E up for the Winter Olympics
Not only does it have a beautiful appearance, but the "flying" shell also contains "black technology". Huang Xiangyu, deputy general manager of Sinopec Shanghai Petrochemical Company, said that the ignition system of the torch is all wrapped in the inside of the shell and cannot be seen from the outside. The shell of the torch is made of carbon fiber material, which is very light in the hand.
Lin Shengbing, general manager of Sinopec Shanghai Petrochemical Innovation Research Institute, said that the quality of carbon fiber is only about 1/4 of steel, but the strength is 7 to 9 times that of steel. This time, the R&D team used carbon fiber and resin composite materials to make the Olympic torch, which is the world's first.
