You can ultrasound and radiograph CF to do NDT. I think the challenge is just more that we have over half a century headstart working with Al in aircraft to understand their failure modes and how to adequately test for them. Our understanding of CF (+CF's inherent nature of having more sudden failures) makes designing adequate NDT regimes more challenging. That said, we are seeing much more CF (and CF composites) being deployed into commercial aerospace (famously the 787 wings, but also the A350,
