Embodiment 1

[0045] Embodiment 1: Take a flat mold and coat the surface with a 0.01mm thick release agent. First, a 2mm thick surface durable layer is prepared by a conventional vacuum-assisted molding process, and one side is polished to remove residues; Take a number of ceramic sheets with a size of 50mm×50mm×10mm and a rough surface. Rinse them with acetone. Also bonded with an adhesive, the thickness of the ceramic layer is 10mm. After bonding, brush a layer of adhesive on the ceramic surface. The adhesive is epoxy-polyamide adhesive, and a rigid backplane layer is laid. The rigid backplane layer is made of 27 layers of carbon fiber cloth, and then a layer of high-permeability medium layer is laid in turn. , As the composite material of the isolation layer, the composite material is also prepared in advance by vacuum assisted forming process, and then the bulletproof functional layer is laid. The bulletproof functional layer is formed by overlapping 50 layers of aramid fiber cloth, and...

Embodiment 2

[0046] Embodiment 2: Take a special-shaped mold, coat it with a 0.03mm thick release agent, and then lay a rigid backplane layer, a high-permeability medium layer, an isolation layer, a bulletproof functional layer, and a release cloth in sequence from bottom to top A layer of high-permeability medium layer is laid on the upper surface of the release cloth. The rigid backsheet layer 3 is made of overlapping layers of 17 layers of high-strength glass fiber cloth; the isolation layer 4 is made of conventional rubber sheets, and the bulletproof functional layer is made of 30 layers of PBO. The fiber cloth is laid overlappingly; a layer of release cloth and a high-permeability medium layer are laid on it, and a spiral tube vacuum line is laid on the side of the multi-layer material laid above, and there is a glue injection on the same side of the high-permeability medium layer Put a ring of sealant on the periphery of the special-shaped mold, and cover the vacuum bag film. Except f...

Abstract

A bullet-resistant material is composed of bullet-resistant layer and reinforcing transition layer. Its preparing process includes such steps as spreading high-osmos medium on the surface of said both layers, making a resin-filling port, arranging the spiral vacuumizing tubular wire on mould, loading said both layers and mould in a film case, sealing it, vacuumizing to suck the resin by said layers via said resin-filling port, pressing, solidifying and demoulding.

Description

technical field [0001] The patent of the present invention relates to a bulletproof material and its forming method, in particular to a bulletproof material with an irregular shape and integral solidification of a multi-layer structure and its forming method, which are mainly used in tanks, armored vehicles and turrets with bulletproof function requirements, Tail box and bulletproof car body and other equipment fields. technical background [0002] The traditional molding method of bulletproof materials mostly adopts the step-by-step molding method, and each layer of material is molded separately, and then bonded together with an adhesive. Among them, the composite material layer is prepared by a molding process. The forming process of this process is complicated, the cost is high, and the production efficiency is low. It belongs to open mold forming, which pollutes the environment, and it is difficult to complete the molding process for complex components with irregular sha...
