Paint layer thickness measurement on composite
Paint layer thickness measurement on composite
(OP)
Dear all,
I have a general question about paint layer thickness measurements on Glass/PPS (Poly Phenylene Sulphide) thermoplastic composite aircraft structures.
Does anyone know an accurate measurement method to define the paintlayer thickness on a PPS structure ?
Besides this question, I have second thoughts about the ability of a lightning strike layer on a composite structure underneath a thick painting layer to do what it is suppose to do: conducting lightning strike in a proper way.
Any remarks are welcome.
Andre

This is the only direct measure that I am aware of. I have tried inumerable NDT techniques and found them less than repeatable for the ranges required.
Another approach is to use a metal test coupon attached strategically to the part and use the coupon with an Isoscope to validate thickness. I was able to sell this to Customer QA based on a comparison with the scratch technique.
Good Luck. This can be a hard task to get through.
Composites and Airplanes - what was I thinking?
There are gremlins in the autoclave!

We use it in the auto industry to measure paint on plastics.

However, in the field it is not usefull.
Cory, I hope that this equipement will be helpfull.
