Carbon Fibres.

Carbon Fibres, Carbon-Polymer Composites and Carbon-Carbon Composites Carbon-Polymer composites consist of carbon fibres, either unidirectional, woven or knitted or 3-Dimensional embedded in a polymer matrix. The polymer matrix can be either a thermosetting resin such as epoxy or a thermoplastic resin such as PEEK. While woven carbon fibre is available un-coated for use in wet lay up manufacturing, the majority of carbon fibre is pre-coated or pre-impregnated (pre-preg) with the polymer. Carbon-carbon composites consist of …
