Shear thickening fluid protective armor device wrapped with high-performance fiber cloth

Abstract

The invention provides a shear thickening fluid protective armor device wrapped with high-performance fiber cloth. The shear thickening fluid protective armor device wrapped with the high-performance fiber cloth comprises the outer high-performance fiber cloth layer and the inner high-performance fiber cloth layer. The outer high-performance fiber cloth layer and the inner high-performance fiber cloth layer are processed into a row of continuous structures with semi-columnar spaces through allocation. Semi-columnar plastic containers filled with shear thickening fluid are arranged in the semi-columnar spaces. Compared with the mode of increasing the thickness of the section of a building body structure, the shear thickening fluid protective armor device wrapped with the high-performance fiber cloth has a better effect in preventing impact of flying matter, and is free of modifying layout of the body structure too much.

Description

technical field [0001] The invention relates to the design of building structure protection technology with special protection requirements in the field of civil engineering, in particular to a high-performance fiber cloth-wrapped shear thickening liquid protective armor. Background technique [0002] Terrorist activities are becoming more and more rampant in today's world, especially since the 9.11 incident, how to deal with terrorist organizations using commercial aircraft and other large projectiles to attack important buildings (such as nuclear power plants, commercial center buildings, etc.) Infringement has become an important and urgent subject that all countries are scrambling to study. For example, after the 9.11 incident, for the new nuclear power plants in the United States, the US Nuclear Regulatory Commission (NRC) clearly required that the design should take into account the impact of large commercial aircraft, and also conducted a special assessment of the nuc...

Problems solved by technology

[0004] In order to deal with the threat of large missiles, traditional methods such as increasing the cross-sectional size of the main structure are generally used in the structural design of new buildings, and the existing buildings are generally reinforced by enlarging the cross-section reinforcement method, external steel reinforcement method, and bonded steel reinforcement method. methods, these methods have certain application value in the engineering field, and because the focus of these methods is to increase the rigidity of the structure, the effect of resisting high-speed impact is not good, and there are complex construction techniques, difficult guarantee of project quality, construction and maintenance costs Insufficient high

[0005] According to the novelty search results conducted by the inventor, there is no technical solution to improve the impact resistance of important buildings by using external high-performance fiber cloth to wrap shear thickening fluid protective armor.
