HI,
I new to prepeg and want to try to make some parts without a mold, but instead use a 3D printed part core.
I´m going to make a hydrofoil wing that is about 600mm x 150mm.
The idea is to 3D print the core and then put on vari-preg 430 very carefully and trim to trailing edge of wing with precise overlapp, then a layer of easypreg with gloss layer out, and trim carefully.
Then cover with release film- again with no wrinkles. Put it into V-bag and cure oven.
I want to avoid any major grinding or sanding to avoid changing the wing profile- i would like to be able to only sand the trailing edge /fiber overlapp. and go directly to sand to 400-600-800g matt finish.
Do you think this is possible ?
