Carbon Composite Calibration block

Hi,
I am looking for a source of Carbon Composite Thickness calibration blocks or step wedges.
Who markets these? Who manufactures them?

Re: Carbon Composite Calibration block Hi Godfrey,

I don't know what is your application, but when I was working on F18 aircraft, McDonald Douglas had their own supplier and was providing us directly with what we needed.

Maybe you could work with your client and come up with something that would be satisfactory to all.

Also, I don't normally advertise for manufacturers (Try to stay neutral), but Curtis Industries Inc, in Kittanning, Pensylvania, USA may be able to help. Again they are fabricating a wide variaty of Calibration pieces. Not sure about composite, but it's worth a try.

You can try NDT Engg Corporation or PH Tools USA for these blocks. I will give you the complete address by tomorrow. I did get some quote from them for CFRP Step Wedges, CFRP Laminates and Honeycomb Debond Standard

Re: Carbon Composite Calibration block NDT Engineering used to supply these and, I believe, used to make them for a lot of the aircraft companies.

Now they are part of Olympus I don't have anything to do with them, But assuming its the same people making them they should be worth trying.

Re: Carbon Composite Calibration block Pardon me for asking this dumb question, but why not get it made locally? A good machine shop or tool room should be able to machine them and once you know their thickness, you can set the velocity and thus use them as calibration blocks.

Am I missing something?

Regards.

It would be important to furnish pieces of the actual material to be tested, especially since composites vary so much. A machine shop theat is very good with metals might have difficulties such as meeting dimensional tolerances working with composites. Then there is the question of how tight these tolerances are required to be and whether the dimensional measurement must be traceable to NIST or some other recognized organization. Making sure of what the customer requires should be the first step.
