Ballistic Properties of Barium Titanate Army Aircraft Structures

Abstract

Ballistic tests were conducted to determine the ballistic resistance of a barium titanate piezoelectric material with and without a polarizing voltage. It was hypothesized that the polarizing voltage increases ballistic resistance. The tests were designed to use thicknesses insufficient to stop a round but sufficient to determine effectiveness of polarization. Based on limited tests, the barium titanate with a polarizing voltage was 31 percent and 45 percent more resistant to penetration by .30 caliber ball and armor-piercing projectiles, respectively, at impact velocities of 2000 fps, the polarizing voltage had no effect.
