Enhanced thermographic inspection of woven fabric composites by k-space filtering

Gaetan Poelman et al.

Summary: This paper introduces an improved infrared thermography method for detecting defects in woven fabric composites. The k-space filtering technique is applied to automatically decompose the thermographic image into a structured thermal background image related to the weave pattern, and a residual image representing other features (such as defects). The proposed method demonstrates enhanced performance in defect detection and sizing.

Multimodal optical excitation pulsed thermography: Enhanced recognize debonding defects of the solid propellant rocket motor cladding layer

Fei Wang et al.

Summary: The study demonstrated the effectiveness of multimodal optical excitation pulsed thermography in enhancing defect detectability and depth-resolution dynamic range for solid propellant rocket motor interfaces. By building a 3D thermal-wave model, proposing feature extraction algorithms, and optimizing the pulse thermography with PLSR and ICA, better detection of interface debonding defects was achieved. Analysis of characteristic profiles indicated that the 1st independent component was more effective in detecting defect depth and diameter.

Deep learning for defect characterization in composite laminates inspected by step-heating thermography

Roberto Marani et al.

Summary: This study presents a complete procedure for non-destructive analysis of composite laminates using step-heating infrared thermography and deep neural networks. The one-dimensional temperature profiles of the target surface are collected and fed into a compact network of convolutional filters to classify the resulting features for complete three-dimensional characterization of possible subsurface defects. Experimental validation showed successful classification and identification of defects of different depths in glass-fiber-reinforced polymer laminates by varying the duration of heat pulses.

Latest Advances in Common Signal Processing of Pulsed Thermography for Enhanced Detectability: A Review

Yoonjae Chung et al.

Summary: Non-destructive testing is a technique used in science and industry to evaluate the properties of materials, structures, or systems without causing damage. Infrared thermography is a promising technology for quickly inspecting large areas. Pulsed thermography faces difficulties in defect detection, but signal processing techniques can help improve its efficiency.

Inverse reconstruction of fibre orientation in multilayer CFRP using forward FEM and eddy current pulsed thermography

Q. Yi et al.

Summary: ECPT is unable to directly provide comprehensive information about layer levels such as fiber orientation, but can be used to estimate the thermal and electrical conductivities of multilayer CFRP samples through an iterative inversion procedure that processes experimental measurements and simulation data.

Automatic Defects Segmentation and Identification by Deep Learning Algorithm with Pulsed Thermography: Synthetic and Experimental Data

Qiang Fang et al.

Summary: This study explores the use of combining synthetic data with experimental data to enhance the performance of neural networks in infrared thermography non-destructive testing. The results suggest that this approach may enable training neural networks by merging inexpensive synthetic data with a certain amount of experimental database to achieve compelling performance from a limited collection of annotated experimental data in a real-world practical thermography experiment.
