Core Viewpoint - The article discusses the unique characteristics and advanced technology behind civil aviation tires, which are crucial for supporting the weight of large aircraft and enduring high-speed takeoffs and landings. Group 1: Structure and Functionality - Civil aviation tires are designed with a complex structure consisting of approximately 17 layers, including protective layers and airtight layers, enabling them to withstand extreme conditions [3][7]. - For example, the Boeing 747-8 has a maximum takeoff weight of about 440 tons, while its tire diameter ranges from 1.1 to 1.6 meters, showcasing the tire's ability to support a massive aircraft [1][5]. Group 2: Material Composition - High-standard rubber is essential for manufacturing civil aviation tires, which must maintain flexibility at low temperatures and strength at high temperatures, along with high impact resistance and wear resistance [4][8]. - Natural rubber, primarily sourced from Southeast Asian countries, has been a key component, but recent advancements in synthetic rubber technology have been made in China [4][8]. Group 3: Technological Advancements - Significant breakthroughs in civil aviation tire technology have been achieved in China, including the development of biomimetic synthetic rubber that matches the performance of imported premium natural rubber [4][8]. - A new large-scale civil aviation tire production line is set to be operational in November 2024 in Guilin, Guangxi, capable of producing 100,000 high-performance tires annually, utilizing Industry 4.0 standards for automation and intelligence [9]. Group 4: Future Outlook - With ongoing technological advancements, China's self-sufficiency in civil aviation tire production is expected to improve, enhancing the safety and stability of civil aviation transportation [5][9].
