Area of Science:

  • Materials Science
  • Non-Destructive Testing
  • Aerospace Engineering

Background:

  • Carbon-fiber-reinforced polymers (CFRPs) are critical in aerospace due to their high strength-to-weight ratio.
  • Defect detection in CFRPs is essential for ensuring the safety and reliability of aero engines.
  • Existing inspection methods may have limitations in accuracy and efficiency for complex composite structures.

Purpose of the Study:

  • To develop and validate a continuous line laser scanning inspection technique for defect detection in unidirectional CFRPs.
  • To assess the capability of the technique in determining the size, location, and orientation of surface defects.
  • To evaluate the accuracy and detection rate of the proposed method for aerospace applications.

Main Methods:

  • Development of a continuous line laser scanning inspection system.
  • Analysis of material heat transfer using finite element software (COMSOL).
  • Implementation of an image processing algorithm for defect characterization.
  • Experimental verification of the technique on CFRP samples.

Main Results:

  • The line laser thermal imaging successfully determined the size, location, and crack angle of surface damage with high accuracy.
  • Positioning accuracy error for impact and fracture defects was less than 20%.
  • A 100% detection rate was achieved for defects positioned optimally relative to the heating area.
  • Fracture crack angle detection accuracy was within 10°.

Conclusions:

  • Continuous line laser scanning is a viable and accurate technique for non-destructive evaluation of CFRPs.
  • The method provides precise information on defect characteristics crucial for aero engine component maintenance.
  • This technique offers a promising approach for enhancing the quality control and safety of composite materials in aerospace.
