Which outcome occurs when a polymer matrix composite is exposed to high vibration?

A)Interfacial debonding initiates crack formation.
B)Covalent bonds cause thermal expansion.
C)Decreased ductility results in buckling
D)Hydrogen bonds promote stress corrosion.

💡 Explanation

Interfacial debonding occurs due to fatigue, resulting in crack propagation because the vibration weakens the adhesive forces at the fiber-matrix interface. Therefore, debonding occurs, rather than general expansion, which might happen due to heating; corrosion won't arise spontaneously from vibration alone.
