THE BALLISTIC AND MECHANICAL PROPERTIES OF POLYMERS

Transparent armor for applications such as vision blocks, wind screens, and face shields rely on polymers either completely or as a part of a ceramic-plastic composite. Transparent polymeric armor systems are not currently as efficient on a weight basis as opaque armor systems. This work was undertaken to find ways to increase the efficiency of polymeric armor systems. It would be highly desirable to be able to correlate ballistic behavior with the material and physical properties of the polymeric system to enable rapid predictions of ballistic resistance as well as to lead to improved transparent armor. Up to the present time no such correlation has been known. It was one of the purposes of this study to determine what properties, if any, would consistently be indicative of the ballistic strength of the polymer. (Author)
