摘要

在碳纤维表面镀上一层金属铜镀层，用硼酸对其进行防氧化处理，采用机械搅拌法制取C/Al复合材料。利用扫描电镜、能谱分析和X射线衍射等手段对液态机械搅拌法制备的碳纤维增强铝基复合材料的界面微观结构进行了分析，结果表明，碳纤维表面镀铜，既可有效解决碳纤维与铝的润湿性问题，又可有效地阻挡碳纤维与铝的过度化学反应。硼酸作为保护剂，有效地解决了高温复合时镀铜层的氧化难题。Cu/Al界面生成大量的CuAl2金属间化合物，C-Cu/Al界面为混合界面：C/Cu界面和C/Al界面。

Abstract

Firstly

copper was deposited on carbon fibers.Boric acid was used to protect copper from oxidation and stir casting process was adopted to prepare short carbon fibers reinforced aluminum matrix composites.The microstructure of the interface in the composites was analyzed by using SEM，XRD and EDX.The results indicated that wettability was improved and excessive chemical reaction was restrained between carbon fiber and aluminum when copper was deposited on carbon fibers.Boric acid was used as a protecting agent to resolve the copper oxidation problem while compounding C/Al composites.There were large quantities of intermetallic compounds formed at the Cu/Al interface.And the C-Cu/Al interface was a mixed interface of C/Cu and C/Al.
