Material for ballistic protection, method of preparation and use thereof

The present invention provides a material for ballistic protection, characterized in that it comprises: - a plurality of compact layers of ballistic fiber and - between the layers of ballistic fibers inserted at least one intermediate layer of non- Newtonian fluid exhibiting an increase in viscosity resulting from an increase in shear stress, optionally containing particles having the size of from 1 to 700 nm or antiplasticizing agents, said intermediate layer being placed either directly between layers of ballistic fiber, or placed between the layers on a packing or a perforated packing or applied on a fabric. The invention further provides a method of preparation of said material. This material is flexible and has a low weight and can be used in particular for bulletproof vests, combat helmets, personal body armor and/or for shielding light infantry and passenger automobiles.
