Protective Woven Fabric

Technology: Fabric architectures to improve the performance, survivability, damage tolerance, and dynamic energy absorption of woven fiber in a broad array of applications

Opportunity: Available for licensing, with the potential for collaboration/joint development with Navy researchers. This opportunity is furnished through TechLink, a partnership intermediary.

Details: The Navy’s technology applies crimp imbalanced (CI) fibers to help woven materials better protect against ballistics, punctures, and wear. The technology absorbs dynamic energy 20% better than current commercially available fibers, providing an additional layer of defense without adding weight that slows down performance.

Both single-ply CI layers and crimp-imbalanced gradients (CIG) consisting of multiple layers of stacked woven fabrics incorporating CI and crimp balanced (CB) fibers demonstrate improved performance and damage tolerance by increasing the number of active fibers and extending the engagement time of those fibers to reduce fiber failures during dynamic loading events. CIG architectures provide both ballistic and puncture protection, and can enhance composite resistance to fatigue failures.The simple modified woven architecture uses inexpensive techniques compatible with existing weaving processes to produce a very comfortable fabric with excellent flexibility and drapability characteristics.

Applications: Improved dynamic energy absorption and stress-wave mitigation capabilities can improve a wide array of dry fabric and composite applications ranging from composite structures in vehicles, aircraft, boats, and wind turbines to body armor and other personal protective products.
