I'm working in a carbon fiber back seat for a recumbent bicycle and I'm wondering how thick the ribs need to be. The idea is to make it in 2 parts. The outside part which is basically cosmetic and the inside which is the structural part. Them bounded together. The problem is I have no idea how strong carbon fiber really is. I'm thinking about making each rib about 10mm thick (15 layers of 6K) Is this something reasonable?
By the way, the dimensions in the PDF are in inches.
Thanks
