Abstract

The invention belongs to the technical field of an armored protecting material and relates to a human body protecting material technology, in particular to an anti-puncturing compound material. High strength and high modulus of aramid fiber plain cloth and high hardness of modified vinyl ester resin are utilized to resist the puncturing of a cutting tool. The aramid fiber reinforced resin based anti-puncturing compound material provided by the invention has an n-layer superposed structure of modified vinyl ester resin impregnated aramid fiber fabric sheet, wherein n is a natural number from 12-100; the surface density of the superposed structure is 4440-19000g / m<2>; the structure strength and hardness are high; the anti-puncturing property is excellent; the weight is light; the designability is strong; a shellproof effect is achieved; and the compound material is suitable for the field of human body protection and armoring protection.

Description

technical field [0001] The invention belongs to the technical field of armor protection materials, relates to the technology of human body protection materials, and particularly relates to a stab-resistant composite material. Background technique [0002] In the field of human protection, in addition to bulletproof requirements, it is also necessary to have protective functions for various knives, so it is necessary to use materials that have effective protective functions for various knives to design protective clothing. [0003] Materials with effective protection function for knives include metal plates, including steel plates, aluminum plates, titanium alloy plates and other metal alloy plates. [0004] Due to the large weight of the metal alloy plate, it is not easy to deform, and the wearing comfort is poor. The United States also invented a metal scale stab-proof material similar to fish scales, which has good conformability and significantly improved wearing comfort...
