Embodiment 1

[0027] Installation of PE bulletproof plate: use 20mm thick PE bulletproof plate 4 as the bulletproof material, drill holes around the PE bulletproof plate 4 at a distance of 200mm, the hole diameter is 5mm, and then bond the same size 0.5mm thick on the back of the PE bulletproof plate 4 The surface of the aluminum plate 6 is bonded to the panel 1 with the same size and thickness of 0.3 mm; pressed for 2 hours at a temperature of 60°C, cooled naturally for 4 hours, and directly riveted on the equipment with rivets.

[0028] see figure 1 , the repair method of PE bulletproof plate, the steps are as follows:

[0029] (1), cutting of PE bulletproof plate 4: adopt hand-held cutting machine to cut panel 1 and PE bulletproof plate 4 in the PE bulletproof plate area of ​​bulge from panel 1 side, adopt stopper during cutting, in order to avoid damaging aluminum plate 6; Limit the cutting depth to 19mm, cut out a square hole of 300mm×300mm centered on the bulge area, and remove the d...

Embodiment 2

[0035] Installation of PE bulletproof plate: use 24mm thick PE bulletproof plate 4 as the bulletproof material, drill holes around the PE bulletproof plate 4 at a distance of 200mm, the hole diameter is 5mm, and then bond the same size 0.7mm thick on the back of the PE bulletproof plate 4 The surface of the aluminum plate 6 is bonded to the panel 1 with the same size and thickness of 0.5 mm; pressed for 2 hours at a temperature of 60°C, cooled naturally for 4 hours, and directly riveted on the equipment with rivets.

[0036] The repair method of PE bulletproof plate, the steps are as follows:

[0037] (1) Cutting of PE bulletproof plate: Use a hole opener with a diameter of 300mm to cut the panel 1 and PE bulletproof plate 4 in the bulging PE bulletproof plate area from the side of panel 1, and limit the cutting depth to 23mm. As the center, cut out a round hole with a diameter of 300mm, and remove the damaged panel 1 and PE bulletproof plate 4; use a stopper when cutting to a...

Abstract

The invention discloses a repairing method of a PE (Poly Ethylene) armor plate. The repairing method of the PE armor plate comprises the steps of after removing an original damaged panel and an original damaged PE armor plate, polishing an aluminum plate surface; installing a PE armor plate for repairing as a PE armor plate filling block on an aluminum plate by adopting a bonding and riveting way, and bonding a panel on the outer surface of the PE armor plate; and finally adopting a repairing adhesive for filling and leveling up a gap. According to the repairing method of the PE armor plate provided by the invention, the replacement of the whole PE armor plate can be avoided, the repaired PE armor plate maintains an original performance, the repairing cost is low, the operation can be carried out simply, convenient and feasibly, and the use cost of the PE armor plate is greatly reduced.

Description

technical field [0001] The invention relates to a bulletproof repair method, in particular to a repair method for a PE bulletproof plate. Background technique [0002] Military vehicles often use steel plates and ceramic plates as bulletproof materials. The density of steel plates and ceramics is high, which seriously affects the mobility of vehicles. With the development of polymer materials, new high-performance materials have emerged. Among them, ultra-high molecular weight polyethylene (PE) fibers have the characteristics of light weight and high strength, and their density is only 1g / cm 3 , the strength reaches 3.3GPa, and the PE ballistic board made of this fiber has good ballistic performance. [0003] PE bulletproof plates can be used as bulletproof armor, bulletproof inserts, etc. After being shot, the PE bulletproof plate will be delaminated and bulged. For example, a 20mm thick PE bulletproof plate is designed 100 meters away from a 7.62 ordinary bullet type 53 r...
