According to the Chinese Academy of Thermal Sciences Rubber Research Institute news on the 26th, using the Academy of Thermal Sciences independent research and development of aviation tires made of natural rubber trial C919, ARJ21 and other models of 24 aircraft tires through the verification of dynamic performance tests, of which 1 model, 2 specifications tires have recently successfully completed the plateau conditions test flight.
Natural rubber is an important industrial raw material and strategic resources, natural rubber molecular weight is the most important factor affecting the quality of natural rubber, but also to determine the tensile strength of natural rubber core indicators. At the same time, natural rubber molecules are also connected at both ends by more than 200 kinds of proteins and more than 10 kinds of phospholipids composed of non-gum components, which interact with each other to form a kind of microscopic network structure, which can not be synthesized by artificial simulation. Therefore, natural rubber in the defense equipment, aviation and maritime and rail transportation and other high-end manufacturing areas with irreplaceable.
Currently, China's aviation tire production using natural rubber raw materials 100% dependent on imports, is the only aviation tire materials have not achieved localization of key materials. In this regard, the Rubber Research Institute of the Chinese Academy of Thermal Sciences, in conjunction with the natural rubber production, processing and application of colleges and universities, research institutes, leading enterprises to carry out the whole industry chain research, preferred "Thermal Research 73397" and other new varieties of rubber trees as a special rubber planting materials for aviation tires, the development and promulgation of the "special rubber plantation production technical specifications". Special rubber plantation production technical specifications" agricultural industry standards, "standardized natural rubber plantation management specifications for aviation tires" enterprise standards, the construction of a standardized demonstration rubber plantation for aviation tires and processing demonstration bases for aviation tires to provide stable, high-quality latex raw materials for the production of aviation tires.
