Example Embodiment

[0045] Example 1: Take a flat mold and coat the surface with a release agent of 0.01mm thickness. First, a 2mm thick surface durable layer is prepared by a conventional vacuum-assisted molding process, and one side is polished to remove residue; Take a number of ceramic pieces with a size of 50mm×50mm×10mm with a rough surface. Wash them with acetone. After drying, arrange the ceramic pieces neatly and bond them to the polished surface of the durable surface layer with an adhesive, between the ceramic pieces Adhesive is also used, and the thickness of the ceramic layer is 10mm. After bonding, the ceramic surface is brushed with a layer of adhesive. The adhesive is epoxy-polyamide adhesive, and the rigid backing layer is laid. The rigid backing layer is made of 27 layers of carbon fiber cloth, and then a layer of high permeability medium layer is laid in sequence , As the composite material of the isolation layer, the composite material is also prepared in advance by the vacuum ass...

Example Embodiment

[0046] Example 2: Take a special-shaped mold, coat it with a release agent with a thickness of 0.03mm, and then place the rigid backing layer, the high permeability medium layer, the isolation layer, the bulletproof functional layer, and the release cloth in order from bottom to top , Lay a layer of high permeability medium on the upper surface of the release cloth. The rigid backplane layer 3 is made up of 17 layers of high-strength fiberglass cloth. The isolation layer 4 is made of conventional rubber sheets, and the bulletproof functional layer is made of 30 layers of PBO. It is made of overlapping fiber cloth; on it, another layer of release cloth and high-permeability medium layer is laid, a spiral tube vacuum line is laid on the side of the above-mentioned laid multi-layer material, and glue is injected on the same side of the high-permeability medium layer Put a circle of sealant on the periphery of the special-shaped mold and cover with a vacuum bag film. Except for the sp...

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...
