E-glass vs S-glass: the difference is:
A{'text': 'E-glass is for electronics only', 'label': 'C'}
B{'text': 'They are the same', 'label': 'D'}
C{'text': 'E-glass is the standard ELECTRICAL-grade general-purpose glass; S-glass has higher STRENGTH (S) for structural applications, at higher cost', 'label': 'B'}
D{'text': 'Cosmetic', 'label': 'A'}
Answer & Solution
Correct answer: C. {'text': 'E-glass is the standard ELECTRICAL-grade general-purpose glass; S-glass has higher STRENGTH (S) for structural applications, at higher cost', 'label': 'B'}
E-glass (electrical, ~3.4 GPa tensile, low cost) is the workhorse for boats, automotive panels, wind blades. S-glass (Structural, ~4.6 GPa, ~30% stronger) is used in defense and high-performance structures where cost permits.
