What new material is D3O?
The inventor, Richard M. Palmer, has filed at number of patents on "energy absorbing materials", one of which is US patent (7,381,460). 

On the other hand, there does not seem to be any peer-reviewed publication by Mr Palmer.

There's always the option to ask the manufacturer D30 for further information and/or material samples. 

The possible downside of such a cooperation is that you might not be allowed to report on the progress of your experimental work on conferences or in publications due to an NDA previously signed!
