Carbon-Carbon Composites for Disk Brakes
Porosity variation in carbon-carbon composites is easily distinguished with Ultran’s non-contact ultrasound technology from 100 to 500 kHz (based on thickness and attenuation of actual material).
Delamination between layers causes nearly full attenuation of ultrasound.
A robust technique using through transmission is currently employed on numerous production lines for quality and process control.
