Carbon-Carbon Composites for Oven Fixtures

Porosity variation in carbon-carbon composites is easily distinguished with Ultran’s non-contact ultrasound technology from 100 to 500 kHz (based upon 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.
