Improved Thermal-Mechanical Performance of Polyimide Composites by Structural Design

The incorporation of a “graphene-carbon nanotube-graphene” structure as a filler in polyimide composites to enhance their mechanical and thermal properties was investigated. The performance of the composites was evaluated by molecular dynamics simulations. Findings revealed that this arrangement significantly enhanced the mechanical strength and stiffness of the composites, improving their tensile and shear properties.
