• Each Year Materials degradation
• costs billions of dollars, leads to serious
  injuries, loss of life and environmental
  pollution.

• Causes of material degradation
• Sunlight (UV rays)
• Rain
• Humidity
• Condensation
• Corrosion

• Potential problems
• Cracking
• Embrittlement
• Peeling
• Loss of tensile strength
• Delamination

• Materials at Risk
• Metals
• Protective coatings
• Polymers/Plastics
• Concrete
• Ceramics
• Paints/inks/dyes
• Other organic materials

3

• Objective To develop a better understanding of
  materials degradation through materials
  development, accelerating testing, and materials
  characterization
