“…So, Cf in these tests were cut to 2 mm in length: because of a lack of Cf wetting by molten aluminium and the formation of brittle materials, Al4C3, between Cf and the matrix at high temperatures, which were easily broken to influence the combination of Cf and the matrix [11], Cf surface should be modified to ensure the compatibility between Cf and the matrix material. The modification process for Cf reinforcement has been investigated elsewhere [12].…”

“…The pre-treatment process included: burning to get rid of any glue, acidulating, neutralising, sensitising, activating, and reducing. Then, an electroless copper-plating layer was uniformly coated on the pre-treated Cf surface and its deposition controlled to avoid influencing the composition of the aluminium alloy matrix [12].…”

Short modified carbon fibres (Cf) were applied to reinforce a 2024 aluminium alloy to investigate the effect of Cf content on the mechanical properties of an aluminium matrix composite. As Cf volume fraction increased, the composite had more pores and defects while Cf were distributed uniformly throughout and combined well with the matrix. Hot extrusion reduced pore and defect frequency, and made Cf aligned in the extruded direction. These factors, such as Cf volume fraction, distribution, interface combination with the matrix, pores and defects mainly induced by Cf adding, had a great influence on the mechanical properties of such aluminium matrix composites. In comparison with the matrix material, the elastic properties of the prepared composite were improved while its plasticity decreased. The results show that Cf surface modification, component control, and optimum heat treatment should be investigated further to improve the property of short Cf reinforced aluminium alloy composites.

“…Li et al regulated the wettability between the carbon fiber and aluminum matrix by Ni-coated carbon fiber, and successfully prepared a composite material in which the carbon fiber was completely impregnated [7][8][9]. Liu et al found that the presence of copper coating would hinder the diffusion of carbon elements into aluminum matrix, which can effectively inhibit the interface reaction between carbon fiber and aluminum matrix [10]. Therefore, the coating was prepared on the carbon fiber surface has an important influence on the properties of Cf/Al composites.…”

In order to prevent the copper coating on the carbon fiber surface from oxidizing and falling off, the tin coating is plated on the surface of copper-coated carbon fiber. In this paper, the copper-tin composite coating with different thicknesses of tin coatings were successfully prepared by electroless plating. The results show that with the increasing of electroless tin plating time, the thickness of the copper-tin composite coating increases. The test results of the bonding force between the composite coating and the carbon fiber show that the coating bonding force is the best when the thickness of composite coating is between 1.31 μm and 1.55 μm. This is due to the formation of copper-tin intermetallic compounds preventes direct contact between the copper coating and oxygen, which can effectively inhibit the oxidation of the copper plating layer, thereby making the plating layer less likely to fall off. However, the excessively thick tin coating would increase the internal stress of the coating, and promote the generation of cracks on the surface of the composite coating, which would cause the composite coating to fall off. This research will provide new ideas for the preparation of high-performance copper plating on the surface of carbon fiber, and provide an important theoretical and practical basis for the application of copper coatings.
