Use of Three-dimensional Angle-interlock Woven Fabric for Seamless Female Body Armor: Part II: Mathematical Modeling

Abstract

Angle-interlock woven fabric off the potential to make female body armor as it can form integrally the required dome shape without cutting or molding because of its extraordinary moldability. In Part I of this paper, ballistic impact testing proved that the angle interlock fabrics provide no less ballistic performance than other commercially used fabrics according to the National Institute of Justice (NIJ) standard. Based on the extraordinary moldability and the satisfactory ballistic performance, Part II presents a mathematical model to determine the pattern geometry for the front panel of female body armor. The raised bust area was divided into seven different parts for the modeling, using the simplest surfaces possible. This mathematical model takes the body size and bra size as the input, and the output is the profile of the front pattern of the female body armor. This work enables the speedy creation of the front pattern of female body armor, and more importantly a novel approach for making seamless female body armor with satisfactory ballistic performance.
