Hypothesis
Can pulsed thermography effectively distinguish optical fibres from glass textile fibre bundles in GFRP composites?
Conclusion
The study found that modified pulsed thermography can effectively identify and track the arrangement of optical fibres embedded in glass fibre-reinforced polymer samples.
Supporting Evidence
- The study demonstrated that typical filtering techniques struggled to distinguish optical fibres from surrounding materials.
- A new filtering algorithm was developed to improve the detection of embedded optical fibres.
- The results showed that the proposed method outperformed traditional techniques in identifying the arrangement of optical fibres.
Takeaway
This study shows a way to use heat to find tiny glass threads inside a material, helping to keep things safe and working well.
Methodology
The study used modified pulsed thermography to evaluate the internal structure of GFRP samples with different arrangements of embedded optical fibres.
Limitations
The method struggled with sample surface roughness and environmental factors like daylight, which affected thermal measurements.
