I guess you are probabally right, I think of carbon fiber as strong in tension and compression but flexy under lateral loads, even though I know parts like handlebars are really stiff, I tend to think of carbon more like a fishing rod. If you were making the part out of two similar pieces of metal I'd think of it differently.yeah, it would do that but the rigidity of the carbon wouls take 3/4 of the load from the bolt i am guessing.
its going to fit tight like hammer in, then bolts to tighten the wedhe to no slop.
the backside needs a radius so there is not a sharp corner next to the
carbon.
I recently had a senior engineer explain that I needed to add more material to a v shaped die I was designing to keep it from spreading out, for some reason I was thinking, "hey this is metal it doesn't break or bend because it's thick and it's metal" when realize you've got an 80 ton press pushing on it you start thinking about metal a little differently. I guess you could always add material around the joint to beef up the carbon and keep it stiff just like you would if it were metal or wood or nacho cheese.
