Another widely used ballistic fiber is Honeywell’s Spectra. Pound-for-pound, Spectra is 10 times stronger than steel, yet light enough to float. Spectra fiber applications include cut protection, ropes, vehicular and personal armor, and fishing line, as well as various specialty applications.
Like Kevlar and Twaron, Spectra is also being combined with other materials to create fabrics that benefit from the performance characteristics of each fiber. For example, Spectra is one of the key components of Spectra Shield composite fabrics. Spectra Shield technology lays parallel strands of these synthetic fibers side by side and holds them in place with a resin system, creating a unidirectional tape. Two layers are then cross-plied at right angles and fused into a composite structure under heat and pressure. The cross-plied material is then packaged as rolls, ready for shipping to ballistic vest manufacturers.[PAGEBREAK]Vest Innovations
Beyond lighter, tougher, and softer fiber formulations, vest manufacturers are pursuing new designs and new technologies for making their products more comfortable without sacrificing protection.
One of the companies leading the way in this market is Safariland. Now an Armor Holdings company, Safariland has been developing equipment for law enforcement safety for decades, including a varied line of high-quality body armor.
Safariland says its latest vest, the ZERO-G, was designed for increased safety, comfort, and wearability. The ZERO-G looks different and feels different because it is different. Its shape offers enhanced ballistic coverage and the carrier has been simplified for better comfort. To create the ZERO-G, Safariland collected biometric data from hundreds of male and female armor wearers and then put it through careful analysis. The result is a vest with more than 600 unique panel shapes designed to fit virtually any body type. By applying biometrics to panel design Safariland dramatically improved officer arm, shoulder, and upper torso movement.
