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

Since its emergence in 1958, carbon-carbon composite materials have attracted widespread attention worldwide due to their outstanding performance. Many industrialized countries have invested significant human, material, and financial resources into the research and development of this material, continuously improving its performance and expanding its application scope. Over the past few

Cost Reduction   Carbon-carbon composites are often referred to as “black gold.” The high cost of carbon fiber and the lengthy densification process are the primary factors contributing to the high cost of carbon-carbon composites.   Production costs have always been the primary factor limiting the development of carbon fiber.

Isostatic graphite, renowned for its high strength, excellent thermal conductivity, and superior corrosion resistance, is widely used in high-end industries such as photovoltaics, semiconductors, and nuclear energy. However, issues such as sintering cracks and uneven impregnation during production have long been technical challenges within the industry. Statistics show that the
