A scientist textile technology experts from the Royal Melbourne Institute of Technology (RMIT) has developed a new material for bulletproof vest material that is lighter and cheaper.
Bulletproof vests for a long time using the raw material Kevlar, which is a synthetic fiber as strong as steel. As a result, the proof vest bullet ward off attacks, but tend to be heavy and stiff. However, Dr Rajiv Padhye successfully developed a vest which is made from a mixture of wool and Kevlar.
With the help of nanowire technology, this vest becomes lighter. According to Padhye, knitted wool that meeting to reduce the thickness of the kevlar. While the vests made from Kevlar need 36 layers, vests made from Kevlar-wool blend is only 30 layers.
In research funded by the Australian Wool Innovations and published in the Textile Reseach Journal is stated, the cost of production vest also become more efficient. Kevlar material prices around 70 U.S. dollars per kilogram compared with 12 U.S. dollars for 1 kg of wool.
Padhye in collaboration with colleagues, Lyndon Arnold, said that ballistics tests have shown that the best composition is 20-25 percent and 80-75 percent kevlar wool. He plans to commercially produce this vest. Until now still a prototype vest.
