Abstract

Shear thickening materials are a class of materials whose viscosity increases with the increase of shear rate. This study takes the non-Newtonian fluid corn starch aqueous solution as an example, focuses on the research of the solvent system of shear thickening materials, selects solvents that can improve material performance, and optimizes the proportioning of shear thickening materials through orthogonal tests. The optimal proportioning scheme is determined as follows: corn starch: solvent = 45:55, where the solvent consists of ethyl oleate: butyl acetate: ethanol: amyl acetate = 45:15:15:25. Through impact resistance tests, the maximum impact energy per unit area that the shear thickening material can withstand is found to be 4.64×10⁶ J/m². Through protection performance tests, it is determined that when the thickness of the shear thickening material is 3 mm, the effect of protecting glass bottles is optimal, and it can be applied in production and daily life.
