Graphite for shelves, loudspeaker cases?

I own Tuneblocks feet made of Graphite for vibration control. Due to the layered structure, graphite seems well suited for vibration control. 
Now, I wonder why there are not more examples of this material be used in cases, replacing metal, for example.
Or, to build loudspeakers. 
Or, as shelves.
Is it not effective?
Too expensive?
Messy to work with?
My suspicion: it would be an excellent material but everybody wants to avoid the hassle working with it.

Well first off its not so much that its so great a material for vibration control as the combination of being affordable, easily machined, cosmetically attractive, and reasonably good vibration control. All that however is overshadowed by how hard it is to stabilize the surface so its not rubbing off making a royal mess of everything and wearing down to nothing in the process.

If it seems excellent that's mostly because DJ died and so nobody makes BDR any more. Find some used, learn the true meaning of excellent vibration control.

Carbon graphite is surely different from carbon fiber.

BDR were mixed with resin; Boston Audio seals a pure block (cylinder).

If memory serves DH Squares and DH shelves from Golden Sound are also a Graphite composite.
Geoff, Per your statement above, at least half your memory is correct (can't speak for the other half)... DH Squares are a Graphite composite, & very effective with the ceramic cones. 
All right, thank you. I was wondering whether I should replace the wooden shelf supporting my turntable with a graphite version. I believe some lacquer would help against the abrasion. Size is 400x450x25 mm, costs are 300 $
