#composites, #sustainability, #carbonfootprint, #renewableenergy, #fibers, #resins Last week I wrote about the raw materials for composites and how high their carbon footprint is, primarily because at present most if not all raw materials for advanced composites are based in petroleum – big oil.  This week I want to follow the roadmap outlined in my new book to the next step.  That step is the production process for the fibers and resins that make up modern composites, that i
