The generalized honeycomb core lattice includes hexagonal honeycomb core stability angle, diamond, rectangle and sine curve. It is high, easy to manufacture and widely used. Its structure description parameters are mainly:; Side length, wall thickness, honeycomb height and evenness. The honeycomb core is divided into aluminum honeycomb core Glass cloth Honeycomb core, aramid paper honeycomb core, etc. Due to different materials, their performance characteristics are also different. Aluminum honeycomb core: good mechanical performance, durability, heat conduction, but complicated carbon fibre compound material When the panel is in direct contact, there will be electrochemical corrosion. In addition to being used as sandwich structure core, it is also used as I-related heat exchange electrical equipment. Aramid paper honeycomb core: light weight, high enough compression and shear strength, good fatigue strength, dielectric property and electromagnetic wave transmission performance, high cost. Glass cloth honeycomb core has excellent electrical insulation performance and electromagnetic wave transmission performance. Compared with aramid paper honeycomb core, it has large capacity but low cost. The honeycomb structure core has very high strength and rigidity, and is widely used in modern shipbuilding, aviation and aerospace industries
