What environmental factor can cause degradation of FRP pipe over time without proper protective measures?

• A. Ultraviolet light
• B. Saltwater exposure
• C. High humidity
• D. Cold temperatures

Answer: (A)

Ultraviolet (UV) light plays a significant role in the degradation of fiber-reinforced plastic (FRP) pipes over time. These materials are particularly susceptible to UV radiation, which can weaken the resin matrix that constrains the fibers, leading to physical deterioration, such as cracking or loss of structural integrity. Without adequate protective measures, such as UV inhibitors in the resin or protective coatings, prolonged exposure to sunlight can accelerate the aging process and ultimately compromise the functionality and longevity of FRP systems. This understanding is crucial for maintaining the integrity of FRP installations, especially in outdoor environments where direct sunlight exposure is unavoidable. Therefore, when designing or maintaining FRP piping systems, it's essential to consider the effects of UV light and implement appropriate protective measures to mitigate degradation risks.
