This isn't really an application for epoxy+carbon. There are some briefcases wich are partial made from flexible carbon fibre. These are made from flat sheets of carbon fibre cloth in a transparent silicone matrix. From there on you could use it to some degree like regular cloth to tailor things.

Hello, im looking to start up maybe in the carbon fiber side of composites as my day job is working with fiberglass and wet laying so i thought i would give carbon fiber a go and was wondering a couple of things i was thinking of making a leather wallett wrapped in carbon fiber what carbon fiber and epoxy resin keeps it soft so you can fold it etc? Also if i make moulds off of plugs with polyester resin and 450 csm can i make epoxy carbon fiber parts off of the moulds the epoxy resin wont mess with the polyester mould? Cheers Darren
