In August 2014, Dr. Drelich visited the Military Institute of Engineering (MIE) in Rio de Janeiro (Brazil) and established a research collaboration with this institute in the area of natural fibers, composite materials, diamonds and alloys. The first paper entitled Unlocking Function of Aramid Fibers in Multilayered Ballistic Armor and published in Metallurgical and Materials Transactions A (Vol. 46A, No. 1, 2015, pp. 37-40) is the result of this MIE – MTU collaboration. In this report, prepared by researchers from MIE and co-authored by Dr. Drelich, it is shown for the first time that, in addition to already reported fabric rupture, debonding, and stretching, a massive incrustation of ceramic fragments onto the fabric fibers is responsible for the high ballistic performance of the multilayered armor system component.
