Problems solved by technology

[0004] The technical problem to be solved by the present invention is to combine the carbon fiber into the metal block by mechanical compounding or directly metallurgical, because the carbon fiber has a smooth surface, high inertness, and few chemically active functional groups, so it is chemically compatible with the titanium alloy matrix. Poor physical and chemical compatibility, carbon fiber is difficult to compound into titanium alloy, resulting in low bonding force of the composite material, easy to detach during use, and the disadvantages of reduced tensile and shear resistance of carbon fiber. A carbon fiber reinforced titanium alloy is provided. The preparation method of the alloy composite material, the polyacrylamide of the present invention is used as a raw material to prepare carbon fibers, soaked with organic matter after spinning, then spinning and mixing with the obtained titanium dioxide suspension, loading titanium dioxide on the spinning, and then mixing with metal titanium , obtained after oven drying and calcination

Abstract

The invention discloses a preparation method of a carbon fiber reinforced titanium alloy composite material, and belongs to the field of preparation of composite materials. The cleaning, the disinfection, the sterilization and the enzymolysis are performed for spirogyra and ramie stems; the spirogyra and the ramie stems are put in a fermentation tank for fermenting, and are mixed with ethyl acetate and acetic acid for standing; polyacrylamide is added for mixing and extruding to obtain a cake-shaped carbon fiber material; the cake-shaped carbon fiber material is added in extraction liquid, prepared cotton leaves and chlorophytum comosum, for leaching after the yarn extraction, and is spun for mixing with prepared titanium dioxide turbid liquid; and titanium dioxide is loaded on spun yarns, is mixed with metal titanium, is dried by an oven, and is calcined to obtain the carbon fiber reinforced titanium alloy composite material. The preparation method has the following beneficial effects: the method is simple in preparation process; as carbon fibers are treated, the chemical compatibility and the physical compatibility between the carbon fibers and titanium alloy matrixes are improved; and the obtained product is excellent in quality, is high in bonding force, is not easy to be extracted in use, and is high in material stretching resistance and shearing resistance.

Description

technical field [0001] The invention relates to a method for preparing a carbon fiber reinforced titanium alloy composite material, belonging to the field of composite material preparation. Background technique [0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, researched and developed them one after another, and obtained practical applications. In the 1950s and 1960s, it mainly developed high-temperature titanium alloys for aero-engines and structural titanium alloys for airframes. In the 1970s, a batch of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. develop. Titanium alloys are mainly used to make aircraft e...
