Detecting Flaws with Vibrations and Heat

Dec-02-18 A new flaw detection system uses vibration, ultrasound and heat to test for defects in advanced composite materials.

As useful as they are, the advancements in composite materials bring with them the need for more comprehensive testing methods. To that end, the team from Tomsk Polytechnic University created a hybrid testing method that exposes the material to a wide range of frequencies. Using a combination of resonant ultrasonic stimulation, scanning laser Doppler vibrometer and an infrared camera, the TPU system can detect defects through both sound and heat variations while also consuming much less power than traditional methods.
