| 摘 要： | 以稀土氧化物CeO2为添加剂,研究CeO2对镀镍碳纤维增强铝合金基复合材料碳纤维的分布、气孔率以及力学性能的影响,利用扫描电镜分析和拉伸力学性能检测等探讨了CeO2在镀镍碳纤维增强铝合金基复合材料中的行为。结果表明:CeO2能够使碳纤维均匀分布在复合材料中,而不产生分层及团聚;而且能够降低复合材料的气孔率,使轧制态复合材料的抗拉强度、屈服强度分别提高23%和26%。

| Abstract: | The influence of CeO2 as the addition agent on the distribution of carbon fiber,porosity and mechanics of the aluminum alloy matrix composites reinforced with Ni-coated carbon fibers was investigated.The behavior of CeO2 in the aluminum alloy matrix composites reinforced with Ni-coated carbon fibers was discussed by scanning electron microscopy(SEM) and tensile test.The results show that CeO2 can make the distribution of carbon fiber even in the composites,not laminated,not agglomerated,and can reduce the porosity of composites,and increase the tensile strength by 23% and the yield strength by 26% of the composites in the rolling form. |
