NI Teijin Shoji Co. Ltd. and an American subsidiary will pay the United States $1.5 million to settle False Claims Act allegations involving the importation and sale of defective Zylon fiber, used as a key ballistic material in bulletproof vests. The U.S. government alleged that the companies were aware that the fiber degraded quickly, rendering the vests containing the Zylon unfit for use. The settlement is apparently part of a larger investigation of the industry’s use of Zylon in body armor. Previous settlements have netted more than $59 million. Teijin has also apparently agreed to cooperate with the ongoing investigation. See FBI Press Release, January 25, 2011.
