Honeycomb materials originated from bionics and were first used in aerospace, which is a super lightweight composite material that developed for the special needs of aerospace science and technology. Today, honeycomb materials are widely used in aircraft, rockets and spaceships.
The honeycomb sandwich structure is usually made of thin panels and thicker honeycomb core. Because of its advantages such as light weight, high bending rigidity and high strength, sound absorption, sound insulation and good insulation performance. In the developed countries, honeycomb sandwich composite material has been successfully used in the primary and secondary bearing structure of aircraft, such as wing, fuselage, tail, flooring, interior parts, etc. The design and manufacturing process of honeycomb sandwich structure composite material is one of the key technologies for advanced aircraft development.
