摘　　要：In this paper, the FEVE membrane structure material as the research object, the performance of the artificial accelerated aging was studied. The mechanical properties, surface color change, stain resistance and surface gloss retention after aging were tested. The test results show that the tensile strength and surface gloss retention of FEVE film structure materials decrease with the increase of artificial accelerated aging time, but the decrease is not large. After aging for 3000h, the tensile strength and surface gloss retention of FEVE film structure materials can still be maintained at more than 85%, and the surface color basically does not change. After aging for 1000h, the stain resistance grade of the sample remains unchanged, and the stain resistance grade starts to decrease from 1500h, gradually decreasing from 4-5 to 3-4 grade.
