Carbon Wheel Damage

I’ve run a set of CF BST’s on my track bike for years. No problem at all so far and obviously umpteen tyre changes.

But I do accept that carbon fibre isn’t the most reliable material when used in stress related applications. The weave, lacquer and curing process will always lack consistency whereas dealing with a metal/alloy will give time after time characteristics. Remember that submersible attempting a visit to the Titanic last year?

And I’m afraid to say OP, that wheel’s fucked. Do not use. But I think you know that. Not the end of the world and good that you spotted it…

 

Bet new swing arm not cheap !

 

Ultrasonic phased array (C Scan) NDT will detect internal discontinuities.

 

What did the manufacturer say about the rim's catastrophic failure?
The autopsy results would have been interesting.......

 

I've not heard as of yet mate

 

12,000 eur

 

Few years back

 

Will be very interested to see what they say.

 

I’d still use BSTs before mag alloy wheels. On my 2nd set now and so far so good.

 

So, it’s possible that once you have removed the wheel from the spindle, used a bit of tape, I reckon you could sell these to someone? If they are not happy, just claim that you don’t know anything about it and suggest it must have been the postage carrier?

 

Ah yes, formula one, that well-known mass-market product.
Carbon is still kept well away from where is gets damaged as you will find it is incredibly difficult and expensive to repair unlrss you are in formula one and simply throw it away.

 

All I have is the miserable experience of frequently breaking expensive stuff. Some of it gets repaired like fibre glass, ally and even Ti, but the carbon tank got junked and the cracked fairings are gathering dust

 

The fairings are for the track so could be patched up on the inside and re-used.
I am not doing that though because when I gravelled the 899 at Mugello the only thing that got me back in the game was the ease of cable tie sutures on the fibre glass side panels.
