Which outcome occurs when a polymer composite material exceeds its glass transition temperature?

💡 Explanation

When a polymer composite material exceeds its glass transition temperature, chain mobility increases because weaker intermolecular forces weaken, leading to a reduction in stiffness. Therefore, reduced stiffness occurs, rather than creep, fracture, or enhanced strength which rely on different bonding changes.
