preparation example Construction

[0042] The preparation method of the epoxy resin composition of the present invention is to uniformly mix the raw materials of the epoxy resin composition according to their proportions.

[0043] The prepreg of the present invention can be produced by dissolving the epoxy resin composition of the present invention in an organic solvent, impregnating it into reinforcing fibers, taking it out, and evaporating the solvent using an oven or the like; The resin composition is heated to impregnate the reinforcing fibers, and then it is only necessary to take it out and cool it.

[0044] The carbon fiber-reinforced epoxy resin composite material of the present invention can be obtained by thermocompression curing molding of the above-mentioned carbon fiber prepreg.

[0045] The epoxy resin composition of the present invention and its carbon fiber prepreg and carbon fiber composite material can be used in various aspects of industrial production and people's life, such as aerospace fie...

Abstract

The invention belongs to the field of materials, and particularly relates to an epoxy resin composition for carbon fiber prepreg. The epoxy resin composition is prepared from the following componentsin parts by weight: 100 parts of biphenol-A epoxy resin, 10 to 30 parts of unsaturated polyester, 10 to 50 parts of carbon-chain polymer, 5 to 50 parts of filler, and 0.2 to 2 parts of organic peroxide. The epoxy resin composition provided by the invention is high in binding force with a carbon fiber interface, a composite material reinforced by the carbon fibers is excellent in mechanical performance, low in curing shrinkage rate, high in product dimensional precision and good in sterilizing and antibacterial effect.

Description

technical field [0001] The invention belongs to the field of materials, in particular to an epoxy resin composition for carbon fiber prepreg. technical background [0002] Epoxy resins generally refer to organic compounds containing two or more epoxy groups in their molecules. Due to the active epoxy groups in the molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble polymers with a three-way network structure. The cured epoxy resin has good physical and chemical properties, it has excellent bonding strength to the surface of metal and non-metal materials, good dielectric properties, small deformation shrinkage, good dimensional stability of products, high hardness, flexibility It has good resistance and is stable to alkali and most solvents, so it is widely used in various fields of people's production and life, and can be used for pouring, impregnation, lamination, adhesives, coatings, etc. [0003] Carbon fib...
