Summary

-The experiment proposed the use of layered polymers as outer coatings to help reduce linear acceleration and rotational acceleration.

-Dow Corning Compound, a shear thickening polymer was used on one helmet.

-5 different levels of Sorbathane, a shear thinning polymer were used on another helmet.

-Final helmet was original from manufacturer and used as a control.

-All three came from same controls (age of helmet, level of use, never refurbished, model, manufacturer, and size).

-Sorbothane (70-duro) was found to be the most effective; reduced linear acceleration by 5.8% and 10.8% at the side and front boss locations (areas of helmet measured).

-Sorbothane (70-duro) reduced rotational acceleration by 49.8% at the front boss location.

-These findings are significant as current data suggests that the majority of force transmitted to the brain in heavy contact sports occurs through linear acceleration and rotational acceleration.

*Front Boss is just to either side of the mid-line of the helmet in the front.
