Abstract

The invention discloses a flexible stab-resistant material and a preparation method thereof. The flexible stab-resistant material is composed of small protection modules and high-strength connecting members connecting the small protection modules. The high-strength connecting members are arranged among the small protection modules according to a certain order. The small protection modules are made from thermoplastic high molecular materials and high-property reinforced fiber in a combined mode, such as glass fibers, aramid fibers, chopped fibers of carbon fibers, nylon, and polycarbonate. The high-strength connecting members are made from high-strength high-modulus polyethylene, filaments, yarns or strands, and the filaments, the yarns or the strands are made from aramid fibers or carbon fiber materials. Gaps are formed among the small protection modules, so that the flexibility of the protection material is greatly improved. The invention further discloses a preparation method for forming the flexible stab-resistant material in an injection mode.

Description

technical field [0001] The invention relates to a flexible anti-stab material and a preparation method thereof, in particular to a flexible anti-stab material with excellent anti-stab performance and a preparation method thereof. Background technique [0002] In recent years, terrorist attacks have continued to occur in various countries, and personnel from various countries have stepped up research and development in the field of security protection. In our country, with the development of social economy and the improvement of people's awareness of safety protection, the demand for safety protection equipment is increasing. The fourth key development area in the "Twelfth Five-Year Plan for Industrial Textiles" specifically mentions the development of flexible stab-resistant and cut-resistant fabrics, so the development of safety protection materials is in line with the development direction of the national textile industry, and flexible stab-resistant materials are used as ...
