The silk bullet-proof vest can withstand .38 and .22 calibre bullets fired from a distance of three metres, Panomkorn Khwakhong, a researcher at KKU's chemical engineering department, said during a press at the University recently.
According to the Bangkok Post, the armour, made from silkworm cocoons mixed with a special resin and then hydraulically compressed, is durable and lightweight, said Panomkorn, a chemical engineering lecturer.
The vests are 14-20 millimetres thick, weigh 2.5-4 kilogrammes, and cost only one-third the price of conventional 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. Panomkorn's research team collected data and interviewed silkworm raisers and a silk textile handicraft groups in Phu Wiang district and learned about the properties of the cocoons.
“Inspired by the violence in the deep South that has claimed many lives and left security officers there dead and injured, our team decided to develop a bullet proof-vest from silkworm cocoons. They are a raw material in the Northeast and plentiful in Khon Kaen province,'' the newspaper quoted Panomkorn as saying.
The significant characteristics of the cocoons, durability and flexibility, were used to develop the vest using chemical engineering principles.
Testing showed the vest could withstand .38 and .22 bullets fired from a distance of three metres, which is level one protection under the National Institute of Justice's standards.
Panomkorn said the silk vest is also able to take repeated hits without deteriorating. His team plans to continue developing the vest and make a version that can withstand automatic weapons fire, such as the M16 assault rifles used by insurgents in the South. .
His team has already obtained a patent for the vest, which also won first prize at a recent local knowledge innovation project contest. (SH)
