PAN-based carbon fibers and composites have become the ideal materials for aviation application

and structure dosage and application locations are the important symbols of aircraft. Development status of domestic PANbased carbon fiber was summarized. Main problems of domestic PAN-based carbon fiber were pointed out from eight aspects

including industry distribution

product quality

supporting equipment

industry chain

etc. Then

the key problems during aviation evaluation and application were discussed. At last

development suggestion was presented in order to promote sustainable development of domestic PAN-based carbon fiber.
