Summary
This study introduces a new thermal imaging dataset for composite materials, crucial for detecting subsurface defects in carbon fiber-reinforced plastic (CFRP) and glass fiber-reinforced plastic (GFRP) using pulsed thermography.
Area of Science:
- Materials Science
- Non-Destructive Testing
- Composite Materials
Background:
- Subsurface defect detection is critical for composite material integrity.
- Pulsed thermography is a key non-destructive evaluation technique.
- Characterizing defects in complex geometries remains challenging.
Purpose of the Study:
- To present a comprehensive thermal imaging dataset of composite materials.
- To facilitate the detection and characterization of subsurface defects.
- To support research in pulsed thermography analysis for CFRP and GFRP.
Main Methods:
- Pulsed thermography was applied to six composite plates (CFRP and GFRP).
- Defects were simulated using Teflon inserts with varying length/depth ratios.
- High-resolution thermal images were captured using an FLIR infrared camera.
Main Results:
- A dataset of 12 image sequences (approx. 2000 images each) was generated.
- Data covers planar, curved, and trapezoidal geometries.
- The dataset enables detailed analysis of defect signatures.
Conclusions:
- The dataset provides valuable data for advancing pulsed thermography analysis.
- It aids in understanding defect detection in diverse composite structures.
- This resource supports the development of improved NDT methods for composites.
