Abstract: The Walter Reed Army Institute of Research (WRAIR) projectile concussive impact (PCI) model is designed for preclinical analysis of concussion on male adult Sprague-Dawley rats. This model represents a noninvasive, closed-head injury caused by blunt impact and is used to study mild traumatic brain injury (TBI). Materials analysis completed within the US Army Research Laboratory (ARL) was verified by WRAIR through experimental testing. Based on these results, ARL designed and fabricated composite helmets that assured that the rats in the trial were protected against injury greater than mild TBI or concussion. This technical note is a description of the rat helmet fabrication process.
