Embodiment 1

[0058] This embodiment is to utilize above-mentioned preparation device to prepare a kind of [carbon fiber Industrial pure aluminum] composite material, it is prepared according to the following method:

[0059] S1. Smelting aluminum alloy substrate: In this embodiment, a resistance melting furnace is used to melt industrial pure aluminum. The specific components of industrial pure aluminum are shown in Table 1; The temperature was set at 720°C, and when the industrial pure aluminum ingot was completely liquid, it was kept for 20 minutes to uniform the temperature field of the melt. The industrially pure aluminum melt after smelting is silvery white and has good fluidity. Since the industrial pure aluminum melt is prone to oxidation reaction with air, a dense aluminum oxide film is formed on the surface of the melt, which can protect the inner melt to a certain extent. Therefore, in order to prevent the film from being damaged, the During the holding period, fluctuations in...

Abstract

The invention relates to the technical field of carbon fiber composite reinforced materials, especially a design concept of a synergistically extensible carbon fiber reinforced metal matrix composite material. By folding the carbon fiber cloth into a corrugated shape and implanting it into the metal matrix, the corrugated carbon fiber cloth The undulating direction is consistent with the plastic rolling direction; in the subsequent plastic rolling deformation process, the corrugated carbon fiber cloth is coupled with the aluminum alloy matrix for cooperative extension and deformation, so as to realize the matching of the ductility of the carbon fiber cloth reinforcement phase and the metal matrix. The invention also relates to special equipment for embedding carbon fiber cloth in a corrugated form into a metal matrix and a method for preparing a synergistically extensible carbon fiber reinforced metal matrix composite. In the present invention, the carbon fiber cloth of the inner layer exists in the metal matrix in a corrugated form, so that in the subsequent thermoplastic rolling process, the carbon fiber with the corrugated structure can be coupled with the aluminum alloy matrix to achieve cooperative extension and deformation, thereby overcoming the lack of ductility of the carbon fiber The disadvantages brought about.
