How does UV radiation affect Fiber Reinforced Plastic sculpture over time?

Fiber Reinforced Plastic (FRP) sculptures are widely admired for their durability and versatility. However, prolonged exposure to UV radiation can significantly affect their structural integrity and aesthetic appeal over time. UV rays, a component of sunlight, cause the polymer matrix in FRP to degrade, leading to discoloration, surface cracking, and reduced mechanical strength.

The degradation process begins with the breakdown of chemical bonds in the resin, which weakens the material and makes it more brittle. Over time, this can result in microcracks that compromise the sculpture's overall stability. Additionally, UV exposure often causes fading or yellowing of the surface, diminishing the artwork's visual impact.

To mitigate these effects, protective measures such as UV-resistant coatings, sealants, or strategic placement in shaded areas are recommended. Regular maintenance, including cleaning and reapplying protective layers, can also extend the lifespan of FRP sculptures. Understanding the impact of UV radiation is crucial for artists and conservators to preserve these artworks for future generations.
