Abstract

The invention relates to a novel bulletproof structure and a manufacturing process. The novel bulletproof structure comprises a base and an upper cover plate, wherein the base comprises a honeycomb cavity and a shear thickening fluid with which the honeycomb cavity is filled; fiber cloth is laid on the honeycomb cavity; a reinforcing plate is placed on the fiber cloth; and the upper cover plate and the reinforcing plate are bonded and fixed together. According to the novel bulletproof structure, the energy absorption and energy consumption characteristics of the shear thickening fluid are fully utilized, so that an obvious bulletproof effect is achieved under impact of low-speed bullets. The bulletproof performance of a composite material is further enhanced through a honeycomb structure and the reinforcing plate laid on the fiber cloth.

Description

technical field [0001] The invention relates to the technical field of bulletproof protective products, in particular to a novel bulletproof structure and a manufacturing process. Background technique [0002] Traditional body protective equipment is composed of hard or semi-rigid materials, which will restrict the movement of the human body, have poor comfort, and cannot provide full-body protection. In order to solve this problem, the shear thickening liquid is combined with high-performance fiber fabrics to prepare soft protective materials. Composites are prepared mainly by impregnating high-performance fabrics with shear-thickening fluids. First, dilute the high-concentration shear thickening solution with ethanol to ensure uniform impregnation of the fabric. The diluted solution impregnates the fabric by rolling, and then puts the fabric in an oven and heats it to volatilize the ethanol. The shear thickened fluid composites were prepared. The protection mechanism is...
