Abstract

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.
