Carbon fiber composites can be tricky to manufacture, especially when dealing with large ply callouts and certain disbond types. You have to get the lay-up and cure process just right in order to obtain an accurate reading.
We have an eliminated a few items that we in the past had difficulty getting accurate results consistently, but we are happy to announce that there are still quite a few we still offer.
Please email us at sales@technandt.com to confirm price and lead time for the composites we offer.
Thanks,
