A REVIEW OF THE DEVELOPMENT OF BALLISTIC NEEDLE-PUNCHED FELTS

摘要: Abstract : As part of the continuing effort to improve ballistic materials for personnel armor, fiber and fabrication parameters, dynamics felt impact, predictive equations attempting connect resistance known measurable parameters were reviewed needle-punched felts. The felts at low areal densities was found be superior that any other material. On hand, increased against higher velocity missiles, become competitive. extent which maintain their superiority moderate is dependent upon certain properties. highest tenacity polyamide fibers are currently best available In case fabrication, a relatively degree needling furnishes general, thicker can tolerated (at same weight density), better resistance. addition, it apparent level protection varies depending method attaining desired thickness. need shown additional work determine effect properties such as denier, molecular weight, distribution, elongation resulting This work, in turn, will depend availability model these studied independently.
