  Personal protective materials used to reduce shock impacts are available on the market for use in the sports and industry sector. Many of the materials may attenuate vibrational impact forces and protect the human body from potential injuries incurred during long term exposure. An experiment was performed to evaluate material energy absorption level, displacement effectiveness, and dampening characteristics, for two different recoil pads and one back protector D3O® materials, as well as two silicone based viscoelastic rubbery materials. Low, medium, and high energy impact levels, similar to impact forces produced by percussive power hand-held tools (i.e., rivet guns) were applied to all five samples of the materials using a low velocity impact tower to measure materials energy absorption and calculate dampening ratios. Material D3O® indicated a higher ene.. View More»
