How do composite materials handle prolonged exposure to chlorine fumes?

Composite materials, such as fiber-reinforced polymers (FRPs), are widely used in environments with harsh chemicals, including chlorine fumes. Their performance under prolonged exposure depends on the resin matrix, reinforcement fibers, and protective coatings.

Epoxy and vinyl ester resins offer better resistance to chlorine fumes compared to polyester resins, as they form a tighter molecular structure that slows chemical penetration. Fiberglass and carbon fibers are commonly used, with carbon fibers providing superior durability in corrosive environments.

However, prolonged exposure can lead to matrix cracking, fiber weakening, and delamination. Protective coatings, such as polyurethane or fluoropolymer layers, can significantly enhance longevity. Regular inspections and maintenance are crucial to ensure structural integrity in chlorine-rich settings.

In summary, composite materials can handle chlorine fumes effectively with proper material selection and protective measures, making them suitable for industrial and marine applications.
