智通财经APP获悉，国泰海通发布研报称，维持玻璃纤维行业"增持"评级。覆铜板龙头集体布局26年高 端份额的争取，带动近期特种电子布采购框架上修。同时，传统电子布在织布机转产影响下继续提价的 确定性较高。薄布的紧缺特性更加明显。综合推荐边际客户突破或产能成本占优的特种电子布与普通电 子布龙头企业。 此轮产业关注更多在低介电二代布，尤其关注份额潜力大覆铜板企业的采购框架 近期市场针对玻纤电子布材料关注度聚焦二代布，判断基于：1)谷歌TPU下一代产品基本框架有望升级 成以M8级别覆铜板配套二代布，对于二代布是新的增量需求;2)英伟达链条二代布使用量的确定性还是 较高。从二代布需求格局上看，三家头部覆铜板企业的采购框架最受关注，包括增速力求进一步突破客 户和份额的生益科技，在ASIC链不断争取增量的台光电子，以及伴随既有客户有望升级的松下。相比 二代布而言，一代布2026年供应安全性更乐观;代表产业趋势的石英布在逐步解决供应链，可加工性， 成本等短期局限，等待产业化更进一步更清晰的信号。 "挤出效应"加剧供需缺口，普通电子布价格趋势乐观 风险提示：AI下游需求拓展不及预期;电子布产能格局变化。 国泰海通主要观点如下： ...
