以冷模压及热挤压两种成型方法，采用相同的压粉，制备了２种纯炭材料及２种炭－铜纤维复合材料。测试了该４种材料的电阻率、肖氏硬度、抗压强度、抗折强度、冲击韧性、气孔率及体积密度，观察了材料的显微组织结构、讨论分析了不同成型方法对所制材料性能的影响。
Two kinds of molding methods, cold pressing and hot extrusion, were used to prepare two kinds of pure carbon materials and two kinds of carbon-copper fiber composites by using the same pressure powder. The electrical resistivity, Shore hardness, compressive strength, flexural strength, impact toughness, porosity and bulk density of the four materials were tested. The microstructure of the materials was observed. The effects of different forming methods on the properties of the materials The impact of performance.
