What are the effects of prolonged exposure to rooftop environments on composites?
Prolonged exposure to rooftop environments can significantly impact the performance and longevity of composite materials. Key effects include UV radiation degradation, which weakens polymer matrices and causes discoloration. Thermal cycling from daily temperature fluctuations leads to microcracking and reduced structural integrity. Moisture absorption and freeze-thaw cycles further accelerate material breakdown. Additionally, wind-driven debris and chemical pollutants contribute to surface erosion. Understanding these factors is critical for selecting durable composites and designing protective coatings to extend service life in rooftop applications.
