Best C-scanner for porosity analyses
(OP)
Dear all,
I'm interested in acquiring a C-Scan for carbon composites NDT. Our main issue are porosites within the laminate, mainly at the core of "T" joints. To do so, I believe we need an immersion (or jet projection) C-Scanner, but I'm not an expert on this field.
I would appreciate if you can comment on the following instruments:
1) TecScan (http://www.tecscan.ca)
2) USPC 4000 AirTech (http://www.dr-hillger.de/)
3) Sonatest (www.sonatest.com)
I also heard about laser ultrasound but have no much info on such instruments.
Thank you all for shearing thoughts!

RE: Best C-scanner for porosity analyses
I'm no NDI expert either but interact with the group every day. In my work with commercial aero T-stringers, radius filler areas (or noodles) are exempt from inclusion or porosity detection requirements.
I don't know of a method to inspect with ultrasonics as the geometry isn't suited. Technically I think it's possible though.. but again NDI isn't my role. Our equipment is custom; can't really speak about it but it's similar to what you've referenced.
We had a problem with our fillers that was corrected by increasing the overfill.
Regards,
Dan

I will be really interested into your feedback after testing. I am considering a few NDT solutions as well and should be trying Infra red imaging in the next few days (I am using sandwiches of small thickness)
RE: Best C-scanner for porosity analyses
I will certainly update on this topic once I decided for good.
Concerning the IR, I will acquire this thermal camera
JENOPTIK VarioCAM
HiRes Research 1.2 Mega
I will also update on few images later.
