Breaking news; I cut a little beaver-tooth out of the panel, and it separated in two like the red sea. Definitely created a dis-bond, just didn't notice until I cut out the piece. So in a summary, a pre-cured prepreg sheet wrapped in a Teflon tape or blue Flash tape worked. Too bad that our IR...

Just wondering Radagast, did it show up as a void/delam in your detection? or just a foreign object? By putting in a piece of steel or plastic would do the same trick IF it's just picking up a foreign object, no?

Sorry for getting back a little late on here. I tried both Teflon tape and Release tape (wrapped a cured prepreg sheet). The two panels came out, I couldn't see the defect using my IR camera, so we cut the panel to check out the cross-section. So void/delam. Frustration is amounting. Post...

By the way Kirby, my name on this forum is 'pkisKool' with a K, not 'pkisTool' with a T. LOL

Thanks all for suggestions. We are aiming for the delamination to be exact, not so much the porosity. But who knows, with application of enough mold release, it could cause a delam along with the porosity. And Kirby, our focused testing method currently is using the Infrared camera. There would...

It's an out-of-autoclave cure, using a technology called the Pharos(TM) oven. Basically a closed aluminum oven with heat lamps emitting UV rays. Going to try what Kirby suggested with the two layers of non-perforated FEP. Thanks ya'll

So you're suggesting inserting a pocket made of non-perforated FEP? We get up to about 250 F or so.

Hey, I'm doing some NDT research here at my job and my boss has asked me to create artificial voids within the carbon panels using prepregs. I've tried two methods thus far which both didn't work: 1)I've tried curing small sections of a prepreg sheet by sandwiching it between two aluminum...
