MITSUBISHI Will Expand U.S. Carbon Fiber Production Capacity

< p > recently, MITSUBISHI liyang's subsidiary company, < a href= "http://www.91se91.com/news/index_c.asp" > MITSUBISHI Liyang < /a > carbon fiber and composite materials company, announced that it will expand its carbon fiber production capacity in Sacramento, California, and expand its base carbon fiber production capacity from 2000 tons to 4000 tons / year. It is expected to complete capacity expansion in the middle of 2016. < /p >
< p > MITSUBISHI Liyang said that the global demand for a href= "http://www.91se91.com/news/index_c.asp" > carbon fiber < /a > demand increased by more than 20% per year, especially the light weight solution of renewable energy and fuel efficiency is driving the rapid growth of carbon fiber applications. < /p >
In industrial applications, carbon fiber composite pressure vessels are widely used in compressed natural gas storage tanks and large compressed natural gas transport containers. More and more large buses and trucks also tend to use compressed natural gas fuel. P < /p >
< p > in addition, the a href= "http://www.91se91.com/news/index_c.asp" > the fuel tank of the fuel cell vehicle equipped with /a high pressure hydrogen and the hydrogen storage tank also use a large number of carbon fibers. By 2020, more carbon fiber materials will be needed in the field of clean energy production and consumption. The company decided to expand carbon fiber production capacity based on the above reasons. < /p >

< p > weaving the upper shaft and weft yarn of the warp shaft on the extra wide electronic dobby loom. The loom speed is 390 revolutions / minutes, and the nozzle is configured as 75/40. For better analysis. Under the condition of constant warp tension and constant water pressure, that is, the specifications of the pump are 28 millimeters, the P value of the spring diameter is 11.5 mm, the number of turns is 7.5 rings, and the length is 145 millimeters. The weft insertion process parameters are debugged and the test time is 24 hours. < /p >
In the second test, the loom efficiency is not high; in the test 2, because the water is too long and the water is small, the time of flow and yarn to the waste side yarn is ahead, and the weft yarn is easily towed under the traction of the lack of residual water, causing the weft yarn not to enter the weft opening properly, causing the loom to stop and the weft on the cloth. In test 3, under the condition of reasonable water volume, the first water volume is properly increased, and the weft yarn is always wrapped by water in the flight. The time of the flow and yarn to the waste yarn is punctual, the residual water is just right, the weft yarn goes smoothly into the weft opening during the weft insertion time, the loom runs well, and the weaving efficiency is 99%, which can meet the requirements of normal production. < p > from the following table, it is known that in Experiment 1, due to the shorter initial water and larger water volume, the flow of yarn and yarn to the waste side yarn is later than that of the weft yarn entering the weft opening. < /p >
< p > when weaving weave fabric with water jet weaving, the width of weft yarn is longer and the flying time of weft yarn is longer. In addition, the water pressure should be increased to make the weft yarn straightened into the fabric, and the weft can arrive at the design time to form the fabric. After repeated commissioning, the loom's overall efficiency can be over 98% and efficient production can be achieved. < /p >
