摘要整理
拉挤玻纤增强复合材料（pGFRP）已广泛应用于格构式输电塔的横臂结构中，因其高强度-质量比和轻量化特性而被选用。然而，研究表明现有复合材料横臂在蠕变、扭转变形、屈曲、吸湿、温度剧变等环境因素作用下性能衰减，导致复合材料失效，服役寿命缩短。为解决此问题，研究人员提出了套筒安装、加设支撑系统、在核心结构中加入pGFRP复合梁等改进方案，以实现可持续的复合材料结构设计。这些改进措施通过提高刚度、改善弯曲性能、增强能量吸收能力和提升承载能力，使复合材料结构在机械载荷作用下表现出优异性能。尽管相关文献存在不足，但已有多项关于复合材料横臂和梁结构增强的研究成果。本综述从试验和计算仿真两个角度，系统阐述了输电塔用复合材料横臂结构的设计改进方法和力学性能研究进展。
