The invention discloses a detachable composite armor structure and belongs to the technical field of composite materials, the detachable composite armor structure is formed by splicing a plurality of module units, each module unit is of a
layered structure and sequentially comprises a supporting layer, a buffering anti-bullet layer, a core anti-bullet layer and a
broadband wave absorbing and composite anti-bullet layer from inside to outside, the thickness of each module unit is smaller than or equal to 75 mm, and the surface density of each module unit is smaller than or equal to 90 kg / m; the
broadband wave-absorbing and composite anti-elastic layer comprises more than two wave-transparent anti-elastic
layers and
broadband wave-absorbing
layers which are arranged in a staggered manner, and the outmost layer is the wave-transparent anti-elastic layer; the number of the core anti-bullet
layers is two, and the two core anti-bullet layers are detachably connected, so that the core anti-bullet layers are conveniently and rapidly detached and replaced. The device is installed on the outer surface of the
armored car, and the low surface density meets the lightweight design requirement; the wave-transparent anti-bullet layer of the double-
sine wave structure can transmit electromagnetic
waves,
resist bullet or fragment
impact and change bullet tracks, and the broadband wave-absorbing layer absorbs broadband electromagnetic
waves. The middle core anti-bullet layer and the buffer anti-bullet layer can
resist the bullet and buffer the bullet, and the damaged outer layer can be replaced quickly.
