Unsaturated polyester fiberglass aging increasing attention has been concern in the western atmosphere. This paper tests the unsaturated polyester fiberglass in Wuhan, Jiangjin, Yuli and Lhasa Atmospheric Environmental Exposure and xenon lamps, heat and oxygen after accelerated aging surface topography, gloss, yellow index, weight loss and mechanical properties, and the use of FT-IR The DMA and XPS analysis of the microstructure of the polyester, and study the impact of different aging environments FRP the differences and fillers and coating of FRP aging aging, explored, and the correlation between indoor and outdoor fiberglass aging. The results show that: the western Atmospheric Environmental Exposure, glass, steel, as the exposure time increases, the decline in gloss, color yellowing after whitening shedding surface resin, glass fibers bare, strength first increased and then decreased, the curing reaction after aging pre Lord, the late degradation reactions; climatic factors on the extent of the effects of aging: Humidity gt; temperature difference gt; irradiation aging: Jiangjin gt; Wuhan gt; the Yuli gt; Lhasa. Indoor accelerated aging material intensity is first increased, then decreased, but the peak time is shorter xenon lamp aging. The heat is the dominant factor leading to deepen the color of polyester fiberglass alone cause the surface of polyester fiberglass resin cracking and falling off the dominant factor, the hot oxygen accelerated aging, the weak link in the main chain is vulnerable to attack oxygen molecules generated alkoxyl radicals , alkoxy radicals to form CO and C = O, C = O, then through the oxidation of O = CO, the final surface groups mainly of CO and O = CO The xenon lamp accelerated the old pre-degradation and thermal oxidative aging Similar Finally, the degradation of the O = CO groups and generate more free radicals lead to more degradation of the molecular chains. The xenon lamp accelerated aging than the thermal-oxidative aging of polyester fiberglass destruction fillers reduce the polyester glass steel's surface gloss and strength, delaying the thermal oxidative aging yellow index's decline, but to accelerate the xenon lamp aging yellow index of the decline. The coating reduces the strength of the FRP, but can effectively block the infiltration of moisture and oxygen FRP delay the aging of glass fiber reinforced plastic. The polyester fiberglass western Atmospheric Environmental Exposure aging and indoor accelerated aging correlation. Wuhan, Jiangjin, yuli and Lhasa exposed to aging and a xenon lamp and a hot oxygen accelerated aging of bending strength related factor: 36 and 2; while the xenon lamp and hot oxygen accelerated aging four regions exposed to the tensile strength of the correlation factor is the same as the , respectively: 12, 12, 12 and 3; shear strength related factors are as follows: 30,3.33,24,2.67,36,4 and 30,3.33. Xenon lamp aging than the thermal-oxidative aging accelerated faster.
