The carbon fiber (CF) is a new type of fiber material with high strength , high modulus and fiber content is more than 95% . It is made up of organic fibers, such as flake graphite crystallites which are made up of organic fibers along the axial direction of the fibers. It’s a crystallites graphite material by carbonization and graphitization treatment. The carbon fiber is lighter than metal aluminum,but the strength is higher than the iron and steel, it has the characteristics of corrosion resistance and high modulus,the carbon fiber is the important material in the national defense and civilian areas . It not only has the intrinsic characteristics of carbon materials, but also has the flexibility of textile fibers,it…
The isostatic pressure graphite is a kind of new graphite material. Because it have a series of and good characteristic, from but make it with the high and nwe technique of the now, the sophisticated technique in national defense is join close mutually. It is graphite crystallize machine that single crystal silicon furnace in manufacturing that material, the metals continuum casting the electricity spark processes to use graphite eletrode can't substitute etc. Also is extremely good material for make a fire pole of the rocket, encourage the pole and spray the mouth with the rudder plank,and a deceleration materials and reflect materials in the graphite nuclear reactor. Carbon graphite materials in the manufacturing process, due to the different molding methods,…
According to the change of the surface wettability of graphite felt, the operation conditions of Shi Mozhan's treatment were determined. The graphite felt acid treated with nitric acid treated as an electrode material, the surface wettability of graphite felt significantly increased after acidification treatment, the surface contact angle decreased with graphite felt, graphite felt nitric acid is used as electrode material, current output increased and stable. Microbial fuel cell is a microbial as the anode catalyst, can be directly in the water samples can be degraded organic compounds of chemical energy into electrical energy. The performance of anode material usually directly affects the rate of electron transfer and mass transfer, and then affects the performance of the sensor. Graphite felt…
