Manufacturing method of carbon fiber profiled bodies for aerospace, aviation and fire fighting

A manufacturing method of carbon fiber profiled bodies for aerospace, aviation and fire fighting, comprising following steps:

• S1, melting and solidifying a fusible material into a core mould of a required profiled body, where a melting point of the fusible material is smaller than a melting point of a carbon fiber cloth;
• S2, uniformly winding the carbon fiber cloth outside the core mould to form a carbon fiber shell, and opening a drainage hole at a non-working surface of the carbon fiber shell;
• S3, heating the carbon fiber shell of the carbon fiber cloth to melt the core mould, and discharging a melted liquid of the core mould through the drainage hole;
• S4, cooling the carbon fiber shell to a normal temperature, enabling a non-stressed wall of the carbon fiber shell to be in contact with liquid nitrogen, and prefabricating a layer of molten metal on a stressed wall of the carbon fiber shell;
• liquid nitrogen provides good cooling protection for the carbon fiber shell during a casting process of the molten metal, avoiding thermal damage to the carbon fiber shell caused by the molten metal;
• S5, placing the carbon fiber shell prefabricated with the molten metal in an airtight container, increasing a pressure in the airtight container so as to firmly adhere the molten metal onto a surface of the carbon fiber shell;
• and
• S6, allowing the molten metal to be cooled and moulded, taking out the carbon fiber shell and refining a metal surface of the carbon fiber shell thereby obtaining a carbon fiber profiled body.
