← ScienceWhich consequence results when excessive static charge accumulation occurs in aerospace composite materials?
A)Electrostatic Discharge induced matrix cracking✓
B)Increased thermal conductivity through laminate
C)Reduced radar signature effectiveness
D)Diminished material tensile strength
💡 Explanation
Electrostatic discharge cracking results because electrostatic Discharge generates a high-voltage pulse which induces dielectric breakdown and micro-fractures. Therefore, cracking occurs rather than changes in conductivity or strength, because the energy concentrates at discharge points.
