Pitch-based carbon fiber is a carbon fiber material made from petroleum asphalt or coal tar asphalt. It is characterized by abundant raw materials, low cost, high carbonization rate, and low product cost. High-performance pitch-based carbon fiber has outstanding tensile modulus and excellent conductivity, making it suitable for use as a […]

The production process for PAN-based carbon fibers is as follows: polymerization of the precursor solution—spinning—preoxidation—carbonization—graphitization—surface treatment. Specifically: Polypropylene monomers are polymerized to form the spinning solution, which is then spun into fibers. The finished raw fibers are reacted in a multi-stage oxidation furnace under an air atmosphere to produce pre-oxidized

Structural Characteristics of Polyacrylonitrile-Based Carbon Fibers   Polyacrylonitrile (PAN)-based carbon fibers are a type of inorganic fiber material with a carbon content of over 90%, appearing black in color. The diameter of the fibers varies depending on their specific performance requirements. PAN-based carbon fibers exhibit a hybrid structure comprising both

Throat Liner Ablation-resistant Carbon-carbon Composites Products   In the field of weaponry, the throat liner is a critical high-temperature component in various types of rocket projectiles. During its service life, it must withstand temperatures of approximately 3,000°C, internal gas pressures exceeding 15 MPa, and high-speed, high-temperature gas erosion. Traditional high-silica
