BALLISTIC RESISTANCE ENHANCEMENT BY ADJUSTING STRESS WAVE PROPAGATION PATHS
Soft armor for personnel protection is mostly made of layers of fabrics of high performance fibers. Stress wave propagation along the fibers is closely related to the ballistic resistance of the fabric. In this study, the authors adjusted the wave propagation paths and took advantage of the overlapping of the reflective and incident waves. The local stress level in the fiber at the vicinity of the strike point was then reduced temporarily and the time during which the fiber remained its integrity was prolonged. Consequently, the energy absorbed by the fabrics during the whole penetration period was increased. Samples with pre-designed wave propagation paths in fibers were tested against different projectiles. Ballistic resistance was recorded in terms of critical perforation velocity. Significant differences in ballistic resistance were observed from well-controlled samples. These results indicate a significant potential in ballistic performance enhancement by wave propagation path design.
