yes, not all parts are equal, but for this shape, the adjectives I used are almost universally valid. especially when you can make such a mold for like 15€. the only thing I can think of, why it should be done this way would be the surface optics. but usually machined carbon isnn't an eye catcher.
If you, for whatever reason, want to try it shaped of a carbon block, I would simply buy a carbon plate, cut it into stripes, and then glue them together. this will give you a much more uniform thickness, and less voids, compared to hand laminating. if you just glue stripes on, where material is needed, it would be much cheaper, too. and your cc time will come down.

+xis there a reason, why you don't laminate the carbon in a mold with a radius? or even the whole ring in one go?. it has to be a good reason, because it would be faster, much stronger and much cheaper. not all the items all equals and it should me mounted over a shaft, so the complete piece is not a chance. And I will laminate it in a mould with radius, then it will be cnc machined. The plate was the first trial.

+x+x+xIts possible to layup something that thick..you will need to do a lot of debulks to get decent consolidation. Ar you bending the cured or uncured panel? thanks, what do you mean 'debulk'?. I am planning to roll with roller to kill the bubbles , also taking care of resin ratio between Carbon weight and resin. I will use plain 0/90, 3K, 200 gr/m2 Carbon fabrics I would do a search on debulks as its a fundmamental of conposite manufacturing on most processes. What is the purpose of the part. If its structural whats the tolerance on your part. Will it be machined to the correct size? Are you going to do the complete laminate 80mm thick in one shot? I would look at doing it in stages and building up to the full thickness. debulk in spanish is also called 'consolidation', I know good the meaning of that. Thanks!!

+xDear All, I need to manufacture thick plates in Carbon fiber composite, 80 mm thickness, 40 mm width, 380 mm length. I would like to make them by hand layup, taking care of work by layers to avoid the exothermy bend or twist the plates. I am right?. Those plates will be then mechanized to make a kind of banana shape. I have epoxy lamination resin, so could I use it? Attached are two pictures. 1.jpg is the final shape to obtain assembling the mechanized pieces, and 2.jpg is the profile to obtain once mechanized the thick plate. your suggestions are welcome!   Theres no real reason it wont work, but it's going to be a long layup for sure! I'd get some comfy shoes for that job... Also, I assume by "mechanised" you mean machined? So you will mill the plates down into that banana shape? Why not just mould them in that shape to begin with?
