‘Liquid armor’ based on shear-thickening non-Newtonian fluids


Speaking broadly, non-Newtonian fluids are of two types: Either they get thinner under shear, or they get thicker. Shear-thickening fluids, like the common corn flour-water mixture sometimes called “oobleck,” obviously, get thicker when a force is applied. This new and highly secretive non-Newtonian fluid formulation by British defense giant BAE is like oobleck to the power of ten, and can, reportedly, be very effectively combined with Kevlar to improve human body armor performance against bullets.

  1. Cornflour may be:

    * Cornmeal, flour ground from dried corn
    * Cornstarch, the white, powdered starch of the maize grain (in UK usage, cornflour normally has this particular meaning)
    * Masa, the flour of hominy
    * Wheat starch, in Australia
