I need to create a product in composite which has a similar strength to 6mm stainless steel. It's the two steel "plates" in the image attached

Any ideas on the type of layup best to achieve that? It'll be infusion. I appreciate about laying the weave in opposing directions per layer etc, it's more the weight of layup to use as in number of layers of 600 weight cloth. I'll need to put some aramid in it as well I think.

Twaron is black and it works rather as a background for first layer, you could use diolen, carbon, anything that is black, you can make soric smaller, and after everything is cured just stick one single sheet of cf to the back of part, so noone will see the diffrence in thickness, do you know what I mean?
