First Claim
1. A body armor article for resisting ballistic objects, comprising:
- a plurality of woven fabric layers woven from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex;
a plurality of sheet layers comprising non-woven random oriented fibrous sheets and/or non fibrous films, each of the sheet layers having a thickness of at least 0.013 mm;
the woven fabric layers and the sheet layers 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;
whereini. the sheet layers comprise 0.5 to 30 wt % of the total weight of the article.ii. each of the sheet layers has an average acoustic velocity at least 600 m/sec.iii. the sheet layers are isotropic or substantially isotropic.iv. the woven fabric layers and the sheet layers are attached together at 10% or less of their surface areas.

Abstract
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 non-woven random oriented fibrous sheets and/or non fibrous films. 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.
