Which structural collapse occurs when epoxy adhesive degrades?

A)Interface hydrogen bonding decreases severely
B)Chain scission dominates crosslinking buildup
C)Entanglement controls surface energy
D)Crystallinity initiates fracture propagation

💡 Explanation

Adhesive failure develops because reduced interface *hydrogen bonding* increases interfacial stress, causing crack initiation, therefore a loss of structural integrity happens; rather than matrix failure in other composites showing brittle fracture.
