▎ 摘  要

NOVELTY - The structure has a sandwich structure filled with a wave-absorbing material, where the wave-absorbing material is flocculent or fiber-graphene or carbon nano-tube wave-absorbing material. The sandwich structure is provided with a core material and an outer layer panel and an inner layer panel. The outer layer panel and the inner layer panel are arranged at two sides of the core material, where the outer layer panel is made of heat-proof, wave-transmitting fiber reinforced resin-based composite material or fiber reinforced ceramic-based composite material, the core material of the sandwich structure is honeycomb core or triangular pyramid structure, the inner layer panel of the sandwich structure is made of carbon fiber resin-based composite material. An edge of a structure body is selected as a pressing plate area formed by bonding the outer layer panel and the inner layer panel. USE - Light anti-heat bearing invisible integrated structure for an aircraft body. ADVANTAGE - The structure effectively reduces problems of structural overlap and increased demand space caused by separate design of each function, and improves available space in an inner side of the aircraft. The structure has less weight, low cost, high mass efficiency, strength, integrity and rigidity, and satisfies load design requirements. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a light anti-heat bearing invisible integrated structure for an aircraft body.
