Now, I noticed that graphite was at the bottom of the galvanic table. I tought graphite and carbon fibers was closely related? (we are getting seriously off-topic here, but I think this is interesting)
True, but the full answer is not so simple. Graphite is a form of carbon. Carbon is said to be graphitic (grid or graph-like) when the atoms are aligned in a particual crystalline formation. The properties of graphitic carbon (electrical, thermal, pyhsical) are quite different than for 'standard' non-graphitic carbon fiber, even thought these are both made of the same atoms. It's similar to the situation with diamond which is again a completely different material than graphite or carbon even though it is just another crystalline form of those same carbon atoms. And then there's Buckyball
