摘　　要：以苎麻纤维织物SiC陶瓷为生物模板,通过腐蚀、敏化、活化、施镀等工艺镀金属镍,后经高温真空环境熔渗金属Cu,制备出了苎麻纤维织物SiC/Cu复合材料。通过物理性能、显微组织等测试分析,研究了镀镍时间对样品的各项性能和微观形貌的影响。结果表明,镀镍时间超过30min,随镀镍时间增加,苎麻纤维织物SiC预制体的密度增加、开口气孔率降低、体积密度变化不大;苎麻纤维织物SiC陶瓷独特有序的生物结构和金属镍层的存在共同改善了金属Cu的熔渗效果。The ramie fiber fabric SiC/Cu composite material was prepared by etching,sensitizing,activating and plating nickel regarding the SiC ceramics as the biological template,and then infiltrating the metal Cu under high temperature vacuum environment.The effects of nickel plating time on the properties and microstructure of the samples were investigated by physical properties,microstructure and other tests.The results show that with the nickel-plated time increasing,the density of SiC ceramic preforms increases,the open porosity decreases,and the bulk density does not change much when the nickel plating time exceeds 30 min.The unique and orderly biological of ramie fiber SiC ceramics and the metal nickel layer together improves the infiltration effect of the metal Cu.
