摘要

研究了在聚酰亚胺复合材料中加入 "石墨烯-碳纳米管-石墨烯 "结构作为填料以增强其机械和热性能的问题。通过分子动力学模拟对复合材料的性能进行了评估。研究结果表明，这种排列方式大大提高了复合材料的机械强度和刚度，改善了其拉伸和剪切性能。

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.
