Design of Low Cost, Highly Adsorbent Activated Carbon Fibers
Abstract
U.S. troops and civilians face increasing risk of exposure to chemical and biological threats as developing nations and terrorist groups turn to these lower cost weapons for their arsenals. EKOS has developed a novel activated carbon fiber - (ACF) that combines the low cost and durability of GAC with tailored pore size and pore surface chemistry for improved defense against chemical agents. ACF has another key advantage as it can be manufactured in a wide variety of product forms that allows for design flexibility (hoods, masks, parkas, handkerchiefs). In addition, EKOS demonstrated the potential to utilize carbon coated sub-micron glass fibers to replace both components of the current gas mask (HEPA filter and bed of GAC) to greatly reduce pressure drop and achieve filtration/adsorption in a single step. Finally, designed structures obtained through computational fluid dynamics were built through stereolithography (honeycomb and octet truss) then coated with activated carbon to examine a unique strategy for next generation gas masks.
