ABSTRACT:
A fabric assembly particularly useful as soft body armor has two separate sections each containing a number of fabrics made from yarns having a tenacity of at least 7.3 grams per dtex and a modulus of at least 100 grams per dtex. Compressed fabrics in the first section are employed and are connected by connectors that have a force to break in tension not greater than 65 N and are spaced apart by between 6 to 51 mm. Fabrics in the second section have at most a small amount of compression and are not joined other than to prevent slippage of the fabrics relative to one another.
