Abstract
The objective of this program was to define the transient behavior of the felt and the force interaction between it and the projectile. Six felt samples (nylon (3), orlon, dacron, polypropylene) were tested using the 17- grain fragment simulating projectile at various velocities up to and greater than the ballistic limit velocity. Graphical differentiation was used to obtain velocity-time, force-time, and force-distance relationships. Qualitative evaluations reveal that strength, elongation, and transverse wave velocity are the three predominant parameters in determining effectiveness. The energy absorbed by a felt is maximum at the ballistic limit velocity and decreases dramatically at higher (complete perforation) velocities. An analytical model based upon momentum considerations is compared to the experimental results.Keywords
