looking for a carbon fiber/plastic/fiberglass EXPERTS !!!

The thickness depends on the panel, and the curvature of the part. Different weights of fabric will also change the amount needed. For something flexible like the bumpers, 6-8 layers of 6oz fiberglass or carbon fiber would probably be sufficient.
The mold will be difficult to make of the bumpers, because they are flexible, and have sharp 90degree corners (around the edges). You don't want to have a distorted mold, although since the final product will be flexible it probably won't be a huge deal.
What is your goal for this? Weight savings?

weight savings will definitely be a +, my objective is to accomplish the complete body style of my imagination... something that isnt out there in the market.

i know i have to do more research, i wish i saved it, i was just looking at something, and they used 200g cf, than a white puffy thing that looked like something you would put on top of your mattress if its too hard to soften it, and then another layer of 200g cf, white thing was in between... any idea what that was? or if i need it, i thought it was just CF sheets and the hardeners of course, would i need other fabrics?

and you said 6 layers.. why 6 layers exactly?
what i used less
