Preparation method of aerospace special high-performance composite material presoak

Abstract

The invention discloses a preparation method of an aerospace special high-performance composite material presoak, and relates to the technical field of composite materials. The aerospace special high-performance composite material presoak is prepared from modified acrylamide-acrylic resin, the resin can be dissolved in water to prepare an emulsion, and the adhesive property is good; carbon fibersare used as a main material, self-made resin, nanofiller, a coupling agent and a curing agent are added to obtain the presoak containing the carbon fibers, the presoak is used for impregnating basaltfibers, and a carbon fiber layer can be formed on the outer layers of the basalt fibers after high-temperature roasting, so that the use amount of the carbon fibers in the material is reduced, and thestrength of the material is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a high-performance composite material prepreg solution special for aerospace. Background technique: [0002] In recent years, the application of composite materials in the aerospace field has become wider and wider, and the performance requirements of composite materials have become higher and higher. The interface between the composite reinforcement and the matrix and the dispersion of the reinforcement have become the bottleneck of the performance improvement of composite materials. Carbon materials such as graphene and carbon nanotubes have excellent mechanical properties and are often used as reinforcements. However, the hydrophobicity of graphene materials limits its application. [0003] Carbon fiber is a high-strength, high-modulus fiber material with a carbon content of more than 95%. However, carbon fiber is mostly imported and the price is ...

Problems solved by technology

Carbon materials such as graphene and carbon nanotubes have excellent mechanical properties and are often used as reinforcements. However, the hydrophobicity of graphene materials limits their applications.

[0003] Carbon fiber is a high-strength, high-modulus fiber material with a carbon content of more than 95%. However, most carbon fibers are imported and the price is relatively high. If all materials are made of carbon fibers, it will undoubtedly increase the processing cost of the material.

In addition, most of the impregnation methods commonly used in this field currently use organic solvents as diluents, which have the problems of difficult solvent volatilization and pollution of the processing environment.
