Embodiment 1
[0026] A method for preparing a high-load and high-heat-resistant braided fiber-reinforced aluminum matrix composite material, comprising the following steps:
[0027] (1) Prepare the fiber prefabricated body. The fiber prefabricated body is made of polyacrylonitrile-based carbon fiber M40 braided body produced by Toray Company. The fiber preform is then placed in a packaging mold. Among them, the encapsulation mold is made by vertically fixing the fiber preform with a high-temperature-resistant graphite gasket, then making an outsourcing mold according to its size, and then putting the fiber preform fixed by graphite into the mold together. A liquid inlet is left in the packaging mold for subsequent feeding of liquid carbon dioxide and liquid metal.
[0028] (2) Degumming: at 20°C, 5.6×10 6 Under the condition of Pa, feed liquid carbon dioxide into the packaging mold so that the liquid carbon dioxide completely submerges the fiber preform, close the liquid inlet, and let it...
Embodiment 2
[0034] A method for preparing a high-load and high-heat-resistant braided fiber-reinforced aluminum matrix composite material, comprising the following steps:
[0035] (1) Prepare the fiber prefabricated body. The fiber prefabricated body is made of polyacrylonitrile-based carbon fiber M40 braided body, and its braided structure is a 2.5D dimensional braided body with shallow cross-bending links. Then place the fiber preform in a packaging mold adapted to the size of the fiber preform in the same preparation method as in Example 1. The encapsulation mold is provided with two liquid inlets, one is provided with a riser pipe for subsequent liquid metal inlet, and the other is provided with a liquid infusion pipe for liquid carbon dioxide inlet.
[0036] (2) Degumming: Place the packaging mold and the ZL301 aluminum alloy in the upper and lower chambers of the vacuum pressure infiltration device in the manner of Example 1, and connect the infusion tube with the outside world. Fi...
Embodiment 3
[0042] A method for preparing a high-load and high-heat-resistant braided fiber-reinforced aluminum matrix composite material, comprising the following steps:
[0043] (1) Prepare the fiber prefabricated body. The fiber prefabricated body is made of polyacrylonitrile-based carbon fiber M40 weaving body, and its weaving structure is a deeply cross-linked 2.5D dimensional weaving body. Then place the fiber preform in a packaging mold adapted to the size of the fiber preform in the same preparation method as in Example 1.
[0044] (2) Degumming: at 20°C, 5.6×10 6 Under the condition of Pa, feed liquid carbon dioxide into the packaging mold, so that the liquid carbon dioxide completely submerges the fiber preform, close the liquid inlet, and let it stand and soak for 24 hours.
[0045] (3) Expansion: Open the liquid inlet, first release to normal pressure, part of the liquid carbon dioxide volatilizes, and the other part of the carbon dioxide forms dry ice; then heat to sublimate...
