Problems solved by technology

The former is very easy to cause the overall fragmentation of the ceramic plate after being impacted by bullets, thus affecting the bulletproof effect; while the bulletproof insert prepared by the latter is partially weak due to the gaps between the ceramic sheets. When the bulletproof insert is impacted by bullets, it is easy to penetrating the bullet

Abstract

The invention discloses a bulletproof flashboard and a preparation method and an application thereof. The preparation method of the bulletproof flashboard comprises the following steps of: bonding a protective layer, a ceramic layer, a middle layer, a supporting layer and a buffer layer which are coated with bonding agents in sequence; coating an outermost layer with a coating layer which is coated with a bonding agent; and molding under the negative pressure and curing. Due to the adoption of a novel structural design for the bulletproof flashboard, the entire bulletproof flashboard can effective resist the impact of bullets continuously shot by a light weapon without being broken. Moreover, the bulletproof flashboard has the characteristics of light weight, high bullet resistance, easiness in processing and the like.

Description

technical field [0001] The invention relates to a composite bulletproof board and its preparation method and application. Background technique [0002] In terms of the antagonism of war, bulletproof equipment is an inevitable product that accompanies bullet weapons. At present, conventional weapons are developing rapidly, and the threat level to individual soldiers is gradually increasing. In order to improve the bulletproof survivability and battlefield mobility of individual soldiers, it is necessary to develop a lightweight and efficient bulletproof composite material system. [0003] Bulletproof inserts are an important part of body armor and are used to improve the protection level of body armor. At present, the composite method of bulletproof inserts is mostly made by directly bonding the whole ceramic plate and the high-performance fiber fabric laminate through an adhesive, or directly bonding small pieces of spliced ​​ceramics to the fiber fabric laminate. The form...
