I did a very simple test, using glass fiber to put it on the bottom side of a bowl, I believe it is the same as carbon fiber, and apply resin, and put it into vacuum bag.

and yes, I got the bottom side of the bowl as I wish.
However, the resin is not even distributed. When it is in the vacuum bag, the bowl is laced upside down, so the bottom surface is facing up, so the center is taller, the side ring is lower.
I can see a very obvious trend that the resin flew from center to side, the center, somewhere is not even covered by resin, I mean, the fabric is almost hollow there.
My question is when there are slopes, how to keep the resin stay at its place? Thank you very much!

Do you guys got my question? I mean, the resin always sink to the bottom before solidified, so when the mold is convex, how to keep the resin staying at its place and evenly distributed on the convex side? Thanks.
