I'm planning to make this bracket with CF but don't have a lot of experience working with it and need advice.
1) the radius of .5 in the ones with the ? mark. How small can I go? Thinking about using vacuum forming.
2) For the shape. I'm thinking about making a male in wood, lay the fabric on top and once is cure machining the contour. Is this a good idea?
3) What about the thread. Should I make a metal insert ?
Any advice would be welcome.
thanks

Since this is like an extrusion then I would find a metal channel section that is suitable dimensions and radius on the inside.
Then use this section as your female mould and make a carbon piece from inside the channel.
This will give you a moulded finish on the outside of the new part and a coarse finish on the back side depending of your process/technique.
For me I would use pre preg carbon only because it is so much easier than messing with the wet laid process but then you would also need an oven and vac pump etc to do it.
It could also be done with a wet laid technique easy enough though.
Release the part and trim to your overall shape.
Maybe you could bond a 2mm stainless steel plate to back side of the bracket that already has the 10 holes in place. Then when the glue is cured drill through the carbon too and then tap the threads.
Using this extrusion kind of mould you can make a length of carbon 500mm long and cut this up into a number of bracket parts?
To take it a step further you could alternatively make two metal channels to form a moulded finish on both sides of the bracket if needed. Layup over the inner channel mould and then sandwich the two moulds together.
