| Abstract: |
| Based on a full investigation of literature on aging test of capsule materials at home and abroad, the research status of aging mechanism of capsule materials, aging test methods, selection of test objects, characterization and evaluation of performance effects were reviewed. There are four methods commonly used to characterize the aged capsule materials:morphology characterization, tensile testing, helium permeability characterization and chemical structure characterization. At present, there is a lack of unified evaluation index for the aging of stratospheric airship capsules, and most studies are insufficient in the aging performance verification of the capsule materials. The means and direction of follow-up research are proposed to provide a reference for the reliability testing research and development of the aeroplane capsules materials. |
