Description

Technical Field

[0001] This article belongs to the technical field of composite plug-in plate pressing and fixing, and specifically relates to a pressing and fixing device for composite protective plug-in plates. Background Art

[0002] Currently, there are two types of high-grade non-metallic protective plates produced domestically: 1) those made from a single pressed aramid or high-strength, high-modulus polyethylene (PE) ballistic material; and 2) those made from aramid or high-strength, high-modulus polyethylene (PE) ballistic material pressed and then bonded to a ballistic ceramic plate. Both types of plates are used in conjunction with body armor and are considered complementary protection.

[0003] At present, PE ceramic composite protective inserts need to be bonded together by several ceramic sheets in order to adapt to the curvature of various protective inserts. After being hit by external forces or shot, the ceramic will loosen and fall off on a large scale. After disassembly and analysis, it is found that the bonding between PE and ceramic is not only affected by the performance of the adhesive. After the glue is applied to the ceramic, the subsequent pressing method also has a great influence on the bonding strength between the ceramic and PE board.

[0004] Most of the existing pressing methods are simply to complete the bonding and then use a clamp to fix the plate at multiple points, so that the PE plate and the ceramic plate can increase the time of close bonding, thereby ensuring the fastening effect after the glue is bonded. However, only fixing with a clamp cannot ensure that every area of ​​the bonding surface is fully stressed, and the clamp will also cause uneven force, resulting in uneven thickness of the glue layer, resulting in a decrease in the bonding effect. In addition, due to the form of the clamp, a special pressing device is needed to better improve the bonding strength between ceramics and PE plates, making production and use more convenient.
