← ScienceWhich outcome occurs when a polymer composite material exceeds its glass transition temperature?
A)Increased creep from hydrogen bonding loss
B)Brittle fracture from covalent bond breakage
C)Reduced stiffness from increased chain mobility✓
D)Enhanced strength from ionic bond formation
💡 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.
