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

Last question, before getting started ... I need it to be as solid as possible, how many layers of carbon fabrics do you recommend?
1 / 210g Plain Weave 3k Carbon Fiber (1st layer)
2 / 3mm 3D CORE PET 100 Foam
3 / 300g / - 45 Biaxial 3k Carbon Fiber?
4/ 650g 2x2 Twill 12k Carbon Fibre ?
5 / 375g 5HS 6k Carbon Fiber?
...
Thank you for all this precious information, I will ask you the photos of my work ;-)

It's hard to say, because when you increase the number of layers, you increase the strength AND the weight, so there is this trade-off, and we can't really say the number of layers without knowing what's the use of the part, which stresses it will be subjected to etc.

thank you, these are boat doors, currently they are made of wood covered with carbon, very very heavy ... so no weight problem, just as much resistance as possible for the hinges and handrail.
Thank’s a lot.

Way too asymmetrical in my opinion. And if anything you need the heftier skin on the outside. Probably you will even see the white core shining though the weave.

thank you, but I don't want to proceed as the original Parts ;-) I will make a mold (several parts) and make empty parts but as solid « hard » as possible ...
