too high cost or?
It is hard to form odd sharp like the body of a camera.
too high cost or?
Becoz it will fall apart when you drop it.
Its brittle.

If it's brittle, why would pro cameras use carbon fibre / Kevlar composite shutters?
I thought the main advantage of carbon fibre is shock absorbancy, that's why people use carbon fibre tripods. If following my line of thought, then I guess there really isn't a need for the added cost of carbon fibre bodies and lens because there's no shock to absorb on normal use?
Dude, my initial response was for your comment on the brittle features of carbon fibre without providing enough details. It's good that you know that there are different types of carbon fibre composites available. Do note that there were numerous industrial use of carbon fibre way before commoners we got to know them.Until im aware of what stresses the shutters go through during its life cycle, its alittle hard to answer your question. But what i can offer is that for material composites are that there is no one ideal material that can befit all applications.
And in the case of shutter, it might have been good to use CF.
You be glad to know that even for CF, there are various standards and qualities and a low grade CF (those car bonnets that you see..) dont exactly give you much of an advantage in terms of wgt to properties ratio. Its better off using PC or magnesium (which incidentally is shares the same density as some grades of CF).
As for cost... we are all made to believe that its expensive. but i assure you that its not.

there are too many grades of carbon fiber... dry carbon, wet carbon or carbon tube you're talking about? different carbon fiber configured for different purpose, there are slightly more brittle one to shatter absorbing impact (cars parts most probably)... there are very heavy duty one that you could stand and jump on a 4 feet x 4 feet less than 1 inch thickness (with internal metal wire frames) and it won't break if designed properly... there are some designed just to absorb and not transferring heat...
any of these would be too high cost for them.. unless you wanna buy a camera at least twice as much as current price... why? real carbon fiber are molded at 3 times higher temperature than plastic (plastic is about 150 to 500 degree celcius depending on resin)... plastic use the barrel to inject good enough or can say less critical... for carbon fiber the pressure applied is critical that they need a big oven like thingy to control it... and the older and best way to build CF stuffs, cut out carbon fiber sheets (looks like black cloth) and stack 2 to 12 ply depending on purpose... put on the mold, send in the oven, and the oven would heat it up and apply correct pressure to the resin injected... and keep the pressure until the oven is open...
i would want one because it's cool but i don't wanna pay the price since plastic is doing good... in this case where are those cameras going to sell to?
if you really like CF stuffs and don't mind the price... here's something you can consider... http://www.carbonfibergear.com/carbon-fiber-toilet-seat-cover/ (p/s: it's not that cold at night ;p)
