BALLISTIC RESISTANT BODY ARMOR ARTICLES

摘要

The present invention relates to body armor articles for resisting ballistic objects. The articles comprise woven fab-ric 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 re-peating 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.
