Abstract

The invention discloses a nano-composite gel matrix multi-layer fabric stab-resistant composite material and a preparation method thereof. The preparation method comprises the following steps of dissolving polyether F127 diacrylate in a solvent, performing stirring for at least 12 hours, adding hydroxyapatite nanoparticles under the stirring condition, adjusting the temperature to 0-10 DEG C, adding a monomer, an initiator and an accelerant, introducing nitrogen for at least 15 minutes to carry out nitrogen bubbling to obtain nano-composite hydrogel, stacking a plurality of layers of aramid fabrics impregnated with the nano-composite hydrogel together, and performing standing in a vacuum environment for at least 24 hours to obtain the nano-composite gel matrix multi-layer fabric stab-resistant composite material. After the stab-resistant material formed by combining the nano-composite hydrogel and the fabrics is damaged, the damage of fibers cannot be recovered, and the hydrogel in the fabrics can be partially self-repaired, so that the self-healed nano-composite gel matrix multi-layer fabric stab-resistant composite material still has a certain stab-resistant effect.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a nanocomposite gel matrix multilayer fabric stab-proof composite material and a preparation method thereof. Background technique [0002] Stab-resistant materials are mainly divided into hard, semi-rigid and soft materials. Rigid composite materials increase the risk of injury due to poor flexibility and comfort. Because stab-resistant materials are more in line with current needs, scholars at home and abroad pay more and more attention to the research of stab-resistant materials. Currently, there are three approaches to improve the stab resistance of soft materials: one is to weave high-count, high-density high-performance yarns and then stack them by lamination or needling. The other is to compound the fabric with resin, and fill the gaps between the interweaving points of the fabric with resin to increase the friction between the yarns and improve its ...
