← ScienceWhich consequence results when thermal stress degrades epoxy-fiberglass composite materials?
A)Debonding reduces load-bearing capacity✓
B)Oxidation inhibits galvanic corrosion
C)Crystallization improves impact resistance
D)Plasticization increases tensile strength
💡 Explanation
Debonding occurs due to differential thermal expansion between epoxy and fiberglass via cohesive failure. Because interfacial adhesion weakens, the load transfer efficiency decreases, therefore decreasing structural integrity, rather than corrosion resistance or mechanical enhancements associated with crystallization or plasticization.
