Carbon Nanofiber Bridge “Lights Up” SAMPE Conference
University of Dayton (UD) engineering students recently fabricated and tested their “HOT-SPAN” model bridge containing an electrically conductive road surface. A 110-volt, alternating current was applied to the ends of the bridge to demonstrate the ability to light up a 75-watt light bulb and heat the road surface for winter time de-icing. The bridge was comprised entirely of glass fiber composite materials, with the exception of carbon nanofibers that were incorporated into the fiber glass road surface, termed “NANO-Sphalt”.
