alleryStart learning →Modulus of typical CARBON fibers is approximately:
A0.1-1 GPa
B230-700 GPa (range depending on PAN-based standard vs ultra-high-modulus pitch)
C3000 GPa
D10-20 GPa
Answer & Solution
Correct answer: B. 230-700 GPa (range depending on PAN-based standard vs ultra-high-modulus pitch)
Carbon fibers span a huge property range.
**Standard-modulus PAN-based:** ~230 GPa. Intermediate: ~290 GPa.
**High-modulus pitch:** 500-700 GPa.
Strength typically decreases as modulus increases.
Compare to E-glass (~70 GPa).
