Title:
MULTIFUNCTIONAL STEALTH FLEXIBLE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/029198
Kind Code:
A1
Abstract:
A multifunctional stealth flexible material and a preparation method therefor. The material is obtained by compositing an electromagnetic wave loss layer and an infrared stealth layer on a fabric subjected to plasma treatment and having a visible light stealth function and then compositing a non-woven fabric on a functional surface. The electromagnetic wave loss layer is of a vertical structure which is formed of a chopped fibrous electromagnetic wave absorbing material (a mixture of activated carbon fibers and nickel-plated carbon fibers according to a mass ratio of 1:(2-10)) in an electrostatic flocking manner; the infrared stealth layer is obtained by adding a microcapsule-coated phase change material into a water-based polyurethane adhesive and then performing coating, loading and drying. The fibrous electromagnetic wave absorbing material forms, in an electrostatic flocking manner, the electromagnetic wave loss layer having a vertical structure, and is like a wedge structure material, so that on one hand, electromagnetic waves can easily enter the material for loss absorption, and on the other hand, multiple reflection loss can be enhanced. Then a paraffin phase change material is used as an infrared stealth material, so that the prepared fabric not only has a visible light stealth function, but also has infrared and radar stealth functions.
