A kind of bismaleimide resin composition, its preparation method and application |
| abstract |
The invention discloses a bismaleimide resin composition, a preparation method and application thereof. It belongs to the technical field of polymer materials, and the bismaleimide resin composition is prepared from raw materials comprising the following components in parts by weight: 50-70 parts of bismaleimide monomer; 5-15 parts of cyanate ester resin parts; 15-35 parts of allyl compounds; 7-32 parts of imidazole group-containing polyarylene ether nitrile resin; and 0.02-0.8 parts of imidazole-based accelerators. In the bismaleimide resin composition provided by the present invention, the imidazole group-containing polyarylene ether nitrile resin cooperates with other components to improve the toughness of the obtained composite material, and at the same time, the obtained bismaleimide The amine resin composition obtains higher tensile strength and modulus after curing. In addition, the carbon fiber composite material prepared from the bismaleimide resin composition has higher interlaminar shear strength and better toughness, and is suitable for higher service temperatures. |
