Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with embodiments.

[0013] A modified resin composite material, comprising 31 to 37 parts of bismaleimide, 28 to 33 parts of diaminodiphenylmethane, and 25 to 31 parts of bisphenol A epoxy resin in parts by weight , 4~9 parts of alkali-free glass fiber cloth, 3~5 parts of silane coupling agent, 1~3 parts of antioxidant.

[0014] Among them, the preparation method of the composite material includes the following steps: mix and stir bismaleimide and diaminodiphenylmethane in proportion at 120°C, prepolymerize at 120-130°C for 20 minutes, and then add bisphenol Stir the type A epoxy resin evenly, pour it into the mold for 20 minutes to remove air bubbles in a vacuum, and then heat up to cure; soak the non-alkali glass fiber cloth in the mixture of silane coupling agent and antioxidant and bake it at 130°C until it is dry; The above temperature-cured sample was mixed with alkali-free glass fiber cloth a...

Abstract

The invention discloses a modified resin composite. The modified resin composite is prepared from, by weight, 31-37 parts of bismaleimide, 28-33 parts of diaminodiphenylmethane, 25-31 parts of bisphenol-A-type epoxy resin, 4-9 parts of alkali-free glass fiber cloth, 3-5 parts of silane coupling agent and 1-3 parts of antioxidant. The modified resin composite is excellent in electrical insulation property, good in toughness, resistant to high temperature, excellent in mechanical property and capable of being widely applied to electrical insulating materials, abrasion-resistant materials, aerospace materials and the like.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a modified resin composite material. Background technique [0002] Bismaleimide resin has excellent electrical insulation properties, high temperature resistance, chemical resistance, environmental resistance and radiation resistance, and can be used as a matrix resin for high-performance composite materials. However, its poor toughness hinders its further application. In order to improve its shortcomings, it is necessary to introduce other materials to improve the overall comprehensive performance. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, provide a modified resin composite material, and meet the basic needs of the market. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effect, the present invention is realized through the following...
