Shear Thickening Fluids (STF) - nanotech “liquid”

admin » 12 June 2007 » In Appropriate Technology, Hats and Helmets, Materials, Uncategorized »

STF’s developed by Professor Norman Wagner of the University of Delaware, as - if I’ve got the names right a joint project between Delaware Center for Composite Materials and the Army Research Lab. are already in use. (Professor Wagner seems a bit shy, but very proud of his students. The website for his research group is filled with photos of his colleagues, graduate students and undergraduates - but what should be his personal page on the University of Delaware site is a dead link). STFs are added to Kevlar, making ballistic armor more effective;

D30 Labs has been making STF’s available to the civilian market. The Swiss Company RibCap has been making what look like normal knit caps - soft until subjected to a sudden force - at which time they behave like crash helmets:

At the moment not, apparently, available in the United States - but they’re available via some Canadian and British stores - and an American web outlet is apparently underway - for the meantime, that website directs customers to sales at ribcap dash usa dot com.

We’d like to know more - and see test data - but if effective, these soft hats should be in every go-bag - and worn by every emergency responder who’s not already wearing protective headgear.
