The search led me nowhere. 

Any input on how to get nice rolled edges on a part? 

Does it require prepreg or can it be done with infusion?

I'm guessing it requires a curvature backward at the edge. That would mean the part might be locked into the mold once cured if it involves the entire perimeter of a part, thus needing a multipiece mold. Perhaps a removable flange portion that provides the rolled edge once mated  with the actual perimeter flange?

another option could be a silicone based flexible perimeter that is one with the actual mold that would allow release without the need for more removable multipiece molds. 

Any insight?

Its all in the pattern/original part.

As long as the pattern has rolled edge, then as long as you place your flange appropriately and dont use too much filleting wax, then the rolled edge will be transferred to the mould and any parts produced from it.
