The present disclosure relates to a system and method for characterizing an impact in a fabric. The system may include a sensing element woven in the fabric wherein a parameter of the sensing element depends on a strain in the sensing element; a transducer coupled to the sensing element wherein the transducer is configured to generate an output based on the parameter of the sensing element; and a controller coupled to the transducer, the controller configured to receive the output of the transducer, to determine a strain in the sensing element based, at least in part, on a change in the output of the transducer, and to characterize the impact in the fabric based on the strain in the sensing element.

Techniques to measure strain development and failure in a fabric

A momentum trap ballistic armor comprises an accelerating layer, a plug layer adjacent to the accelerating layer, and an energy absorbing layer. The plug layer includes an opening and at least one plug maintained within the opening. When a projectile impacts the accelerating layer, the plug is accelerated to the velocity of the projectile before the projectile perforates the plug, forming a projectile-plug combination. The energy absorbing layer is used to capture the projectile-plug combination. The accelerating layer is typically ceramic, the plug layer is typically metal, and the energy absorbing layer is typically ballistic cloth material.

A momentum trap ballistic armor system comprises an accelerating layer and a plug layer adjacent to the a accelerating layer. The plug layer includes an opening and at least one plug maintained within the opening. When a projectile impacts the accelerating layer, the plug is accelerated to the velocity of the projectile before the projectile perforates the plug, forming a projectile-plug combination. Typically, the accelerating layer and plug layer are joined with an energy absorbing layer, which is used to capture a projectile-plug combination. The accelerating layer is typically ceramic, the plug layer is typically metal, and the energy absorbing layer is typically ballistic cloth material.
