Development of Aluminum Honeycomb Panel at Home and Abroad
The world's first honeycomb panel was jointly produced by Posco and Hanlim & C in 1930. By the 1950 s and 1960 s, high-performance honeycomb products had entered a mature stage and were widely used in aviation and aerospace fields. For example, the U.S. Hercules 3 carrier rocket satellite fairing adopts carbon/epoxy panel and aluminum honeycomb structure, Arian 5 adopts a sandwich structure of carbon fiber reinforced plastic panel and aluminum honeycomb core, and the end cap of the Japanese H-2 carrier rocket satellite fairing is an integral forming part made of aluminum alloy, and the cone section and cylinder section both adopt aluminum alloy honeycomb sandwich structure. In addition to aerospace applications, honeycomb aluminum plates are also widely used in railway trains. For example, for STA21 cars made in Japan, brazed honeycomb aluminum plates are only applied to the side walls and roof parts.
