| Abstract Scope |
Carbon-carbon composites, originally developed for aerospace applications, are materials that consist of a carbonaceous matrix with an embedded carbon filler providing the required reinforcement for thermal and mechanical stability. This work characterizes a carbon-carbon composites from the nano- to the micron-scale with a variety of analytical techniques. Both graphitizing and non-graphitizing matrices are evaluated with three variations of graphene: 300-800 nm reduced graphene oxide, 1-2 um graphene nano-platelets and 2-5 µm graphene. The carbon-carbon composite so formed is then characterized at different length scales to understand the graphene additives’ influence on the composites’ observable macroscopic properties. The interaction is also addressed using polarized light microscopy and scanning and transmission electron microscopy. Interfacial nanostructure is shown to determine graphitization potential. |
