Advantages of Carbon Fiber Pre-oxidized Fiber Yarns:
High-Temperature Resistance
Stable long-term operation in air at 200–300°C, with short-term tolerance exceeding 400°C—outperforming most synthetic fibers.
Can be further carbonized in inert atmospheres to produce carbon fiber, enabling high-temperature conversion.
Flame Retardancy
Limiting Oxygen Index (LOI) of 40–60% (classified as non-combustible); non-dripping and self-extinguishing when removed from flame.
Chemical Stability
Resists corrosion from acids, alkalis, and organic solvents; ideal for harsh chemical environments.
Mechanical Properties
Strength and modulus intermediate between PAN precursor and carbon fiber; superior flexibility to carbon fiber, facilitating textile processing (e.g., weaving, winding).
Lightweight
Density: 1.4–1.6 g/cm³ (lower than metals), optimal for weight-sensitive applications.
Process Compatibility
Directly usable in composite preforms or further processed into carbon fiber via carbonization/graphitization.
Primary Application Fields:
Firefighting Gear: Flame-resistant suits, heat-resistant gloves, escape blankets.
Industrial Insulation: High-temperature pipe wrapping, molten metal barriers, welding blankets.
Aerospace: Aircraft cabin flame-retardant textiles, auxiliary materials for engine thermal barriers.
Used in prepregs or resin composites to manufacture heat-resistant, flame-retardant components (e.g., electronics housings, chemical tank linings).
Enhances heat/wear resistance in brake pads and friction materials.
Converted into carbon fiber via carbonization, applied in aerospace, wind turbine blades, and automotive lightweighting.
High-temperature flue gas filtration (e.g., power plants, cement factories); chemical-resistant filter bags.
Battery separator materials (e.g., Li-ion batteries), leveraging thermal stability and insulation.
Fuel cell gas diffusion layer substrates.
High-temperature gaskets, clutch linings — combining flexibility with thermal stability.
Antistatic protective wear, EM-shielding fabrics (via post-metallization treatment).
