Abstract: The simulations of geostationary orbit condition experiments to adhesive used on satellite, and the same experiments to adhesive adding nano-SiO 2 are experimented in this paper. The results show that adding nano-material obviously influence reducing space venting, restrain demage of electron radiation and thermal cycling. The results offer the foundation of bonding structure and material life reliability on long-life satellite in our country, emerge the prospect of nano-material using in the space.
