← ScienceWhich outcome arises when high humidity weakens fiberglass composite containing embedded ionic contaminants?
A)Accelerated galvanic corrosion of reinforcement✓
B)Increased strength-to-weight ratio overall
C)Improved resistance against thermal shock
D)Enhanced UV radiation tolerance externally
💡 Explanation
Fiberglass composite experiences galvanic corrosion when ionic contaminants create electrochemical cells in humid conditions, therefore, the metal reinforcing fibers corrode rapidly because differential aeration accelerates electron transfer, rather than enhanced strength or radiation tolerance.
