摘要

摘要: 以硼酸为保护剂, 通过在C-Cu复合丝表面涂覆一层硼酸试剂, 有效地解决了高温复合时镀铜层的氧化难题, 并通过XRD、 SEM和拉伸强度测试全面考察了硼酸的影响。实验结果表明, 硼酸的浓度为1.0%时铜镀层的氧化程度很小, 炭纤维在复合材料中分散均匀且与基体铝结合良好, 1.0%的硼酸用量对复合材料的力学性能没有任何影响。

Abstract: Boric acid was used as a protecting agent on C-Cu fiber surface to solve the oxidizing problem while compounding C-Cu/Al composites. The effects of boric acid on the performance of the composites were analyzed through SEM, XRD and tensile tests. The results show that carbon fibers coated with copper are little only a oxidized when pretreated with 1.0% boric acid solution. These carbon fibers in the composites are finely dispersed and have good cohesion with the matrix. Besides, such an amount of boric acid does no harm to the mechanical properties of the composites.
