Carbon roving refers to a bundle of continuous carbon fibers that are gathered together to form a single strand or "rovings." Carbon fibers are lightweight and extremely strong fibers composed primarily of carbon atoms. They are known for their high tensile strength, low weight, and resistance to heat and chemicals. In the case of carbon roving, numerous carbon fibers are collected and twisted or bundled together without being woven into a fabric or cloth.

The individual fibers are typically aligned parallel to each other within the roving. This bundling process provides structural integrity and facilitates handling and processing of the carbon fibers. Carbon roving is commonly used in composite material applications, particularly in the manufacturing of carbon fiber reinforced plastics (CFRP). CFRP is a composite material where carbon fibers are embedded in a matrix, often made of epoxy resin, to create a strong and lightweight structure.

The carbon roving serves as the reinforcement element in the composite, providing the tensile strength and stiffness required for structural applications. Carbon roving is utilized in various industries, including aerospace, automotive, wind energy, sports equipment, and marine. It is used to produce a wide range of components such as aircraft wings, automotive body panels, wind turbine blades, sporting goods, and boat hulls. The size and properties of carbon roving can vary depending on the intended application. Different diameters and fiber counts are available to suit specific requirements.

The roving can be further processed, such as by impregnating it with resin or weaving it into fabric, to create different forms of carbon fiber composites. In summary, carbon roving consists of bundled carbon fibers and serves as a reinforcement element in the production of carbon fiber composites. Its high strength and lightweight characteristics make it a valuable material in industries that demand strong, durable, and lightweight structures.
