文摘

High performance polybenzoxazine resin can be obtained by introducing partially reduced graphene oxide (PRGO) into bis-benzoxazine (B-BOZ) resin to overcome the defects such as low char yield, weak mechanical properties, and poor toughness of B-BOZ resin. By virtue of the good thermal resistance and graphitization acceleration of PRGO, thermal resistance especially char yield of B-BOZ resin can be greatly improved to 62.1% at 800°C in nitrogen. Moreover, with the folds deformation and the crack deflection of PRGO in B-BOZ resin, the mechanical properties such as flexural strength and interlaminar shear strength of the carbon fiber reinforced B-BOZ composite, could be greatly increased by PRGO without a decrease on modulus of B-BOZ composite.
