Abstract:

In response to environmental concerns regarding nylon decelerators from sonobuoys polluting the oceans and negatively impacting a wide variety of ocean life, a multi-agency proposal was presented to ESTCP to replace the nylon with a biodegradable material. Two materials studied were polyvinyl alcohol PVOH and polyhydroxyalkanoate PHA. Single and multilayered PVOH films were evaluated as well as a coarse composite weave of PVOHPHA film strips and a weave of PHA film strips. A suitable replacement material was not quite matured to the readiness point for technology transition.
