摘要：A new type of modified bismaleimide (BMI) resins with good heat resistance and processing properties for advanced composites was developed. Modifiers hydrogen silsesquioxane (HSQ), dipropargyl ethers of bisphenol A, hexafluorobisphenol A, 4,4'-dihydroxydiphenyl ether and resorcinol were used to modify 4,4'-bismaleimidodiphenylmethane. The structure of the resins was verified by Fourier transform infrared spectrometry. The relationship between viscosity and temperature was used to characterize the processability of the resins. The curing behaviors of resins were investigated by a differential scanning calorimeter. The glass transition temperatures and thermal stabilities of cured resins were investigated by dynamic mechanical analysis and thermogravimetric analysis, respectively. The relationship between structures and properties of the resins was discussed, and the mechanical properties of the glass-fiber-fabric-reinforced composites were measured.
