redesign material, construct can antigen oxygen peeling novel material.This method mainly is to add the element that some can anti-atomic oxygen on the main chain of polymkeric substance at present, as fluorine, phosphorus etc., to improve the antigen oxygen peeling performance of material.But it can relate to the change of polymer production technology, bigger difficulty is arranged, and resulting material is except having preferably the antigen oxygen peeling performance, can satisfy the service requirements (as hot optical property, mechanical property, insulating property etc.) of spacecraft others, it be not immediately clear.
