Book excerpt: All-carbon composites are carbon materials reinforced with other carbon materials, typically nanostructures such as carbon nanofibers or nanotubes. There are a large number of all-carbon materials, many of which demonstrate unique and useful sets of properties. Combining and hybridising different carbon materials and nanomaterials together also opens up a number of possibilities to fine-tune the materials for desirable combinations of these properties. All-carbon Composites and Hybrids provides a broad overview of these materials including discussions of synthesis, characterisation and the applications of a wide variety of all-carbon composite materials. This will be a useful volume for any researchers interested in carbon and nanotechnology.
