The company and Tongji University, Shanghai Aircraft Manufacturing Company and other units jointly undertake the “Application Research of Aramid Honeycomb Paper in my country’s Large Passenger Aircraft” project of the Ministry of Science and Technology. This project is a national key basic material technology improvement and industrialization project.

    The development of large passenger aircraft is a major national strategy. The composite material-aramid honeycomb sandwich structure is the main material for large passenger aircraft, and its dosage has become one of the important symbols to measure the advanced nature of the aircraft. At present, the aramid honeycomb paper used in the large passenger aircraft developed in my country all rely on imports. The project focuses on the major demand for the localization of lightweight composite sandwich structures in the development of large passenger aircraft, and focuses on key scientific issues such as identification and optimization of process parameters in the manufacture of aramid honeycomb paper, aramid honeycomb cores and honeycomb sandwich structures, so as to improve the domestic production of aramid honeycombs. The performance and stability of aramid honeycomb paper and honeycomb core, and the design and manufacturing method system of low-defect and high-performance domestic honeycomb sandwich structure for large passenger aircraft, and realize the domestic aramid honeycomb paper that meets airworthiness requirements in the tail rudder of large passenger aircraft. Validation of applications for surfaces and cabin floors.

    The project has significant economic, social and environmental benefits, and can provide strong scientific and technological support for the successful development of my country’s large passenger aircraft and the enhancement of international competitiveness.
