基于短切碳纤维表面均匀包覆Cu层工艺的Cf/Cu复合材料制备与表征
|
Abstract:
为制备能够在Cu基体中分散均匀的大体积分数的短碳纤维（Cf）/Cu复合材料，采用电化学法在Cf表面进行了镀Cu处理，用平行Cu片做阴极代替长碳纤维束，得到镀层均匀光洁的镀Cu短Cf。在此基础上，将2 V，30 min条件下的Cf/Cu复合丝直接采用放电等离子烧结（SPS）制备了46vol% Cf/Cu复合材料（试样1），又用Cu粉与未包覆的Cf直接混合再烧结制备了另一种46vol% Cf/Cu复合材料（试样2）。利用XRD和SEM分别研究了Cf/Cu复合丝和Cf/Cu复合材料的物相成分、表面及断口形貌，对Cf原丝、Cf/Cu复合丝以及用2种方式制备的Cf/Cu复合材料进行了力学性能研究。结果表明：Cf/Cu复合丝拉伸载荷-位移曲线上出现了较大幅度的波动，这与其表面镀Cu层受力时发生不连续断裂有关。试样1组织的均匀性及力学性能均优于试样2。与Cu相比，用2种不同方法制备的Cf/Cu复合材料的抗拉强度低于Cu，但屈服强度比Cu高。 To prepare a uniformly dispersed short carbon fibre (Cf)/Cu composite in Cu matrix which contained a large volume fraction of Cf, by an electro-chemical method in the process of Cu plating on the surface of Cf, a parallel Cu fosil was used as cathode instead of long carbon fibre bundle.By which, more homogeneous and smooth Cu-plating short Cf were obtained. Based on that, the 46vol% Cf/Cu composite (sample 1)was prepared directly by spark plasma sintering (SPS) with those Cf/Cu composite filament prepared at 2 V, 30 min. Then non-coated Cf mixed with Cu powder were used to prepare another Cf/Cu composite(sample 2).The phase composition, surface and fracture morphology of Cf/Cu composite filament and the Cf/Cu composites were researched through XRD and SEM. After that, there was a comparison with these samples on the mechanical properties.Results show that the Cu coating creates discontinuous fractures under load, which causes fluctuations in the tensile load-displacement curve of Cf/Cu composite filament. Besides, the uniformity and mechanical properties of sample 1 are higher than sample 2. The tensile strengths of Cf/Cu composites made by two different ways are lower than Cu, but the yield strengths are higher. 国家自然科学基金（51461029）；兰州理工大学红柳青年教师培养计划（201203）
