Abstract

The invention provides a preparation method of a continuous carbon fiber reinforced aluminum-based composite material. According to the preparation method provided by the invention, the thickness of an aluminum layer adhered to the surface of the carbon fiber can be controlled by adopting a method of adhering curing aluminum powder to the surface of continuous carbon fiber through organogel, so that the content and the spacing of the carbon fiber in a composite material after hot pressing sintering can be controlled, the carbon fiber can be parallelly distributed in an aluminum matrix, and analuminum-based composite material with high carbon fiber content can be prepared. The preparation method disclosed by the invention is low in cost and easy to operate and is capable of realizing industrialized production; the strength of the carbon fiber reinforced aluminum-based composite material obtained through the preparation method provided by the invention is obviously superior to that of the carbon fiber reinforced aluminum-based composite material prepared through an existing infiltration method, and a wide application prospect is obtained.
