This video highlights the high temperature stability of CNT yarns compared to copper wire by applying a 1430 C butane torch to both materials. The copper wire lasts about 5 seconds before melting, while the CNT yarn survives the torch for more than 30 seconds without any visible damage. The high thermal stability and superior […]

Abstract: The above video demonstrates how carbon nanotube fibers are integrated into a spacesuit to help spacesuits mitigate dust contamination for future lunar and Mars missions.The spacesuit fabrication and testing was performed by researchers from the University of North Dakota, Boeing, and the NASA Glenn Research Center. CNT fibers were produced by DexMat. Spacesuit dust […]
Above is a video demonstrating the performance of a badminton racket that uses strings made solely out of CNT yarn! The racket is strung with 700 micron diameter braided CNT yarn from DexMat.
This is no ordinary badminton racket! The strings are made entirely out of DexMat CNT yarn, offering superior performance, durability, and the ability to embed sensors and electronics directly into the rackets of the future because these CNT strings have high electrical conductivity. 700 micron diameter braided CNT yarn was used for the strings on […]
Abstract: NASA is challenged to find ways of effectively shielding sensitive electronic equipment from electromagnetic interference (EMI) without adding significant weight to space flight vehicles and satellites (the heavier they are the more fuel they need to achieve orbit). EMI shielding for wire and cables is an attractive opportunity for weight reduction. However, with the advent […]
Abstract: Electric wires and cables constitute by far the largest weight portion of aircraft electrical power systems, as well as a large fraction of the entire aircraft weight. For example, a modern transport aircraft contains over 200 miles of wire, and an F-22 aircraft has about 20 miles of wiring. The increased emphasis and reliance […]
Abstract: This SBIR Phase I project strives to reduce aircraft wire weight in order to improve aircraft range and reduce operating costs. Commercial and military aerospace companies are heavily concerned with fuel costs associated with aircraft operation, as this expense contributes significantly to the total costs of the company. Substantial reductions in aircraft weight could […]
Abstract: In an era of reduced Defense budgets and increasing threats, military planners are seeking new technologies to reduce operating costs and increase operation capabilities for space and aviation platforms, and weight reduction is an attractive target. For example, transportation costs to geosynchronous orbits using a NASA reusable launch vehicle are close to $10,000 per […]
