Example Embodiment

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

[0013] A modified resin composite material, in parts by weight, including 31 to 37 parts of bismaleimide, 28 to 33 parts of diaminodiphenylmethane, and 25 to 31 parts of bisphenol A epoxy resin , 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: bismaleimide and diaminodiphenylmethane are mixed and stirred uniformly in an environment of 120°C, and prepolymerized at 120~130°C for 20 minutes, and then bisphenol is added. Stir A-type epoxy resin evenly, pour it into the mold and degas it in vacuum for 20 minutes, then heat it up to cure; soak the alkali-free glass fiber cloth in the silane coupling agent and antioxidant mixture and bake it at 130°C until it is dry; The sample after the above-mentioned heating and curing is mixed w...

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...
