| Abstract: |
| The objective of this work is to investigate the corrosion aging behavior of glass fiber reinforced resin matrix composites in the severe marine atmospheric environment. Field exposure test on composite materials in the atmospheric environment of South China Sea reef was carried out for different periods. The corrosion aging morphology characteristics and mechanical properties evolution rules were analyzed. Based on the accumulated data, the grey prediction model GM (1,1) was established. Furthermore, the results were compared with that in other typical marine atmospheric environments of Qingdao, Xiamen and Sanya. With the extension of the exposure time, the fibers of the composites were exposed seriously in the atmospheric environment of the South China Sea reef, and the flexural strength of the composites decreased. The accuracy of the grey model GM (1,1) established based on the flexural strength data reached grade 1. Compared with other typical marine atmospheric environments, the flexural strength of the composites showed a downward trend with the decrease of latitude. Using the grey model GM (1,1) to predict the aging behavior of the composites in the severe marine atmospheric environment can achieve high prediction accuracy. The main environmental factors affecting the mechanical properties of the composites are irradiation, followed by relative humidity and temperature. |
