How are you going to make a rocker cover skin with prepreg? it is VERY hard to do double curves.
Why would you need to make any of these out of prepreg? Why would a 'cover' of any sort need to be any stronger than 'wet lay'
Resin system? There is no 'resin system' in prepreg.. because it is exactly that 'pre preg'.
For this RESIN SYSTEM the temperature is ramped up slowly from room temperature to 125 centigrade over the space of an hour or so, then stay at temperature for an hour and a half to 2 hours before being allowed to cool back to room temperature before de-bagging, the pressure ramps up fairly quickly.
If there was no resin in 'pre-preg' it would not cure and essentially be dry cloth. pre preg is short for 'pre-impregnated' as in 'pre-impregnated with epoxy resin'
see this link from one our our suppliers to be proven wrong (2nd paragraph)
and the reason i am making them out of pre-preg is that i use it everyday at work,we dont use wet lay up as F1 teams (our customers) VERY VERY RARELY use it anymore, if they do its usually just trackside repairs, we run about 5 autoclave cures a day between 2 autoclaves,
and double curves are not a problem, they are actually pretty damn easy. that is, if you know what your doing and do regular vacuum debulks.
