Car rear spoiler support legs

hi, looking for some advice. I want to make some carbon fibre support legs for my car rear spoiler.

The legs need to be approx 1 metre long, 200mm at the bottom tapering to 100mm at the top where it joints the spoiler. I have a vacuum infusion set up.

Ideally I want both sides with a gloss finish.

My plan was to use the following stack

200 grm 2/2 twill C/F  and 2mm Soric as follows;

C/F, soric, C/F, soric, C/F, soric, C/F

All sandwiched between two pieces of glass (in order to get a gloss finish on both sides)

This should end up about 5-6mm thick.

Qus 1 do you think this would be strong enough?
Qus 2 how can get radius on the leading edge / not end up with the exposed soric the the edges.

Many thanks.

If you can control your stack height you could bond a length of carbon tube in the edges to give a nice radius.

Might make the job too complicated but you may be able to put them in your dry stack and infuse the lot, not sure about this.
