<p>The present invention relates to body armor articles for resisting ballistic objects. The articles comprise unidirectional fabric layers (12) and sheet layers (14). The unidirectional fabric layers (12) are made from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex. The sheet layers (14) comprise non-woven random oriented fibrous sheets and/or non-fibrous films. The unidirectional fabric layers (12) and the sheet layers (14) are stacked together comprising a first core section (22) which includes at least two repeating units of, in order, at least one of the unidirectional fabric layers (12) then at least one of the sheet layers (14). The sheet layers (14) comprise 0.5 to 30 wt % of the total weight of the article.</p> |
