Hi everyone,
I'm new to this, I just started watching some videos on Monday so I've no idea if this is a new idea or not, but I'm interested in copying some car parts without making moulds.
The idea goes something like this:
Cover the part in release agent then single sided prepreg, epoxy side out and secure edges with tape or temporary glue
Cover the prepreg tightly (no air bubbles) with thin clear flexible heat resistant gloss sheet gloss side in; e.g. silicone or latex
Seal the sheet behind, either to itself or a backing with vacuum connection
Cure it in an oven
Remove the laminate from the original
Add extra layers inside the first and cure using whatever technique you fancy
Gotchas:
The part has to be good for 100ish degrees
Would the epoxy stick to the silicone and does anyone know if latex would work?
BTW really excellent Easy Composites videos, infusion is so impressive.
