Multi-cell soft material structure filled with shear thickening fluid, multi-cell soft laminated protection structure filled with shear thickening fluid and preparation method of multi-cell soft material structure filled with shear thickening fluid and multi-cell soft laminated protection structure filled with shear thickening fluid

Abstract

The invention discloses a laminated protection structure design including a multi-cell soft material filled with shear thickening fluid and a multi-cell hard surface layer and a preparation method thereof. In the process that the structure is subjected to an impact load, the impact strength effect of the hard surface layer and the shear thickening fluid can effectively resist impact penetration, impact damage to a unit cell of the hard surface layer cannot be transmitted to other hard cells, and it can be ensured that the overall structure bears and resists the impact effect twice or multiple times at different cell position points; meanwhile, under the action of the impact load, deformation of the multi-cell soft material structure, moving of the overall hard multi-cell surface layer along with the soft body layer, and flow of the shear thickening fluid can effectively consume the impact energy, and the aftereffect injury to the human body caused by the impact effect is avoided; and the overall structural form can effectively resist the impact effect, and certain flexibility is ensured.

Description

technical field [0001] The invention relates to the technical field of protective products, in particular to a multicellular soft material filled with a shear thickening liquid, a laminated protective structure and a preparation method. Background technique [0002] With the improvement of the demand for human safety protection in the emergency response process such as anti-terrorism and explosion protection, new requirements are also put forward for the structure and performance of human protective equipment. Though the body protective equipment of existing structural form can realize the protection of gunshot and puncture to a certain extent, still there are many weak points. Most of the traditional body protective equipment in the form of hard structure is relatively heavy, and the main protection area is relatively hard, which will affect the mobility of the wearer to a certain extent. The disadvantage of purely rigid body protective equipment is that even if it can eff...
