Abstract
It remains unknown how helmet shells from different sports compare. Our objective was to compare the material properties of the protective outer shells of various athletic helmets in their manufactured form. We cut sections from each of the 3 different helmets (Bauer RE-AKT hockey helmet, Cascade R lacrosse helmet, and Riddell Speed Flex football helmet) at 4 different locations (front, side, top, rear) for 12 total samples. The different helmet brands and locations served as the independent variables. We measured stiffness2/load, phase angle, hardness, and modulus using nanoindentation. The interaction between helmet type and location was significant for the modulus (P<.001), hardness (P<.017), phase angle (P<.001), and stiffness2/load (P<.001). Further investigation of helmet designs and mechanical properties is warranted to determine how these properties relate to performance and if new modifications can be made to improve protective athletic helmet performance.
