Description

An interior panel with electromagnetic masking function

technical field

The utility model belongs to the technical field of aircraft electromagnetic protection, in particular to an interior trim panel with the function of electromagnetic shielding.

Background technique

At present, most of the interior panels of aircraft adopt honeycomb sandwich structure. The composite material of honeycomb sandwich structure is composed of panel (skin) and core material. The core material is often made of hexagonal aramid paper honeycomb material, and the panel is usually made of glass fiber reinforced Phenolic or epoxy prepregs. For some aircraft working in a specific high electromagnetic radiation environment, in order to isolate the electromagnetic radiation outside the aircraft, it is usually necessary to set up a separate electromagnetic shielding cabin inside the aircraft to protect the occupants and isolate the electromagnetic waves outside the aircraft from affecting the inside of the aircraft. Interference with electronic equipment. Since the functions of the electromagnetic shielding cabin and the interior of the aircraft partially overlap, this increases the overall weight of the aircraft and forms an additional burden. Moreover, the space in the cabin of the aircraft itself is small, and adding a shielded cabin will further compress the available space.

Utility model content

The purpose of the utility model is to design an interior panel with electromagnetic shielding function in the aircraft cabin, which integrates multiple functions, realizes the electromagnetic shielding function of the interior panel, and achieves the purpose of weight reduction and effective use of space.

The technical scheme of the utility model: an interior trim panel with electromagnetic masking function, including: inner skin, adhesive film, honeycomb core, outer skin;

Both sides of the honeycomb core are provided with an inner skin and an outer skin, and the inner skin and the outer skin are connected with the honeycomb core through an adhesive film; the inner skin and the outer skin are made of continuous long-fiber nickel-plated fiber composite material.

Preferably, the surfaces of the inner skin and the outer skin are respectively provided with Tetra membranes.

The utility model has the advantages of utilizing the conductive properties of traditional composite materials to realize the electromagnetic shielding function, simple structure, cost saving, and completing the electromagnetic protection in the aircraft cabin through the interior decoration structure, so as to achieve the purpose of weight reduction and effective use of space.
