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. |
