Abstract
The invention discloses an embedded wave-absorption composite material structure. The embedded wave-absorption composite material structure comprises a wave transmission carrier structure, adhesive films (2), metamaterial metal micro-structures (4) and a lower-layer carbon fiber carrying structure (5), wherein the outer surface of the lower-layer carbon fiber carrying structure (5) is polished and roughened. The wave transmission carrier structure comprises an upper-layer wave transmission carrier structure (1) and a middle-layer wave transmission carrier structure (3), wherein the upper-layer wave transmission carrier structure (1) is connected with the middle-layer wave transmission carrier structure (3) through the first adhesive film (2), the metamaterial metal micro-structures (4) are placed into the middle-layer wave transmission carrier structure (3), and the middle-layer wave transmission carrier structure (3) and the lower-layer carbon fiber carrying structure (5) adhere to each other through the second adhesive film (2). The embedded wave-absorption composite material structure has a good weight reduction effect, and integrates the wave absorption function and the carrying function; due to the fact that the metamaterial metal micro-structures (4) are placed into wave transmission fibers, the wave absorption function is fulfilled through a circuit simulated frequency selective surface, and the requirement for invisibility of the new generation of planes can be well met.
Description
Technical field
The present invention relates to one and insert type Wave suction composite material structure, particularly one is using carbon fibre composite as supporting part, and Meta Materials metal micro structure is as the Wave suction composite material structure with stealthy function integrating " inhaling ripple-carrying " of inhaling ripple portion.
Background technology
Composite material such as carbon fiber/epoxy and carbon fiber/span have been widely used in the fuselage of fighter plane and fighter plane, main wing, the vertical fin wing, the position such as the horizontal tail wing and covering, serve good loss of weight effect, substantially increase the antifatigue of body, the performance such as corrosion-resistant.Stealth is the important technology requirement that opportunity of combat of new generation proposes, although composite material can play good weight loss effect, but can not meet the requirement of opportunity of combat stealth of new generation.Realize stealthy function at present often to adopt in two ways, one is structure stealthy (as sawtooth covering), and another kind is achieved by exterior trim invisible coating.By the limited efficiency that structure is stealthy, and add the manufacture difficulty of composite material, and exterior trim invisible coating has formidable shortcoming in implementing process and effect, as the THICKNESS CONTROL of layer and the cohesive force of layer and body weak etc.
Meta Materials is a kind of artificial electromagnetic material, for tiny metal micro structure tissue, realize inhaling wave energy by the technology (this technology is founded by American scholar B.A.Munk and research partner thereof) of breadboardin frequency-selective surfaces, the stealthy demand of aircraft of new generation can be met well.The resistivity of glass fibre and Kevlar fiber is high, be good electromagnetic wave transparent material, but the stretch modulus of fiber own is lower, but high-performance carbon fibre composite material is the strong reflector of radar energy, can not realize stealthy function.High performance carbon fiber needs to combine with other Meta Materials reducing RCS (RCS) object that just can reach and reduce RCS (RCS).
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one to integrate the Wave suction composite material structure with stealthy function of " inhaling ripple-carrying ", inhale ripple by Meta Materials metal micro structure, the stealthy demand of aircraft of new generation can be met well.
The object of the invention is to be achieved through the following technical solutions: one inserts type Wave suction composite material structure, it comprises wave transparent carrier structure, glued membrane, Meta Materials metal micro structure and outer surface pass through lower floor's carbon fiber bearing structure of polishing alligatoring, described wave transparent carrier structure comprises upper strata wave transparent carrier structure and middle level wave transparent carrier structure, upper strata wave transparent carrier structure is connected with middle level wave transparent carrier structure by glued membrane, Meta Materials metal micro structure has been inserted in the wave transparent carrier structure of middle level, middle level wave transparent carrier structure is bonding by glued membrane with lower floor carbon fiber bearing structure.
Described wave transparent carrier structure is at least formed by two-layer wave prepreg laying and the thickness of wave transparent carrier structure is less than or equal to 1mm.
Described wave prepreg is one or more the combination in quartz fibre, glass fibre and Kevlar fiber.
Described lower floor's carbon fiber bearing structure at least forms by one deck is carbon-fiber-reinforced.
The invention has the beneficial effects as follows: lighter in weight of the present invention that there is good loss of weight effect; The present invention simultaneously integrates " inhaling ripple-carrying ", and Meta Materials metal micro structure is inserted in wave fiber (quartz fibre, glass fibre), realize inhaling wave energy by breadboardin frequency-selective surfaces, the stealthy requirement of aircraft of new generation can be met well.
