Which outcome occurs when excessive molecular vibration in a polymer composite arises from sustained high-frequency acoustic excitation?

💡 Explanation

Interfacial debonding is more likely because the acoustic energy promotes **resonance**, amplifying vibration at interfaces, thereby exceeding adhesive strength limitations. Therefore, debonding occurs, rather than vitrification, which requires cooling; crystallinity increases, or inhibited oxidation reactions, that is caused by free radicals at lower shear levels.
