Can I ask why you want a CF BP?
I think I've seen one used with an Inspiration rebreather

You may be best off making one yourself. Raw prepreg and a vacuum bag will likely cost less than a commercial offering (if one exists).
What he said. Seems like a rather odd material selection. Low density, prone to cracking (which can't be fixed), expensive, etc..

Why? If it's a weight issue, Aluminum is just as light but has much more structural rigidity. If it's a style thing, then you can get plenty of colors in backplates as well (or make your own).

I dunno those CF-wrapped tanks have really taken off 
OP
yes, I have even seen carbon fiber bibo tanks 
yes the weight is the issue specially when I travel far away on plane
carbon fiber weights much less than Aluminum ! and no way you can crack it ! if its well done
anyways if someone knows of anyone selling them please let me know
thanks

Where? Rebreathers, Paintball, and some commercial diving??

nonsense.
When the tank is bolted on and you're walking to the water, the plate is in bending (I see Tobin looking at the thread, so if I'm wrong about that he can correct me
). The compressive part of that load is taken by the resin. The bolts themselves are bearing against a hole which was drilled into the backplate (a process that could cause the fibers themselves to crack).Can you design an appropriate backplate? Sure. Will one you buy be appropriately designed? And if so, was it built to spec? Who knows?
Graphite Fiber Reinforced Plastic ("carbon fiber") in practice may give you about a 20-50% weight advantage over aluminum. But considering the low mass off Aluminum plates (mine is about .65kg, and I haven't used it in over 3 years), you aren't gaining much.
In any case, perhaps this question is better asked outside the DIR forum. Generally speaking, DIR equipment selection is based on how it performs underwater, not how convenient it is above water.

I was tempted to make a gold backplate as it might be a good hiding place and method of cross border transportation. Hope the TSA isn't monitoring this forum or I'll get the quadruple S treatment next time I go on vacation.
