New helmet lining material: Lighter, better absorbing, cooler

A new material developed at HRL Lab, California, USA promises to change the current helmet structure.

This material is light, dry, wearing a hat without being stuck like it is now.

This material allows better absorption of force in the event of an accident, but is lighter and more dry, wearing a hat that is not clogged as it is now. When tested, the polymer frame with a structure similar to the Eiffel Tower absorbs 27% better force than the best polystyrene foam on the market now, 48% better than the highest grade vinyl nitrile foam.

To create this new helmet lining, scientists used liquid plastic and UV-acting. Under the action of ultraviolet rays, liquid plastics form different polymer structures, which can fine-tune the hardness and elasticity of the pads.

This technology can be used not only in helmets, but also as a shockproof packaging for electronics, or as a car interior lining. However, the technology for making polymer pads is being prepared to be commercialized for sports helmets such as rugby and cycling.
