Abstract

A transparent composite armor is made of tens to hundreds or even thousands of thin layers of material each with a thickness of 10-500 μm. An appropriate amount of impedance mismatch between the layers causes some reflection at each interface but limit the amplitude of the resulting tensile wave below the tensile strength of the constituent materials. The result is an improvement in ballistic performance and that will result is a significant impact in reducing size, weight, and volume of the armor.
