Embodiment 1

[0058] This embodiment is to prepare a [carbon fiber Industrial pure aluminum] composite material, which is prepared as follows:

[0059] S1, smelting aluminum alloy matrix: In this embodiment, a resistance melting furnace is used to smelt industrial pure aluminum. The specific composition of industrial pure aluminum is shown in Table 1. The specific melting process is: putting the industrial pure aluminum ingot into the resistance melting furnace for smelting. The temperature is set to 720°C. After the industrial pure aluminum ingot is completely liquid, keep it for 20 minutes to even the temperature field of the melt. The industrial pure aluminum melt after smelting is silvery white and has good fluidity. Because industrial pure aluminum melt is prone to oxidation reaction with air, a dense aluminum oxide film is formed on the surface of the melt. The aluminum oxide film can protect the internal melt to a certain extent. Therefore, in order to prevent the film from being damag...

Abstract

The invention relates to the technical field of carbon-fiber composite reinforcement materials, in particular to a design concept of a carbon-fiber-reinforced metal-matrix composite capable of achieving synergistic elongation. Carbon fiber cloth is folded into a ripple shape to be embedded into a metal matrix, and then the rippling direction of the ripples of the carbon fiber cloth is consistent with the plasticity rolling direction; and in the subsequent plasticity rolling deformation process, the ripple-shaped carbon fiber cloth is coupled with the aluminum alloy matrix to achieve synergistic elongation deformation, and then the reinforcement phase of the carbon fiber cloth is matched with the ductility and malleability of the metal matrix. The invention furthermore relates to a specialdevice used for introducing the carbon fiber cloth into the metal matrix in a form of ripples and a method for preparing the carbon-fiber-reinforced metal-matrix composite capable of achieving synergistic elongation. According to the carbon-fiber-reinforced metal-matrix composite and the preparing device and method, the carbon fiber cloth at the inner layer exists in the metal matrix in a form ofripples, so that in the subsequent thermoplasticity rolling process, carbon fibers of the ripple-shaped structure can be coupled with the aluminum alloy matrix to achieve synergistic elongation deformation, and thus shortcomings caused by the lack of ductility and malleability in the carbon fibers are overcome.
