    Effect of Infiltration Copper or Aluminium on Flexural Strength of C/C Composite Materials

      摘要
    • 摘要: 采用三点弯曲法研究浸渗铜和铝对碳/碳复合材料弯曲性能的影响,分析了复合材料弯曲断裂前后的组织形态,并对弯曲性能进行了比较和探讨.结果表明：碳/碳+渗铜和碳/碳+渗铝材料的抗弯强度分别达到88,196 MPa,大于碳/碳复合材料的77 MPa:金属铜、铝对碳润湿性的差异使碳/碳+渗铜界面结合强度弱于碳/碳+渗铝界面结合强度,这导致碳/碳+渗铝抗弯强度远大于碳/碳+渗铜的抗弯强度.碳/碳+渗铜和碳/碳+渗铝抗弯强度都达到TB/T 1842.1-2002铁道部行业标准电力机车粉末冶金滑板性能要求.

       

      Abstract: The flexural strength of C/C composite materials which infiltrated by copper or aluminium was investigated through the three-point bending method.The results indicate that the flexural strength of C/C+Cu and C/C+Al is 88,196 MPa respectively,which is higher than the C/C composite that is 77 MPa.Because of the interface joined intensity of C/C+Al is better than C/C+Cu,the flexural strength of C/C+Al is much higher than the C/C+Cu.Flexural strength of the C/C+Cu and C/C+Al have been up to even exceed the standard TB/T 1842.1-2002 for the slides made via powder metallurgy for electric locomotives.
