Our high precision carbon fibre square bar is manufactured to high tolerances and maximum performance using pultruded unidirectional carbon fibres which means that the strength of the bar runs laterally along its length. The smaller diameter bars are easy to bend in longer lengths but offer considerably more stiffness over shorter lengths. The stiffness of the bar increases as the diameter increases, with the larger diameter bars becoming extremely difficult to bend over shorter lengths and offering significant stiffness over longer lengths.

Pultruded carbon fibre bars are used in a wide range of applications requiring a very high strength to weight ratio. They offer excellent mechanical performance as well as very good water and chemical resistance making them suitable for use in harsh environments.

Typical applications include model-making, engineering and automation, robotics and UAVs, recreational and sporting equipment, and even creative uses in art and fashion. If you have a requirement for machined or finished carbon fibre components please ask the Plastock team for more information.
