..., indicating need for enhanced protection. An elastomeric honeycomb helmet design is proposed herein as an alternative to EPS foam to improve TBI protection and be potentially reusable for multiple impacts, and tested using a twin-wire drop tower. Small-scale normal and oblique impact tests showed honeycomb...

... impact testing (impulse hammer and custom drop tower) on flat and socket shaped composite samples to evaluate composite layer options. Sample vibration dissipation was measured by a combination of accelerometers, load cells, and a dynamometer. Composite sockets made purely of flax fibers were lighter...

... of this review was to provide a basis for developing new sports headgear impact tests for standards by summarizing and critiquing the following: (1) impact testing procedures currently codified in published headgear standards for sports and (2) new or proposed headgear impact test procedures in published...
