Abstract
An armor composite material has been invented which contains a fabric which has been impregnated with shear thickening fluid. This invention offers a ballistic resistant material that is more flexible and less bulky than comparable, conventional ballistic fabric. The material in the alternative can be puncture resistant. The invented material offers superior ballistic performance and/or puncture resistance compared to conventional ballistic fabric-based materials of equal thickness. The invented material can be applied to applications requiring armor that is compact and/or flexible, such as body armor, protective clothing and flexible protective devices and shields, and stab resistant clothing and devices.
Claims18
A process of preventing an object to penetrate a person or structure which comprises covering said person or said structure with a material so that at least part of said person or at least part of said structure is covered with said material and subjecting said material to an object to so that
- said person or said structure is moving,
- said object is moving or
- both said object and said person or said structure is moving
- so that the object partially penetrates said material and wherein said material comprises a fabric or a yarn which further comprises a shear thickening fluid (STF) intercalated into said fabric and/or yarn wherein said STF remains in a fluid form and said STF comprises particles suspended in a solvent and said particle-solvent suspension remains in a flowable form after intercalation and said solvent is environmentally stable and remains integral to said material and said suspended particles during service.
