Abstract:
1. A method for manufacturing a copper alloy composite, comprising: a step of shaping a copper alloy part by machining from a casting or an intermediate material; a chemical etching step of immersing the shaped copper alloy part in an acidic aqueous solution containing an oxidant; a surface hardening step of immersing the chemically etched copper alloy part in a strongly basic aqueous solution containing an oxidant; a step of coating the hardened surface of the copper alloy part with an uncured epoxy resin; a step of adjusting a prepreg of a fiber-reinforced plastic by adjusting a size of the prepreg; a step of applying the prepreg to the coated side of the copper alloy part; and a step of positioning the prepreg and the copper alloy part, and heating the prepreg and the copper alloy part while holding them down, to cure the epoxy resin component.
