Referring to the main civilian application market for high grade carbon fiber and its composites in the future, Wei Huazhen said. On the one hand, we should seize the application of high-end civil fields such as rail transit, automobiles, etc. On the other hand, we should seize the application in civil aviation, such as civil aircraft, small aircraft, UAV and other fields. 。

For domestic carbon fiber and its composites, how to further grasp the opportunity to live in the field of military industry, Wei Huazhen said that taking army equipment as an example, lightweight is becoming more and more critical for army equipment. The army is equipped with a large variety of equipment and a large quantity of equipment. The annual order quantity of a single model is dozens of units and even hundreds of units. The annual order quantity of armored weapons is hundreds or even thousands of years, and dozens of models are produced every year. "The weaponry industry will be the largest demand market for military products of China's carbon fiber, and it can effectively guide the localization of high grade carbon fiber." Wei Huazhen said.
