anyone ever tried

when using a core material like soric has anyone ever tried cutting holes in the sheet to create a grid pattern?
so when the second layer of carbon is layed down it forms a ridge giving more structural strength.

just a thought really dont know if it would be of much benifit

It depends on what you classify as "structural strength", by removing the core in areas you are reducing the strength in that area from a bending aspect as you are reducing the effective depth of the section, you will also reduce the stiffness/increase the deflection of that area too. BUT as mentioned, you gain a hard spot for mounting points or impact areas as you create a thicker solid laminate so better bearing and point load distribution, also by joining the upper and lower layers between the core you can increase the torsional stiffness of the part with a bit of cleaver thinking
