    Abstract:

    To investigate the influence of thermal environment in orbit on the adhesive properties of J-47C
    structural adhesive, Tg and weight-loss temperatures of J-47C were acquired by DMA and TGA. Tensile lap-shear
    strength of the adhesive at different temperatures, before and after thermal shock, and after vacuum thermal cycle environment
    test was measured. The results show that the tensile-strength was of slightly changes after these environment
    tests. The J-47C structural adhesive can achieve the requirements of the special temperature environments announced
    by the usage of spacecrafts.
