Abstract
The invention relates to a composite tube manufacturing method, which comprises the following steps: firstly, a metal mould core is provided, and a layer of metal inner tube is deposited on the outer surface of the metal mould core by nano metal by using an electrochemical process, wherein, the nano metal is not absorbed by the metal mould core; secondly, a composite material layer with reinforced fiber and thermosetting resin or a plastic material layer is molded on the outer surface of the metal inner tube; thirdly, the metal mould core is drawn out to form a rough blank; and fourthly, the rough blank is cut. The composite tube manufactured by adopting the composite tube manufacturing method has an extremely thin inner metal layer, and not only the inner wall is smooth and abrasion resistant, but also the overall weight is light and the strength is high.
