    • The present invention relates to body armor articles for resisting ballistic objects. The articles comprise woven fabric layers and sheet layers. The woven fabric layers 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 comprise nonwoven random oriented fibrous sheets, each of the sheet layers comprising a uniform mixture of 3 to 60 weight percent polymeric binder and 40 to 97 weight percent non-fibrillated fibers. The woven fabric layers and the sheet layers are stacked together comprising a first core section which includes at least two repeating units of, in order, at least one of the woven fabric layers then at least one of the sheet layers. The sheet layers comprise 0.5 to 30 wt % of the total weight of the article.
