Thai university develops silk bullet-proof vest

Bangkok, September 1: A team of university researchers in Thailand has developed the world’s first bullet-proof vest made from tural silk, a media report said on Tuesday. The vest can withstand .38 and .22 calibre bullets fired from a distance of three metres, Panomkorn Khwakhong, a researcher at Khon Kaen University’s chemical engineering department, said. The armour, made from silkworm cocoons mixed with a special resin and then hydraulically compressed, is durable and lightweight, the Bangkok Post quoted Panomkorn, a chemical engineering lecturer as saying. The vests are 14-20 millimetres thick, weigh 2.5-4 kgs, and cost only one-third the price of conventiol bullet proof vests, he said. He said silkworm cocoons were used because silkworms are raised and farmed in many areas of Khon Kaen, which has a reputation for quality silk clothing. (IANS)
