Problems solved by technology

However, this structure fails to maximize the anti-stab performance of the material during the puncture process. When the thickness is low, the anti-stab material only touches the tip of the knife, failing to absorb the anti-stab energy to the greatest extent.

Abstract

The invention discloses a stab-resistant fabric with a porous buffer structure and a preparation method of the stab-resistant fabric, and relates to the field of protective textile materials. The porous buffer structure and the garment fabric are uniformly adhered to the surface of the garment fabric through epoxy resin. A porous buffer structure is obtained through a 3D printing technology; a main body stab-resistant structure is obtained through a 3D printing technology, an injection molding technology or a manual lay-up molding technology; uniformly coating the garment fabric with a layer of epoxy resin, and neatly arranging the porous buffer structures on the garment fabric; coating a layer of epoxy resin on the uniformly arranged porous buffer structures, and integrally arranging the main body puncture-proof structure on the porous buffer structures; the arranged whole stab-resistant fabric is pressurized, cured and shaped on a flat plate hot press, and the stab-resistant fabric with the porous buffer structure is obtained. The weight of the prepared stab-resistant clothes can be reduced, the safety performance of the stab-resistant clothes can be guaranteed, and the requirements of civil and even military fields are met.

Description

technical field [0001] The invention relates to the field of protective textile materials, in particular to a stab-proof fabric with a porous buffer structure and a preparation method thereof. Background technique [0002] It is not only guns and ammunition that threaten people's lives, but also sharp instruments such as knives and daggers. This has led to an increasing demand for stab-resistant ballistic materials. Due to the strict gun control in my country, the protection of high-risk practitioners for sharp instruments is more practical. [0003] The current stab-resistant clothing is mainly divided into hard stab-resistant clothing and soft stab-resistant clothing. Rigid stab-resistant clothing is made of metal armor, high-strength resin (polycarbonate, nylon, etc.) and fiber-reinforced composite materials as the stab-resistant armor. This kind of stab-resistant clothing is heavy and has poor wearing flexibility. Soft stab-resistant clothing is mostly composited wi...
