← ScienceWhich risk increases when thermal cycling weakens fiberglass epoxy?
A)Delamination from differential thermal expansion✓
B)Chain scission lowers average polymer chainlength
C)Hydrogen embrittlement accelerates crack propagation
D)Resonance lowers applied acoustic energy
💡 Explanation
Debonding occurs because thermal cycling weakens the adhesive Van der Waals force. Therefore, delamination from differential expansion increases, rather than chain scission happening generally; hydrogen embrittlement applies to metals; resonance involves frequency.
