Dissipative properties of non-Newtonian fluid under impact load

Abstract eng:
The authors investigated the impact resistance of an energy absorber based on non-Newtonian fluid. To fabricate the material, polypropylene glycol and colloidal silica powder 14 ÎĽm in diameter were used. Impact tests were conducted first on a gravity drop test and, after selecting proper mixture proportions, on an electromagnetic hammer. During the final research phase ballistic tests were conducted of composites the back layer of which consisted of shear thickening fluid enclosed in honeycomb shaped cells. The front layer of the composite consisted of aramid fabric in thermoplastic polymer matrix laminate. The composite was shot at with 9x19 mm Parabellum ammunition in order to assess dynamic deflection.
