Might pearls assist save a soldier’s life?
Scientists are pearls in an progressive U.S. Military analysis venture to bolster physique armor.
Researchers on the College of Buffalo have simulated mom of pearl, or the outer coating of pearls, to create a light-weight plastic described as 14 occasions stronger and eight occasions lighter than metal. In a press release, the Military says that the fabric is “very best for absorbing the influence of bullets and different projectiles.”

“The fabric is stiff, sturdy and hard,” stated Shenqiang Ren, Ph.D., a professor within the Division of Mechanical and Aerospace Engineering at Buffalo College and the paper’s lead writer, within the assertion. “It could possibly be relevant to vests, helmets and different varieties of physique armor, in addition to protecting armor for ships, helicopters and different automobiles.”
Ren can be a member of the College at Buffalo’s RENEW (Analysis and Training in eNergy, Setting and Water) Institute.

A lot of the materials used is a “souped-up model of polyethylene,” in line with the Military. This ultrahigh molecular weight polyethylene, or UHMWPE, is used for the likes of synthetic hips and guitar picks.

Researchers have studied the construction of mom of pearl, which is created by mollusks who prepare a type of calcium carbonate into one thing that “resembles interlocking bricks.”
“Like mom of pearl, the researchers designed the fabric to have a particularly powerful outer shell with a extra versatile inside backing that is able to deforming and absorbing projectiles,” the Military stated in its assertion.

“In distinction to metal or ceramic armor, UHMWPE is also simpler to forged or mildew into complicated shapes, offering versatile safety for troopers, automobiles, and different Military belongings,” stated Evan Runnerstrom, Ph.D., program supervisor, supplies design at ARO, within the assertion.
