Experimental study on improving AO-resistance of resin using sol-gel method

  • 摘要: 为提高航天器用树脂基材料的抗原子氧剥蚀性能,将正硅酸乙酯(TEOS,Tetraethyl Orthosilicate)加入环氧树脂溶液中,采用溶胶-凝胶法,制备出SiO2/环氧杂化材料.在空间环境原子氧效应地面模拟设备中,对材料试样开展了抗原子氧剥蚀性能评估试验,总结了试验前后试样的质量、表面形貌和表面成分的变化特点,并分析了溶胶-凝胶所得杂化材料抗剥蚀性能提高的机理.分析认为:溶胶-凝胶反应过程中在树脂基体内生成的聚硅氧烷和SiO2,以及原子氧作用下杂化材料表面生成的SiO2保护层,是杂化材料抗剥蚀性能得以提高的主要原因.
