Abstract

The invention relates to a high-compressive-strength low-density material and application thereof, and belongs to the field of composite materials. The preparation method comprises the following steps: preparing sulfur-containing graphite oxide, and then dispersing the sulfur-containing graphite oxide into a water-alcohol mixed solution; then adding ferrocene into the sulfur-containing graphite oxide dispersion liquid in a protective gas atmosphere, controlling the reaction temperature to be 900-1600 DEG C, and collecting a gasification product to obtain carbon nanotube aerosol; and finally mixing the carbon nano tube aerosol with a high polymer material to obtain the carbon nano tube aerosol. According to the invention, the material is low in density and high in compressive strength, andis extruded by screw extrusion equipment to obtain a high-compressive-strength low-density material filament, and the filament is used as a 3D printing material.

Description

technical field

[0001] The invention relates to a material with high compressive strength and low density and its application, which belongs to the field of composite materials. Background technique

[0002] Sustainable development is a very important initiative of today's era, and it is also the future that mankind will eventually move towards. In today's increasingly severe environmental problems, all industries are trying their best to save energy and reduce emissions. Among them, lightweight technology is particularly important, especially in the fields of automobiles, ships, aerospace vehicles, etc., and the discovery of each lightweight material may promote an industry change. The so-called lightweight is not "unscrupulous" to reduce weight blindly. It means to reduce weight as much as possible while ensuring performance (stiffness, strength). The use of common alloy materials is a good example.

[0003] In the field of portable equipment, such as portable seawater d...
