Abstract

Composite honeycomb sandwich samples are commonly used because they offer a high strength-to-weight ratio, making them ideal for lightweight and durable structures. However, ensuring their structural integrity is essential for safety and performance. Multimodal NDT (Non-Destructive Testing) inspection and characterization of composite honeycomb sandwich samples is a critical process in various industries, including aerospace, automotive, and civil engineering. The use of NDT techniques makes it possible to verify the quality of the composite material and identify any defects. In this context, we provide a comparison of several techniques as nondestructive methods on a sample of interest to the aerospace industry and evaluates the parameters of their use: shearography, infrared thermography and laser ultrasonic. Using non-destructive testing techniques, it is possible to check the quality of composite materials and identify any programmed flaws. These techniques allow for frequent inspections without compromising the integrity of the material. This helps ensure the safety and reliability of products using composite materials. From the preliminary results it is evident that the combined use of the described non-destructive testing (NDT) techniques can significantly improve the reliability and accuracy of the quality control process for a wide variety of materials and defects.
