Defense Holding's HiPerCon Team to Move Metal Fiber Brush Technology
Arlington, VA (March 9, 2009) – Defense Holdings, Inc® (DHi) and HiPerCon, LLC® have teamed to extend the use of their revolutionary, patented Metal Fiber Brush (MFB) technology from use in U.S. Navy nuclear submarines to other military and commercial applications.
MFBs, which gain their name from the fact that they are constructed of thousands of hair-fine silver alloy fibers running on their tips, offer significant improvement over carbon brushes in both data and current transfer, offering extended brush and slip ring service life, high current capacity, and significant decreases in service acoustic and electrical noise. Our silver alloy fibers offer significantly better service life and higher speeds over gold wire technology at a considerable price advantage. MFB technology was originally developed under the Small Business Independent Research (SBIR) program working with HiPerCon, LLC, the U.S. Navy and the University of Virginia. MFBs are now being backfitted to the Navy’s fleet of nuclear submarines.
Following in the wake of their successes with submarine applications, DHi and HiPerCon adapted their submarine MFBs to solve de-icing system problems for the Navy’s E-2C early warning aircraft and the Air Force’s C-130 aircraft. In these and other aircraft de-icing systems, frequent failures of carbon brushes and the presence of carbon dust can pose significant risk of de-icing system failures and fire. MFBs offer significant reductions in scheduled preventative maintenance providing increased operational availability. DHi can provide the complete spectrum of engineering and life-cycle support for MFBs from a form-fit-function replacement for existing carbon brushes in legacy slip ring systems to complete slip ring design, manufacturing and life cycle support. DHi also offers MFBs for point designs such as its MFB grounding brush. The MFB grounding brush can be easily fitted to existing applications with simple tools and can run on the existing shaft without modifications. DHi’s MFB grounding brush is will clearly outlast existing grounding brush systems and its very low resistance and high current carrying capability ensures protection for your valuable assets. MFB technology is also being applied in a number of products such as consumer electrical devices, wind turbines, vehicle power generation, transportation, and many others.
