摘要/Abstract

摘要： 以进口的HM40-3K碳纤维和国产的BSCHM40-3K碳纤维为研究对象,采用SEM对碳纤维的表面形貌进行表征,通过表面/界面张力仪对碳纤维的接触角、表面能和浸润性进行分析,然后对HM40-3K/环氧TDE-86、BSCHM40-3K/环氧TDE-86固化吸胶过程吸胶系统的设定和最终制件含胶量进行分析。试验结果表明,碳纤维集束性越大越分散,接触角越小,表面能越大,表面能极性分量越大越有利于树脂的浸润,固化过程中树脂越不容易被吸出来。参照HM40-3K/环氧TDE-86固化过程的吸胶公式给出了BSCHM40-3K/环氧TDE-86的吸胶公式,并发现了支持该吸胶公式成立的重要规律。

Abstract: The HM40-3K carbon fiber produced by the foreign company and the BSCHM40-3K carbon fiber made by China were selected as research objective. The scanning electron microscope (SEM) was applied to characterize the surface morphologies and roughness of these carbon fibers. The contact angle, surface energy and wettability of the two type fibers were investigated by surface tension-meter. Experiment of HM40-3K/epoxy resin TDE-86 and BSCHM40-3K/epoxy resin TDE-86 bleeders′ system to analysis the epoxy resin content of the products. The experimental results showed that the wettability was closely related to the tow size of carbon fiber, contact angle, surface energy and the polar components of surface energy. The wettability was increased with the tow size of carbon fiber and rose from the surface energy and the polar components of surface energy. In addition, the wettability became better by decreasing the contact angle. As a result, the better of the wettability, the epoxy resin was more difficult to absorb by bleeder materials. According to the resin content′s formula of the HM40-3K/epoxy resin TDE-86, the formula of the BHM3-3K/epoxy resin TDE-86 was summarized and an important rule supporting this formula was found.

Key words: carbon fiber, surface energy, wettability, bleeder technology
