preparation example Construction
[0043] figure 1The illustrated embodiment shows that the components of the device used in the preparation method of the chopped carbon fiber reinforced amorphous composite material include: an air inlet 1, a closed high vacuum induction heating spray casting furnace body 2, a thick tube with a A quartz tube with a diameter of 0.5 mm to 2 mm nozzle 3, a water-cooled induction heating coil 4, high-temperature cement 6, a split copper mold with an inner cavity diameter of 2 mm to 30 mm 8, and a closed furnace body 2. The outlet is connected to the valve 9 of the vacuum system; the connection mode of each component of the device is: the split copper mold 8 is placed in the center of the closed furnace body 2, and the water-cooled induction heating coil 4 is arranged on the thick tube of the quartz tube 3 Around the part, the spout part of the quartz tube 3 is in contact with the inner cavity of the split copper mold 8 from the top of the split copper mold 8 and is sealed with high...
Embodiment 1
[0051] The components of the device used in the preparation method of chopped carbon fiber reinforced amorphous composite materials include: air inlet 1, a closed high vacuum induction heating spray casting furnace body 2, and a thick tube with a diameter of 0.5mm~ Quartz tube with 2mm spout 3, water-cooled induction heating coil 4, high-temperature cement 6, split copper mold with an inner cavity diameter of 2mm to 30mm 8, a closed furnace body 2 with a vacuum system connected to the gas outlet on the lower side Valve 9; the connection mode of each component of the device is: the split copper mold 8 is placed in the central position of the closed body of furnace 2, the water-cooled induction heating coil 4 is arranged around the thick tube part of the quartz tube 3, and the quartz tube The spout part of 3 is in contact with the inner cavity of the split copper mold 8 from the top of the split copper mold 8 and is sealed with high temperature cement 6 to avoid air leakage. The ...
Embodiment 2
[0056] The first step, chopped carbon fiber electroless plating:
[0057] Commercial T800 carbon fiber is used for shearing, and then sieved with a 400-mesh sieve, and the chopped carbon fiber under the sieve is taken to obtain a chopped carbon fiber with a length of 30 μm, and the chopped carbon fiber is subjected to electroless copper plating. The process includes: Pretreatment →Sensitization, activation→reduction→plating, in which the pretreatment uses the burning method and organic solvent immersion, the specific process is 1h in a heating furnace at 420°C, then soaked in acetone for 1h, then ultrasonically cleaned with alcohol for 15min, and dried Then use concentrated nitric acid to soak for 1 hour to roughen, then rinse repeatedly with clean water until all residual nitric acid is removed, and then dehydrate and dry with alcohol; for sensitization and activation, put the roughened carbon fiber into the sensitization-activation solution and mechanically stir for 15 minute...
