摘要
通过在铝基体中添加合金元素Mg,并改变Mg的含量和浸渗时间制备Cf/Al复合丝,研究了基体合金化和浸渗时间对碳纤维微观组织和力学性能的影响。结果发现,碳纤维的抗拉强度随着Mg含量的增加而增加,但Mg含量超过8.5%后,抗拉强度反而降低。碳纤维的抗拉强度随着浸渗时间的增加则逐渐降低,在前8min下降趋势明显,随后下降趋势趋于平缓。
Effects of Mg addition and infiltrating time on microstructure and mechanical properties of carbon fibre reinforced aluminum matrix composites were investigated. The results show that the tensile strength of the composites is increased with increasing in Mg addition, however, with Mg content more than 8.5%, the tensile strength of the composites prepared is decreased. The tensile strength of the composites is decreased with the increase of infiltration time, and the declining tendency exhibits sharp in the first 8 min and then slow.
