What are the effects of prolonged exposure to high humidity on composite materials?
Prolonged exposure to high humidity 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. Over time, the polymer matrix may degrade, weakening the material's structural integrity. Additionally, high humidity can accelerate chemical reactions, such as hydrolysis, further compromising the composite. To mitigate these effects, manufacturers often use moisture-resistant resins or protective coatings. Understanding these challenges is crucial for industries relying on composites in humid environments, such as aerospace, marine, and construction. Proper material selection and maintenance can help extend the lifespan of composites under such conditions.
