文摘
- •
A novel method achieves CFRP elastic modulus measurement.
- •
FBG reflectance spectrum analyses are the foundations of the method.
- •
3 dB bandwidth and center wavelength are chosen as reference indexes.
- •
Self-adaptive method is introduced to achieve experiment analyses.
- •
Absolute errors of reference indexes confirm the correctness of this novel method.
