← ScienceWhich outcome results when rapid frictional heating breaks molecular bonds in high-temperature polymers?
A)Increased compressive strength develops
B)Char layer formation advances✓
C)Recrystallization kinetics accelerate
D)Glass transition temperatures decrease
💡 Explanation
Char layer formation advances because rapid surface heating induces Pyrolysis, breaking molecular bonds within the polymer matrix providing ablative cooling; therefore carbon-rich material forms, rather than maintaining structure under load like compressive strength.
