What is the best technique to mold these parts, and redo them in carbon? infusion? Prepreg? Dimensions: 700mm x 350mm Thank's a lot.

+x+x+x+xWhat is the best technique to mold these parts, and redo them in carbon? infusion? Prepreg? Dimensions: 700mm x 350mm Thank's a lot. For the mold, gel coat and fiberglass would work. As for the piece, if it has to be light and strong, prepreg of infusion, if it's just a cosmetic part, no subjected to any efforts, just wet layup. Thank you very much, the pieces should be light and solid, but also cosmetic ... I'm thinking of opting for infusion, with 3D core ... and gluing the pieces with structural glue ... I strongly hesitate with the pre-impregnated, and buy the easy composite oven ... But will I really gain a lot compared to the infusion? Prepreg is the sure way to get an optimal fiber to resin ratio. It is possible to get nice parts with infusion (as nice as prepreg parts), but it's more of a trial and error process for every new part you'll build, it's kind hard to know how much resin you must use, the best places to put your fed and vaccum lines, things you may only get right after a few parts infused, and it's more time demanding. It's also possible that you do it right from the first time, but it's unlikely. Infusion has many potential problems, and it can be tricky to get it right. Prepreg is more straight forward. Very easy to work out resin requirements for infusion, it's simply reinforcement weight ÷ 1.5, plus 700g/sqm for infusion mesh, and a 10% wastage factor. Have to account for various infusion cores; 3D Core for example uses 330g per sqm per mm thickness. Feed lines are normally very logical unless you are doing a boat hull or bigger, no need to overcomplicate. Don't disagree that pre-preg is simple, but infusion doesn't have to be hard or complicated, it is also very simple. I would expect a bit of trouble using either process for the first time, but its a simple enough part so it should be fine either way. OP, if you plan on doing lots of stuff like this, pre-preg is a wonderful process. If this might be the only part you ever make, don't invest in pre-preg, the oven will be a waste.

What about ooa prepreg?

What about ooa prepreg? I am referring to OOA pre-pregs, standard pre-pregs are a bit beyond the realms of most hobbyists haha.

hello thank you very much for these details ... indeed there should only be two pieces ... so I will favor the infusion ;-) thank you very much for the resin ratio! awesome!!! thank you so much
