本文在探讨碳纤维—铜(CF/Cu)复合材料制造工艺的基础上,对其弯曲强度进行了测定并对断口进行了观察和讨论。制造方法采用首先在碳纤维(CF)上进行化学镀,而后电镀、热压。结果表明,在CF预处理和镀覆合适的条件下,可以得到界面结合较好、均匀连续的镀铜复合丝。热压应选择不破坏该结合状态和不压断纤维的条件下进行。结合状态的不同引起了两种不同的断裂方式,进而影响到复合材料的强度。CF/Cu复合材料的弯曲强度与纤维含量(V_f)有关,但并不随V_f作单调增加。 Based on the discussion of the manufacturing process of carbon fiber-copper (CF / Cu) composites, the bending strength was measured and the fracture was observed and discussed. The manufacturing method uses chemical plating on carbon fiber (CF) first, then electroplating and hot pressing. The results show that under the proper conditions of CF pretreatment and plating, copper clad composite wires with good interfacial bonding and uniform continuity can be obtained. Hot pressing should be selected without destroying the bonded state and without breaking the fiber. The combination of different states caused by two different modes of rupture, thereby affecting the strength of the composite material. The flexural strength of CF / Cu composites is related to fiber content (V_f) but not monotonically increasing with Vf.
