国际复材 20251230 摘要 AI 电子布需求激增，谷歌等公司大量应用二代布，预计 2026 年需求不 低于 5,000 万米，2027 年可能达到 1.几亿米，国际复材积极扩产应对 市场需求。 国际复材作为玻纤龙头，新增年化产能 6,000 万米生产线，处于全球领 先地位，逐步进入一代布和二代布的批量供给阶段，并计划新增约 50 个干锅，使二代布产能翻倍。 公司已为规划项目筹划资源匹配，包括新增订购资金及贵金属采购，目 前贵金属储备充足，并已订购 500 多台织布机，将于 2026 年下半年逐 步交货。 干锅全部转向生产二代布后，每月供给量可达数十万米，客户结构从以 生益科技为主扩展到红河、台光等企业，生益科技仍是当前最紧迫需求 方之一。 二代布干锅法良率约为拉丝环节 70%-80%，整体拉通计算 50%- 60%。公司交付能力尚未完全满足客户需求，如生益科技预计 2026 年 月需求量将达 60-100 吨。 Q&A 近期玻纤行业的变化和趋势如何？ 近期玻纤行业呈现出积极变化，特别是在 AI 电子部件的升级趋势方面。二代布 被认为是 2026 年缺口最大的品种，主要用于 NV 的 GB300 Swit ...

方案升级趋势明确，看好 PCB 产业链高弹性 20151223 摘要 议主要集中在电信号传输效率处于及格线，但差损指标不满意。虽然考虑过用 DF 值更低的 PDFE 覆铜板，但由于制造难度大、良率和稳定性低，最终决定继 续使用马九材料制作正胶背板。 正胶背板未来出货节奏如何？ 预计 2025 年第一季度会有少量样品用于 GTC 会议展示。到 2026 年下半年开 始小批量出货，到 2027 年将实现大批量出货。目前预期整个行业供需到 2027 年会处于紧平衡状态，高端激光钻孔设备拉货时间延长至一年半以上， 这使得产能爬坡相对较慢。因此，PCB 行业价格和利润率有望维持高水平直到 2027 年。 AI 服务器背板方案预计 2025 年 2 月定案，2026 年 3 月 GTC 会议展示， 2026 下半年小批量出货，2027 年大批量出货。技术难点在于层数多、 对齐钻孔难度大及高温铜浆烧结技术，当前争议点为电信号传输效率的 差损指标不理想。 菲利华石英电子布已从测试转向小批量生产，价格提升至 250-280 元/ 米，预计 2026 年出货 1,000 万米，贡献约 10 亿人民币业绩增量。公 司是全球唯一全产 ...
