Properties and application of POSS nanocomposites in aerospace
ابوالفضل معین , عباس کبریت‌چی
In recent years, polymer composites have been used in various industries. In this article, the application of polymer composites containing POSS in aerospace industries and solid composite propellants has been discussed. The studis showed that POSS nanoparticles increase the mechanical properties of polymer composites so that they can be used in harsh space conditions. POSS nanocomposites have high thermal stability and low flammability. These advantages lead to its use in thermal protection systems of space shuttles, rocket combustion chambers, missile warheads and thermal blankets on solar panels. Also, the rigid structure of POSS silica makes it useful in protective coatings against atomic oxygen, thermal cycling, orbital debris, plasma, and extreme vacuum. The low dielectric constant of POSS is another advantage of these nanoparticles, which has led to its use in electronic components of satellites, telescopes, etc. The latest findings show that solid composite propellants containing POSS increase the burning rate and the efficiency of rocket engines. These cases have made research on the properties of POSS nanocomposites in space industries very attractive.
