US12435955 - Flexible armor

A flexible armor is described herein that includes a first and second layer of fiber weave material, an inner ceramic layer, and a sheer thickening fluid. The first layer of fiber weave material forms an outermost layer on one side of the flexible armor. The second layer of fiber weave material forms an outmost layer opposite the first layer of fiber weave material on the other side of the flexible armor. The inner ceramic layer is a single continuous piece of interlinked ceramic material that is formed in between the first layer of fiber weave material and the second layer of fiber weave material. The first layer of fiber weave material, the second layer of fiber weave material, the inner ceramic layer, or a combination thereof is coated in the shear thickening fluid and the shear thickening fluid fills open space within each layer.
