Embodiment 1

[0029] Example one, as attached figure 1 As shown, the preparation process of the flexible bulletproof and stab-resistant structure of the present invention has a mass proportion of 75% polycarbonate, a mass proportion of 20% glass fiber, and a certain amount of flame retardant, toughening agent, color particles and other auxiliary components ( The content is 5%) after mixing and stirring, put into the injection molding machine 1. Among them, flame retardants, tougheners, color particles and other additives play a role in improving the performance and appearance of protective materials. Two sets of symmetrical injection molds 2 that can be injection-processed at the same time are provided on the opposite side of the injection molding machine 1 in the left and right directions, and then a base cloth 3 is laid between the symmetrical injection molds 2. The base cloth 3 is in a long strip shape, one end is wound on the shrink tube 4, the other end extends downward, and then tensio...

Embodiment 2

[0032] In the second embodiment, the preparation process of the flexible bullet-proof and stab-proof structure of the present invention has a mass proportion of 65% nylon 66 and 35% carbon fiber short fibers after being mixed and stirred, and then placed in the injection molding machine 1. Two sets of symmetrical injection molds 2 that can be injection-processed at the same time are provided on the opposite side of the injection molding machine 1 in the left and right directions, and then a base cloth 3 is laid between the symmetrical injection molds 2. The base fabric is a long strip, one end is wound on the shrink tube 4, the other end extends downward, and then tensioned by the transmission mechanism 5. The base fabric is a fabric made of carbon fiber aramid with a weight range of 200 grams / M2, the thickness is 0.15mm, making the material lighter on the basis of ensuring strength. After that, the injection molding machine is started, and the above-mentioned composite materi...

Abstract

The invention relates to a preparing technology for a flexible bullet-proof and piercing-proof structure. The preparing technology specifically comprises the following preparing steps that firstly, a protection composite particle material is prepared; secondly, base cloth is laid between two sets of injection molds of an injection molding machine, the protection composite particle material is arranged on the two sides of the base cloth in an injection molding manner through the injection molds at the same time, the protection composite particle material is subjected to hot melting, seeps into a base cloth layer and then is cured to form a two-face protection material layer, mold opening is conducted, after the base cloth of an injection molding part is downwards transmitted, the base cloth is tensioned, and then injection molding is conducted; and thirdly, a flexible gap is machined. The structure of the product prepared through the preparing technology has excellent bullet-proof and piercing-proof performance and also has improved flexibility performance. A thermoplastic material and an enhanced material composite material are arranged on the adopted base cloth in an injection molding manner, the thermoplastic material and the enhanced material composite material are subjected to hot melting, seep into the base cloth layer and then are cured to form the two-face protection material layer, gaps among particles of the thermoplastic material and the enhanced material composite material can be eliminated, and the structure is compact and has more excellent bullet-proof and piercing-proof performance; and in addition, the preparing technology is simple, and the production efficiency is high.

Description

Technical field [0001] The invention relates to a preparation process, in particular to a preparation process of a flexible bulletproof and stab-proof structure, which is applied to the technical field of human life safety protection composite materials. Background technique [0002] Body armor is a kind of equipment that can absorb and dissipate the energy of the warhead, prevent penetration, reduce blunt injuries, and effectively protect the body's protective parts. The stab-resistant clothing is a kind of clothing that can effectively protect the human body from attacks by common sharps such as daggers from various angles and reduce the threat of stab wounds on the protective parts of the human body. They are the protective equipment that public security officers and security personnel must wear when performing dangerous tasks to protect the main organs of public security officers and security personnel from damage caused by common offensive weapons such as bullets and daggers...
