specific Embodiment approach 1

[0016] Specific implementation method 1: The preparation method of a epoxy resin composition in this embodiment is based on the following steps:

[0017] Step 1: Illects: Take 70 to 100 copies of epoxy resin, 1 to 10 copies of polyacryonic acid, 1 to 10 parts of polyurethane and 0.01 ~ 0.1 copies of catalyst at the weight number;

[0018] Step 2: Heat the 70-100 copies of epoxy resin that takes step one to 140 ° C to 160 ° C, and then add 1 to 10 polypropylene acid and 1 to 10 polyurethane of the steps. The catalyst of 0.01 ~ 0.1 copies of the first name reaches 1.2h to 1.8h under the condition of 140 to 160 ° C to obtain an epoxy resin composition.

specific Embodiment approach 2

[0019] Specific implementation method 2: The difference between this implementation method and the specific implementation method is that: 90 epoxy resins referred to in step 1, 5 copies of polyacrylate, 5 polyurethane, and 0.05 copies of catalysts, catalysts, catalysts, catalysts, catalysts, 0.05 copies, and catalysts.

Abstract

The invention discloses a preparation method of an epoxy resin composition and a method of preparing an M type carbon fiber / matrix resin composite by virtue of the preparation method as well as relates to the preparation method of the epoxy resin composition and the preparation method of the M type carbon fiber / matrix resin composite. The invention aims to solve the problem that epoxy resin prepared by the prior art has weak interfacial strength when being used for preparing the M type carbon fiber / matrix resin composite, and provides the preparation method of the epoxy resin composition and the method of preparing the M type carbon fiber / matrix resin composite by virtue of the preparation method. According to the preparation methods disclosed by the invention, the epoxy resin composition is prepared by adding polyacrylic acid and polyurethane in epoxy resin; and the M type carbon fiber / matrix resin composite is prepared from the steps of preparing an epoxy resin composition solution, mixing the epoxy resin composition solution and a matrix resin solution, soaking a carbon fiber by the mixture, and preparing the M type carbon fiber / matrix resin composite by carrying out drying, mould pressing and solidifying on the soaked carbon fiber. The preparation methods are used for preparing the M type carbon fiber / matrix resin composite with strong interfacial strength.

Description

technical field [0001] The present invention involves a preparation method for the preparation of epoxy resin combinations and a M -race carbon fiber / substrate resin composite material. Background technique [0002] The improvement of the intensity of the composite material interface is largely relying on fiber surface performance. There are many fiber surface treatment methods. Among them, the coating method is the simplest and practical. Such surfactants are mainly organic silicon coupling agents, titanate, complex, etc., and coat on the fiber surface under certain conditions to improve Interfacial shear strength of composite materials. However, after using these treatment agents, the intensity of certain fiber interface with high modular amounts is small or even without effect. Although the usual epoxy resin has a good adhesive strength for metal materials, the strength of non -metal materials is low, especially for fiber. There is a problem with low interface strength...
