Best C-scanner for porosity analyses

Best C-scanner for porosity analyses

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 (
2) USPC 4000 AirTech (
3) Sonatest (

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

Hey Allcomposites,
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.

Thanks Dan for shearing your experience. I'm organizing a benchmark to properly choose the equipment. Will give feedback after testing.


RE: Best C-scanner for porosity analyses


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
HiRes Research 1.2 Mega

I will also update on few images later.
