How can premature fiber blooming in FRP pipe be prevented?

• A. By using a UV light inhibitor in the resin
• B. By applying a thermal barrier
• C. By increasing resin density
• D. By reducing exposure time to sunlight

Answer: (A)

Using a UV light inhibitor in the resin is crucial for preventing premature fiber blooming in fiberglass reinforced plastic (FRP) piping. Fiber blooming occurs when exposure to ultraviolet (UV) radiation leads to the degradation of the resin, causing the fibers to become visible or lose their structural integrity. Incorporating a UV light inhibitor during the manufacturing process helps absorb and block harmful UV rays, thereby maintaining the resin's properties and the overall strength of the FRP pipe. This not only prolongs the lifespan of the piping system but also ensures that it remains efficient and effective for its intended application. The other options, while related to FRP performance, do not directly address the specific issue of fiber blooming due to UV exposure. Applying a thermal barrier might help manage temperature-related stresses but wouldn't effectively mitigate UV damage. Increasing resin density does not necessarily prevent blooming and could potentially hinder other performance aspects of the FRP. Reducing exposure time to sunlight can be a part of a broader strategy to protect FRP, but it is not as definitive a solution as incorporating UV inhibitors directly into the resin formulation.
