us and canadian skiers get smart armour - where to buy a smart board

Will KnightA futurist flexible materials harden into armor immediately upon impact, which Will protect US and Canadian skiers from injury during the turn-around competition at this Winter Olympics.
The lightweight, flexible material is called d3o and can be worn under a normal ski suit.
It will provide protection for American and Canadian skiers participating in the slalom and giant slalom competitions in Turin, Italy.
Skiers usually have to wear bulky arm and leg guards to protect themselves from the pole placed along the swing track.
S. -based Colorado-based Spidel company a few months ago, members of the U. S. and Canadian Olympic Alpine skiing teams had the opportunity to try it out on their calves and forearm.
Richard Palmer, uk ceo, claims: "Now they like it and won't ski without it --"
D3o Labs based on the development of this material.
While the exact chemical composition of d3o is a trade secret, Palmer says the material is synthesized by mixing the viscose fluid with the polymer.
After synthesis, pour the liquid d3o into the mold that matches the shape of the body part it will protect.
The resulting material has material properties called "strain rate sensitivity.
Under normal circumstances, the molecules in the material are weakly bound and can easily pass through each molecule to make the material flexible.
However, the impact of sudden deformation leads to the strengthening of chemical bonds and the locking of moving molecules, making the material a stronger protective barrier.
In laboratory testing
Its manufacturers claim that the guards provide as much protection as most conventional protection materials.
But Phil Green, research director at the d3o Lab, said it was difficult to accurately measure the properties of the material because the hardening effect only lasted until the impact itself.
However, Green believes that the property of d3o may be changed for the new impact
Protection and opposition
Application of trauma.
"Of course, there is a chance to get involved in chemistry and improve the effect," he told the New Scientist . ".
Another potential application could be sound. proofing.
The propagation of sound waves should produce strain similar to the impact, so it may be feasible to create a material that becomes more soundproof as the noise increases.
"It may have some very interesting, unexplored features," said Green . ".
