Abstract:

Development of a new Advanced Combat Helmet liner design using the novel idea of including filler materials inside channels in the liner is well underway. An energy absorbing foam has been selected for the main liner structure, and several filler material candidates of widely varying properties are being considered. To date material has been evaluated both experimentally and numerically. In the very near future tests will commence on three dimensional prototypes of the newly designed liner. Numerical studies will include coupled simulations with a detailed finite element head model, providing insight into the effect of the new liner on the brains response to a blast wave impact.
