| 摘 要： | 以碳纤维的三维编织架构为增强体,经镀铜预处理后,置于铝合金熔体中施加压力成形,得到三维编织碳纤维增强铝基复合材料。探究大气和氩气气氛下不同三维纤维架构挤压成型的复合材料的界面特征与结构。通过拉伸试验及扫描电镜检测,对材料性能进行表征。结果表明:紧密编织的三维编织碳纤维较宽松结构的三维编织碳纤维,与铝合金基材的浸润性和相容性更好,铝合金在与三维编织碳纤维复合后拉伸强度与硬度均提升。

| Abstract: | A 3 D braided carbon fiber reinforced Al-matrix composite was obtained by placing carbon fiber 3 D braided structure pretreated with copper in aluminum alloy melt and applying pressure forming. The interface characteristics and structures of the composites with different 3 D fiber structures extruded in atmospheric atmosphere and argon atmosphere were investigated. The tensile test and scanning electron microscopy were used to characterize the properties of the materials. The results show that the3 D braided carbon fiber with tight braided structure has better wettability and compatibility with aluminum alloy substrate than the 3 D braided carbon fiber with loose structure,and the tensile strength and hardness of aluminum alloy improve after the composite with 3 D braided carbon fiber. |
