Assuming the same thickness then the CF parts should be about 30 - 40% lighter than ABS before paint depending on the quality of CF used. Standard plain weave carbon fiber has an approximate cured density of 0.6 g/cc while ABS has a density of about 1.03 g/cc. Hope this helps.:thumbup

Check that. I was WAAAAYYYYY off. I re-ran my calcs and cured CF has an approximate density of 1.5 g/cc while ABS plastic seems to have a density between 1.03 - 1.20 g/cc. Therefore for the same thickness CF will actually be heavier than ABS. I'm assuming, though, that CF parts are in general slightly thinner than ABS parts. If I'm wrong in that assumption let me know.
