Solid flat carbon, like solid round carbon rods, are made of unidirectionally-oriented carbon fibers and resin and are extremely linearly strong. Also known as flat graphite bars, flat carbon rods bend easily on the flat side and are rigid on the narrow side, making them a great support or strengthening rod for any applications for which a flat, rather than round, profile is preferable. These flat composite bars are available in a wide variety of widths and thicknesses. If you are interested in custom lengths or custom machining, please contact us at info@goodwinds.com or 206-632-6151 to speak to a composites engineer.
