Hexagonal honeycomb is a building structure in which bees use the smallest beeswax to achieve maximum capacity. Inspired by it, mankind creatively invented various honeycomb core composite structures and products. In the field of applied materials, the honeycomb core composite material is similar to the continuously arranged I-steel structure, and is known for its excellent compression, bending and ultra-light structural characteristics. Compared with the same type of solid materials, the strength-to-weight ratio and rigidity-to-weight ratio of honeycomb materials are the highest.

      From a mechanical point of view, the closed hexagonal honeycomb structure can use the least material to obtain the maximum force. When subjected to a load perpendicular to the board surface, the bending stiffness is almost the same as that of a solid sheet, but the weight is 70-90% lighter, and it is not easy to deform, crack or break, and has shock absorption, sound insulation, heat insulation and strong weather resistance. Features. The special hexagonal structure and characteristics of the honeycomb core make the honeycomb material widely used in high-tech fields such as aviation and aerospace.

        With the rapid development of modern aviation technology, advanced honeycomb core composite materials meet the current requirements of high performance and light weight for aircraft with high specific strength, high specific modulus and low expansion coefficient. Therefore, honeycomb core composite materials have become the fourth largest aerospace structural material that has rapidly emerged after aluminum, steel, and titanium. At present, the wing, tail, rudder, fuselage skin, aircraft floor and other components produced by major aircraft companies in the world are all made of honeycomb core composite material structure. In addition to the extensive use of honeycomb core composite materials in aircraft, they are also widely used in fields such as high-speed railways, high-end automobiles, submarines, and civil building materials.

       The characteristics of the honeycomb core composite material and its superior designability enable it to be used in more fields, and the proportion of use will also increase.
