Hi there,

I did some resin infusions now and my parts are quite ok. But now I want to make the next step and the part I want to make can be seen from every side, for example a rear wing. How do you make parts which can be lacked and have high gloss from two sides?

Thanks
Sebastian

a rear wing is usually a foam structure wrapped in carbon (and then several laquer coats, sanding and polishing) for one offs, or small numbers. or made in a two piece mold, usually in two halves, and the joined together, for serial production.
for monolithic pieces (or simple sandwich structures), like carbon sheets, two gloss sides can be achieved in ones step via vari, rtm, or prepreg press moulding.

Thanks.

the one step methods seem to be a bit different for a beginner

But what is the difference between vacuum resin infusion (which I used) and VARI? It seems like the same!? Should I skip the peel ply so that the bottom side is not rough and polish it afterwards?

So if you use a two piece mould and put the pieces together, how do you get smooth and round corners where you match the pieces? When I look at my actual products there is a thin and sharp carbon edge. Just sanding and polishing or is there a “Trick“?
