NOVELTY - Preparing high dispersion graphene reinforced bismaleimide resin matrix composite material involves graphene-enhanced bismaleimide resin-based composite precursor, inhaling pure buma resin into the porous structure of graphene sponge by vacuum infusion method by vacuum method. The high-dispersion graphene-reinforced bismaleimide resin-based composite material slurry and graphene sponge pre-perfused are used with bismale resin as a precursor. The graphene sponge is filled with the double horse resin is broken by shearing by ultrasonic method to obtain graphene-filled buma resin slurry, mixed the graphene-filled buma resin slurry and the pure buma resin matrix to obtain a highly-dispersed graphene-reinforced resin-based composite slurry. The high-dispersion graphene-reinforced bismaleimide resin-based composite material slurry is injected into mold. The vacuum defoaming is carried out, and temperature field is controlled to meet the curing requirements, after the curing is completed. USE - Method for preparing high dispersion graphene reinforced bismaleimide resin matrix composite material. ADVANTAGE - The method enables to prepare high dispersion graphene reinforced bismaleimide resin matrix composite material that improves the mechanical properties of the double horse resin matrix and temperature resistance of the double horse resin.
