Abstract

The invention provides a preparation device and a preparation method for a carbon nano tube resin film, relates to a preparation method for a carbon nano tube resin film and a two-way stretch device, and belongs to the technical field of nanocomposite preparation technology. The preparation device comprises a working table and a vacuum infusion mold platform. A quadrangular material platform is arranged on the working table. The two-way stretch device is arranged around the material platform. A temperature sensor and a paperclip-shaped heating tube are arranged on the material platform. A system control platform is arranged on the working table. A vacuum bag is arranged on the vacuum infusion mold platform. A vacuum bag sealing strip is arranged at one side of the vacuum bag. The vacuum bag is connected with a vacuum-pumping joint and a vacuum-measuring joint. A resin inlet channel, a resin flow-guiding strip and a resin outflow pipe are arranged between the vacuum bag and vacuum infusion mold platform. The dispersity of carbon nano tubes is controlled accurately and the enhanced effect of carbon nano tubes to composites is raised.

Description

technical field [0001] The invention relates to a method for preparing a carbon nanotube resin film and a bidirectional stretching device thereof, and belongs to the technical field of nanocomposite material preparation technology. Background technique [0002] Since carbon nanotubes were discovered by Japanese scientist Iijima in 1991, due to their unique mechanical, thermal, electrical and photoelectric properties, they have become an important part of the field of nanoscience research. Carbon nanotubes are a new kind of nanomaterials. Experiments and theoretical calculations show that carbon nanotubes have extremely high strength and ideal elasticity, and the Young's modulus can even reach 1.3TPa. The aspect ratio of carbon nanotubes is more than 1000, and the strength is 100 times higher than that of steel, but the weight is less than 1 / 6 of steel. [0003] Due to the above-mentioned unique properties, carbon nanotubes, once discovered, quickly attracted widespread inte...

AI Technical Summary

Problems solved by technology

The danger of chemical reagents has strong oxidative properties, and this method will damage the structure and mechanical properties of carbon nanotubes to a certain extent

Secondly, after the carbon nanotubes are dispersed in the composite material, because they are not arranged according to the fixing method, and the carbon nanotubes themselves have anisotropy, the reinforcing effect on the composite material is limited, and it is far from reaching the use value of the carbon nanotubes.

Most of the existing carbon nanotube orientation methods have the problem of low orientation degree and carbon nanotube damage.
