“…In this regard, geographical location, the amount of oxygen in the surrounding area, air pollution and day and night circle of days are liable to play the second role. 1,3–6 In fact, due to cross-linking and chain scission at a molecular scale, micro-cracks along with brittlement would emerge on polymeric resin. 6–8 Polymer aging could be exerted physically and chemically.…”

“…5 The collaboration of other environmental agents such as moisture and heat with UV radiation is reported as “Synergism”, which had been the subjects of studies in previous attempts. 1 However, to gain better understanding of each environmental phenomenon, the main focus of this study is merely placed on the adverse effects of UV radiation and scenarios are defined in this regard.…”

“…Not only aerospace sector, but also other segments such as construction and municipality derive enormous benefits from their unparalleled properties. With this trend, given the fact that growing groups of such materials are susceptible to Ultra-Violet (UV) radiation in the long run, 1,2 it is of great importance to analyze the degree to which UV can cause damage to polymeric composites, especially in outdoor applications. Having studied this phenomenon, it is concluded that in such composite materials, the polymeric matrix is basically vulnerable to UV radiation compared to fibers.…”

The widespread use of fiber reinforced composites (FRP) in outdoor applications has prompted the question that whether ultraviolet radiation could wreak havoc on their lifespan. The main objective of this study is to investigate mechanical degradation of FRPs exposed to sunlight under natural circumstances on the long-term basis. On the one hand, experimental study is performed, before and after exposure, on laminated composites with different lay-up configurations cut from FRP pipes stored in outdoor space for a 1 year. On the other hand, a simple theoretical modeling in the form of user-friendly engineering tool is developed to estimate the residual ultimate tensile strength of laminated composites after exposure to sunlight. The destructive influence of sunlight on the mechanical performance of polymeric composites is taken into account through three different stochastic scenarios. Thus, stochastic modeling is implemented and the results are compared with experimental observations.
