    Main Functions

    Removal of Non-Carbon Elements

    High-temperature pyrolysis removes elements such as O, H, and N from pre-oxidized fibers (residual rate <1%), increasing the carbon content to 92%-99%.

    Formation of Graphite Structure

    High temperatures promote rearrangement of fiber molecular chains, forming a turbostratic graphite structure, which imparts high modulus and high strength to the carbon fibers.

    Key Performance Relationships

    Process control in the carbonization furnace directly affects the tensile modulus (150-900 GPa) and strength (1-7 GPa) of the carbon fibers. It is a crucial element in the development of high-modulus pitch-based carbon fibers (such as M60J grade for aerospace applications).

    Frequently Asked Questions

    How does high-temperature pyrolysis increase carbon content?

    High-temperature pyrolysis effectively removes non-carbon elements like oxygen (O), hydrogen (H), and nitrogen (N) from pre-oxidized fibers, leaving a residual rate of less than 1% and raising the total carbon content to 92%-99%.

    What is a turbostratic graphite structure?

    It is a crystalline structure formed by the rearrangement of fiber molecular chains under high temperatures, which provides the carbon fibers with exceptional strength and high modulus.

    What is the typical tensile modulus and strength of carbon fibers?

    Depending on the process control within the carbonization furnace, the tensile modulus ranges from 150 to 900 GPa, and the tensile strength ranges from 1 to 7 GPa.

    Why is the carbonization furnace critical for carbon fiber production?

    The carbonization furnace allows for precise process control, which directly determines the final mechanical properties, such as tensile strength and modulus, of the carbon fibers.

    Which carbon fiber grade is used for aerospace applications?

    High-modulus pitch-based carbon fibers, such as the M60J grade, are typically developed and utilized for demanding aerospace applications due to their superior performance characteristics.
