Thanks Doug and Mic,
How easy is impregnated carbon fibre to work with? Or do you need it oven baked?
Cheers

You might wrote how difficult is ..... LoL !!!!
forget this ; to do preimpregnated carbonfiber you need
A very big fridge to stock carbon rolls as you cannot let these up to minus 15°c (and use them on the time written onto the roll 3 to 5 months)
carbon fiber epoxy mold because they need to be cured at same temp than the parts so .....
Very big Autoclave ( it's an oven able to have vacumm inside and out side )
cost are from 60000 to 500000 euros as they have vacuum pumps and electronics system to cure parts following an hardening process extremly precise and depending of how the part is so each item need a specific programm to enter on the autoclave computer
I know some guys having tried to avoid all this professional process using sort of big painting furnace and look like vacuum system because they wanted to show that their part where in " Prepeg " !! But if you watch the result iis no more than a normal cured wet system epoxy added by vacuum bag and sometimes very dangerous stuff because they used Polyester mold in doing that simili process and when curing at 50 or 60 ° C the styrene have migrated into some plies and when they tested delamination there was a catastrophic result indicating that something wrong was there on big parts as front bonnets or large floor pan !!!!!
And nothing to tell about how the poor polyester molds where totally deformed due to this abnormal temp they had to suffer
Plus the fact that Prepeg that cures at low temps are twice the price and very rare to find and not avaible in many thickness or wave constitution
And most of these specific low temp clothes have to be cured after unmolding at 90 °C to get the right " strength ratio " named TPG
SO ...........................
