| titleOfInvention | Bismaleimide resin composition, preparation method and application thereof |
| abstract | The invention discloses a bismaleimide resin composition, a preparation method and an application thereof. Belonging to the technical field of high polymer materials, the bismaleimide resin composition is prepared from the following raw materials in parts by weight: 50-70 parts of a bismaleimide monomer; 5-15 parts of cyanate ester resin; 15-35 parts of allyl compounds; 7-32 parts of imidazolyl-containing poly (arylene ether nitrile) resin; 0.02-0.8 part of imidazole accelerator. In the bismaleimide resin composition provided by the invention, the imidazolyl-containing polyarylether nitrile resin is matched with other components to perform synergistic action, so that the toughness of the obtained composite material can be improved, and the bismaleimide resin composition can obtain higher tensile strength and modulus after being cured. In addition, the carbon fiber composite material prepared from the bismaleimide resin composition has high interlaminar shear strength and excellent toughness, and is suitable for high use temperature. |
