摘要: 利用红外光谱、液相色谱等分析技术研究了T700碳纤维/聚三唑树脂预浸带在不同储存时间与条件下物理化学特性的变化规律。研究表明,聚三唑树脂预浸带应在冷藏或冷冻环境下储存,以延长预浸带的使用期,满足大型构件制备要求。

Abstract: The physicochemical behavior of prepreg tape of carbon fiber(T700)/polytriazole resin at different storage time and conditions was studied by IR and GPC. With injcreasing storage time, the molecular weight of the resin, insoluble species content, and triazole ring content increased, but the volatile component decreased. The prepreg tape should be refrigerated or frozen in order to extend the use period for large scale preparation.

Key words: carbon fiber, storage characterization, polytriazole, prepreg, quality control
