← ScienceWhich risk increases when an epoxy adhesive degrades?
A)Component delamination under thermal stress✓
B)Oxidative embrittlement in a polymer matrix
C)Galvanic corrosion from dissimilar metals
D)Creep deformation at high stress levels
💡 Explanation
Component delamination increases because the Van der Waals force disruption within the epoxy causes reduced adhesion with substrates under thermo-mechanical cycling. This effect results from adhesive bond failures between layers, therefore delamination occurs rather than other failure modes like bulk cracking.
