Does anyone know to whom I turn if I want a bashed carbon fiber mountain bike frame checked out properly?
I'm told there are facilities out there who will undertake an x-ray (?) of the frame.
Is this correct?
Any links / details would be much appreciated.
Thanks
Tim

x- rays may show internal damage, but the only true test is a non destructive ultrasonic resonance test. This will be a 100% accurate

on whether the structure is safe or not to ride. Google search

Look in your local Yellow pages for NDT testers or find some local fabrication shop and ask them who does there NDT. This should start you off going the right way at least.

I had my helmet x rayed at A&E after a bad crash (where I only hit my head lightly and it was a brand new helmet!)... they were very good about it, but the radiographer was a friend of an ex.

I am following up on the NDT testing with me having emailed over some images to Caparo as they're local-ish to me.
Maybe it's something they can undertake, maybe not.
There is a British Institute of NDT so failing this, I'll asked other members on their books.

Ideally you need ultrasound to show flaws or cracks in composites

I use liquid penetration dye to test welds.
It may work on carbon fibre also.
Then again it may not ๐Ÿ™‚

Try Fibre HQ in Norwich, they also fix CF bikes and Wheels. I've had a set of Tri Spokes repaired by them.
