Embodiment Construction

[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] The flexible bulletproof composite material of the present invention is composed of high-strength filament fiber material (the main carrier of the projectile shock wave) and a matrix composed of resin 1 and resin 2 (the dispersion of the projectile shock wave). The high-strength filament fiber material is the main carrier of the projectile shock wave, which can consume most of the projectile shock function through its own fracture. The role of the matrix is ​​to disperse the shock wave of the projectile, so that the shock wave propagates in the largest area, so as to mobilize more fibers to bear the shock wave, and reduce the fiber breakage caused by the repea...

Abstract

The invention discloses a flexible bulletproof compound material with a novel resin matrix, which is formed by compounding filament fibers with matrix resin, wherein the matrix resin is aqueous polyacrylate; by adopting the compound material processed by the novel matrix resin, no pollution is generated in the whole production process of molding, the ageing resistance and the yellowing resistance are good, and the decrease of the bulletproof performance is slight at higher temperature. Further, the matrix resin also comprises polyolefin which exists on the surface of the compound material in the manner of thin film, and thereby, the bulletproof performance of the compound material can be improved. Further, the filament fibers are of a special molded structure, so that the bulletproof performance of the compound material can also be improved. The invention also discloses a processing method for the flexible bulletproof compound material, which comprises the following steps: infiltrating the filament fibers with the aqueous polyacrylate when the structure is molded or after the structure is molded to form a preimpregnated sheet; then, coating a polyolefin thin film onto the formed preimpregnated sheet; and performing hot-pressing compound molding. The processing method is low in cost and has high processing efficiency.

Description

technical field [0001] The invention relates to the field of bulletproof materials, in particular to a flexible bulletproof composite material with a novel resin matrix and a processing method thereof. The composite material is suitable for protective materials such as soft and hard bulletproof vests, bulletproof helmets and bulletproof armor. Background technique [0002] In the past ten years, soft bulletproof vests with flexible materials as bulletproof layers have gradually replaced hard bulletproof vests with special metal materials as bulletproof layers due to their advantages of small weight, light mobility, and good concealment. At present, flexible bulletproof materials in the world mainly use high-strength fiber fabrics or flexible composite materials. [0003] The fabric structure is easy to form, but its bulletproof performance is low and the cost of raw materials is high; the flexible composite material has high bulletproof performance and low overall raw materi...
