Do we have any material scientist among us?
I know what wood, aluminum, titanium, steel are but just realized I don't have clear understanding of 'Graphite'. How is it different from plastic or other polymer? What would be a good example of goods made of graphite around us?

Graphite is basically carbon fiber bonded together with a resin. It's not the same as pencil graphite, or graphite lubricant.

Graphite is one of the crystalline forms of carbon. Another crystalline form of carbon is diamond. Graphite is very soft while diamonds are very hard. Both are forms of carbon, but have different structures. The way carbon atoms align in a crystalline structure and the environmental conditions present at the time determines if carbon forms a hard diamond or soft graphite.

A typical example graphite is a pencil. The "lead" in a pencil isn't actually lead, but graphite. You should do some searches in Google to learn more, but here's a few links to get you started:

I'm not a materials scientist, so someone else may be able to give you more details.

As Craig said. Of course, tennis racquets are mostly made of graphite these days. So are the shafts of some golf clubs and fishing rods. The body panels on Formula 1 race cars are also made of carbon fiber/graphite. These are also used in some boats and airplanes. Basically, any application where light weight and strength are needed.

Actually almost all the parts of a Formula 1 car are made of carbon, with the exception of the engine and gearbox...
