Why Do Polymers And Composites Degrade Over Time? Have you ever wondered why certain materials like plastics and composites change or weaken over time? In this informative video, we'll explain the key reasons behind the degradation of polymers and composites. We'll start by discussing what polymers are and how their molecular structure influences their durability. You'll learn about the processes such as chain scission, oxidation, and hydrolysis that cause polymers to lose their strength and flexibility. We will also cover how environmental factors like UV exposure, moisture, and temperature fluctuations accelerate material breakdown. Additionally, the complexities of composite materials will be explained, including how environmental conditions impact both the polymer matrix and the reinforcing fibers. You'll discover how mechanical stresses combined with environmental factors can lead to cracks, swelling, and interface deterioration. Whether you're involved in material selection for aerospace, automotive, or medical applications, understanding these degradation mechanisms is essential. This knowledge helps engineers design longer-lasting materials and predict when components might need replacement. Join us for this detailed overview of how polymers and composites age over time, and learn how to make smarter choices in material engineering.
