Development Situation and Analysis of Advanced PAN-based Carbon Fiber

PAN-based carbon fiber and composite have series of excellent properties, such as low density, high specific strength, high specific modulus, fatigue-resistant, corrosion-resistant, outstanding properties in design, which have become the ideal material for aviation application. First, the development route of advanced PAN-based carbon fiber of Toray Corporation in Japan and Hexcel Corporation in America were summarized. Development trend and latest research of advanced PAN-based carbon fiber were introduced. Meanwhile, the development route of PAN-based carbon fiber of Toray Corporation and Hexcel Corporation were comparison analyzed. Then, based on the development situation of domestic PAN-based carbon fiber, development suggestion of domestic carbon fiber was presented in order to promote sustainable development of domestic carbon fiber.
