Preparation and Properties of Graphene Reinforced Carbon Fiber Composite Laminates.

Graphene/carbon fiber composite laminates were prepared by vacuum assisted resin transfer molding process. The effects of different structural forms of graphene with different mass fractions on the tensile properties of carbon fiber composite laminates were investigated. First, the graphene monolayer and multilayer graphene were distributed evenly into epoxy resin by ultrasonic dispersion. Then, single-layer and multilayer graphene/carbon fiber composite laminates were prepared by vacuum assisted resin transfer molding process. Finally, tensile testing machine was used to test the tensile properties of composite laminates. The results show that when the mass fraction of graphene is 0.03%~0.10%, the tensile properties of the specimens are gradually improved with the increase of the mass fraction of graphene. When the mass fraction of multilayer graphene is 0.03%~0.10%, the tensile properties of the specimens gradually decrease with the increase of the mass fraction of multilayer graphene.
