| Abstract: |
| Objective To study on influences of typical climate environment on aging properties of 2 kinds of plexiglass adhesive joints. Methods The natural outdoor exposure test of the two kinds of organic glass adhesive joints was carried out in Chongqing, Qingdao and Lasa. Rules of tensile shear strength and peel strength changing with aging time were studied. The aging mechanism of climate environment factors on the adhesive, the aging failure models of cementation structure were analyzed. Results High temperature, high humidity and ultraviolet radiation, of which high temperature and high humidity environment factor had larger influences on the performance; and the UV irradiation induced optical degradation speed was not as fast as that predicted according to theory. The adhesive process was the main internal factor which affected the mechanical behavior of adhesive joint. Conclusion The adhesive with good weatherability and suitable for adhesion of aviation plexiglass and polyester tape is selected, which can provide reference for the anti-aging design of the adhesive joint. |
