Problems solved by technology

Stealth bulletproof materials have dual functions of radar stealth and bulletproof, but the previous stealth bulletproof materials are mainly composed of radar absorbing materials and bulletproof materials with separate functions, so their thickness is relatively thick and their surface density is high, which is difficult to meet the requirements of today's weapons and equipment. Thin thickness and light weight requirements for stealth bulletproof materials

Abstract

The invention discloses a wave-absorbing invisible bulletproof plate of an integrated structure and a preparation method of the wave-absorbing invisible bulletproof plate. The invisible bulletproof plate sequentially comprises a glass fiber reinforced plastic plate layer, an invisible bulletproof layer and a carbon fiber composite material layer from outside to inside; the invisible bulletproof layer is obtained by alternately laminating fiber reinforced composite material layers and wave-absorbing material layers; composite materials in the fiber reinforced composite material layers are ultra-high molecular weight polyethylene fiber reinforced polyethylene-based composite materials or aramid fiber epoxy resin-based composite materials; and the thickness of the invisible bulletproof plateis smaller than or equal to 23 mm. The preparation method comprises the following steps that the fiber reinforced material layers and the wave-absorbing material layers are alternately laminated to form the invisible bulletproof layer, then the invisible bulletproof layer, the glass fiber reinforced plastic plate layer and the carbon fiber composite material layer are adhered, the adhered invisible bulletproof plate is pressed, and the edge is sealed to obtain the wave-absorbing invisible bulletproof plate. The prepared integrated invisible bulletproof plate is light in weight and small in thickness, can resist rifle shooting, has excellent wave-absorbing performance, and is simple in preparation method.

Description

technical field [0001] The invention belongs to the technical field of stealth and bulletproof, and in particular relates to a broadband and high-efficiency wave-absorbing stealth bulletproof plate with an integrated structure and a preparation method thereof. Background technique [0002] With the rapid development of military science and technology in today's world, the reconnaissance and strike capabilities have also been developed rapidly. In order to improve the battlefield survivability of weapons and equipment, stealth bulletproof materials have emerged as the times require. Stealth bulletproof materials have dual functions of radar stealth and bulletproof, but the previous stealth bulletproof materials are mainly composed of radar absorbing materials and bulletproof materials with separate functions, so their thickness is relatively thick and their surface density is high, which is difficult to meet the requirements of today's weapons and equipment. Thin thickness an...
