通过在碳纤维及钼粉末表面化学镀铜的方法,解决了碳纤维与钼粉化学相容性差的问题,完成了碳纤维表面化学镀铜及钼粉表面化学镀铜工艺方法及试验参数的确定。采用粉末烧结后轧制成型制备复合材料,并分析了碳纤维在钼粉中的含量对该复合材料力学性能的影响。结果表明:所制备的含碳纤维1wt%的复合材料板材,抗拉强度达425 MPa,与纯钼板材相比,抗拉强度提高57%。
Through the method of electroless copper plating on the surface of carbon fiber and molybdenum powder, the problem of poor chemical compatibility between carbon fiber and molybdenum powder is solved, and the method of chemical copper plating on surface of carbon fiber and electroless copper plating on molybdenum powder and the determination of test parameters are completed. The composite material was prepared by powder sintering and then the effect of the content of carbon fiber in the molybdenum powder on the mechanical properties of the composite was analyzed. The results show that the tensile strength of the prepared composite sheet with 1wt% carbon fiber is 425MPa, which is 57% higher than pure molybdenum sheet.
