• Precursor Preparation: As mentioned earlier, for PAN-based carbon fiber roving, the production starts with the polymerization of acrylonitrile monomers to form a PAN polymer. This polymer is then processed into filaments through spinning techniques.

• Oxidation: The PAN filaments are oxidized in air at a relatively low temperature (around 200 - 300°C) to convert the organic structure into a more thermally stable ladder-like structure, preventing the filaments from melting during the subsequent carbonization process.

• Carbonization: The oxidized filaments are then heated in an inert atmosphere (such as nitrogen) at high temperatures (1000 - 1500°C) to remove non-carbon elements (such as hydrogen, oxygen, and nitrogen), leaving behind carbon-rich fibers.

• Surface Treatment and Sizing: To improve the adhesion between the carbon fibers and the matrix materials (such as resins) in composite applications, the carbon fibers may undergo surface treatment. A sizing agent is then applied to protect the fibers from damage during handling and further enhance their compatibility with the matrix.

• Roving Formation: The individual carbon fibers are grouped together to form the roving, which can be wound onto bobbins or spools for storage and transportation.

• High Tensile Strength: Carbon fiber roving has an extremely high tensile strength, often exceeding 3,000 MPa, which is much higher than that of traditional materials like steel. This makes it capable of withstanding significant pulling forces without breaking, making it ideal for applications where strength is a critical factor.

• Low Density: With a density of around 1.7 - 1.9 g/cm³, which is about one-fourth that of steel, carbon fiber roving is very lightweight. This property enables the production of lightweight yet strong components, reducing the overall weight of structures and products.

• High Modulus of Elasticity: It has a high modulus of elasticity, meaning it can resist deformation under stress and return to its original shape once the stress is removed. This characteristic is important for maintaining the structural integrity of components.

it can make body, doors, roof and other parts, which can reduce the weight of the body, improve the acceleration performance, braking performance and fuel economy of the car, and also improve the stability and safety of the car.

Carbon Fiber Plain Weave Fabric can also be used to manufacture sports equipment, such as golf clubs, tennis rackets, bicycle frames, etc. Sports equipment made of plain carbon fiber cloth can have higher strength and better vibration absorption properties, improving athlete performance and comfort.

>> Other Applications

include shipbuilding, building materials, electronic products, etc. In these areas, plain carbon fiber cloth can play a role in strengthening, weight reduction, heat insulation and so on.

Prevent carbon fiber Fabric 

From being exposed to sunlight for a long time. Long exposure to sunlight will make the surface of carbon fiber Fabric crack and fade, affecting the beauty and service life.

When storing carbon fiber Fabric

Attention should be paid to avoid humidity, high temperature and other environments. When storing carbon fiber Fabric, avoid humidity, high temperature and other environments, and keep dry and ventilated.
