Wing supports

We are looking at creating some wing supports, which look something a bit like this:



This seems relatively straightforward by resin infusion - basically a flat sheet with the shape cut out, But I have a couple of questions:

1. Since these are structural members, they will be potentially supporting a fair amount of force so need to be strong so they do not buckle - to avoid this I was looking at making them around 8mm thick - is it possible to use two layers of 3mm Soric on top of each other, with CF either side? The other option which maybe easier is the 10mm 3D core, which would make them slightly thicker again - which I don't think will be an issue.

2. If I use the above approach to get the thickness (and therefore stiffness) that I require, and cut out the shape - what is the best way to finish the cut edge?

Finishing the cut edge of anything that uses coremat is something that I have struggled with, especially with thicker (used 3mm Soric so far) section; any advice would be welcome.

Thanks

Excellent, thank you. Will give it a go and see how we get on!
