Patent abstract
A composite multi-axial impact protection liner for a helmet is provided that reduces rotational acceleration, rotational strain rate, and rotational strain that cause concussions. In a protective helmet so equipped, one or more layers of fluid polymer, including strain thinning and strain thickening polymers, are positioned between the wearer's head and a hard helmet shell. The liner offers greater injury protection, performance, and personal comfort using the rate dependent and combined effect of strain thinning and strain thickening of fluid polymer layers.
