Embodiment 1

[0050] 5 grams of multi-walled carbon nanotubes are placed on the vibrating screen 3, nitrogen is filled into the sealed insulating casing 11 through the air hole 12, the air hole 12 is sealed with a sealing sleeve 13, and the high voltage generated by the electrostatic generator 10 is applied at a high voltage of 50 kV. Static electricity forms a high-voltage electrostatic field between the vibrating screen 3 and the foundation groove 4. The frequency of the vibration motor is 20 kHz. In the field, under the action of the electric field force, the orientation occurs along the direction of the electric field force, and it is quickly implanted into the aluminum liquid in the mesh groove in the base groove 4, and the aluminum liquid is cooled and solidified to obtain a network-shaped aligned carbon nanometer. Tube aluminum composite products.

Embodiment 2

[0053] 2 grams of carbon nanotubes are placed on the vibrating screen 3, and the high-voltage static electricity generated by the high-voltage electrostatic generator 10 with an applied voltage of 70 kilovolts makes a high-voltage electrostatic field between the vibrating screen 3 and the base groove 4, and the vibrating frequency is 1000 Hz. Under the action of the vibrating motor 6, the carbon nanotubes are evenly sprinkled into the high-voltage electrostatic field formed by the vibrating screen 3 and the foundation groove 4, and then they are oriented along the direction of the electric field force under the action of the electric field force, and are quickly implanted into the foundation groove 4 In the polyacrylonitrile solution in the mesh groove, the polyacrylonitrile solution is solidified to obtain a linearly aligned carbon nanotube polyacrylonitrile composite fiber, and the carbon nanotube polyacrylonitrile composite material can be carbonized to obtain a composite car...

Abstract

The invention relates to a directional carbon nanometer tube composite material, and relative high-speed production and device.

Description

technical field [0001] The invention belongs to the field of materials, and relates to an aligned carbon nanotube composite material, a high-speed preparation method and preparation equipment. Background technique [0002] Carbon nanotubes were discovered by S.Iijima in 1991. Their diameter is thousands of times smaller than that of carbon fibers, and their performance is far superior to that of glass fibers commonly used today. One of its main uses is as a reinforcement for polymer composites. [0003] The mechanical properties of carbon nanotubes are quite outstanding. The average elastic modulus of multi-walled nanotubes has been measured to be 1.8TPa. The experimental value of the strength ratio elastic modulus of carbon nanotubes is 30-50GPa. Although carbon nanotubes have such high tensile strength, they are not as brittle as carbon fibers. Carbon fibers break at about 1 percent deformation, while carbon nanotubes do not break until about 18 percent deformation. T...
