Hi,
I have question about pre-peg.
1) If I dont have special oven or autoclave I can made items from pre-peg carbon fiber?
Example...
2) I made mold.... Than I use pre-peg carbon fiber + vacuum bag/ pump and wait 2 days...
What happening? I can made something if I use this strategy? Or I need
obligatory
warming pre-peg?
3) I can use
kitchen
electric oven? Something like this...

Hi there,
to answer some of your questions:
- You wont be able to make prepreg parts without a GOOD oven. By good I mean an oven that can go up in temperature slowly and keep an good stable temperature for a while. Kitchen ovens arent very good for that. not saying impossible but you'll encounter many problems.
- By bagging prepreg and just leaving it, nothing will happen...I have some prepreg laying around that havent been in the freezer for over a year and still flexible and not cured.

Negative on the first question. You need an oven. The resin never really 'cures' without it, it just goes crispy and stiff.
You can use a kitchen oven for smaller parts, as long as the pre-preg you are using doesn't require a complex cure schedule. If you can just stick it in at 80 degrees and leave it overnight, a kitchen oven works fine.
