What are the effects of prolonged exposure to shaded, damp environments on composites?
Prolonged exposure to shaded, damp environments can significantly impact the performance and longevity of composite materials. Moisture absorption is a primary concern, as it can lead to swelling, reduced mechanical strength, and delamination. In such conditions, composites may also experience chemical degradation, particularly if the matrix material is susceptible to hydrolysis. Over time, these factors contribute to structural weakening, compromising the material's durability and reliability. Additionally, damp environments can accelerate the growth of mold or fungi, further degrading the composite's surface and integrity. Understanding these effects is crucial for selecting appropriate materials and protective coatings to mitigate damage in humid or shaded applications.
