Abstract
A lightweight armor system providing blast protection and ballistic protection against small arms fire, suitable for use in helmets, personnel or vehicle protection, and other armor systems. A hard substrate is coated on the front surface with a thin elastomeric polymer layer, in which hollow ceramic or metal spheres are encapsulated. The coating layer having a thin elastomeric polymer layer with encapsulated metal or ceramic hollow spheres can be stand-alone blast protection, or can be added to an underlying structure. The glass transition temperature of the polymer is preferably between negative fifty Celsius and zero Celsius.
