Abstract
The low-cost large-size fiber-reinforced titanium-based composite material provided by the invention is composed of coated continuous reinforcing fibers, titanium-based amorphous solidified structure and titanium alloy. Lay the selected reinforcing fiber on the titanium-based base metal foil with single-sided grooves, and lay the low-melting-point titanium-based alloy foil on the non-grooved side of the titanium-based base metal foil. According to the required thickness of the plate, Stack the prefabricated body, then place the prefabricated body in a hot-press furnace, apply a certain pressure, heat it above the melting point of the low melting point titanium-based alloy foil strip, and keep it for a period of time, then lower it to a certain temperature range, keep it for a period of time, and finally Cool slowly to room temperature to obtain a fiber-reinforced titanium matrix composite. The method has the advantages of simple process and high production efficiency, and helps to quickly realize the preparation of large-scale fiber-reinforced titanium-based composite materials at low cost.
Description
technical field [0001] The invention belongs to the preparation technology of metal-based composite materials, and relates to a method for preparing continuous fiber-reinforced titanium-based composite materials. Background technique [0002] Continuous fiber reinforced titanium matrix composites have high specific strength, specific stiffness, excellent creep resistance and fatigue resistance, and are considered to be one of the ideal lightweight structural materials. Skins, ribs of hypersonic vehicles, and compressor blades, impeller rings, turbine shafts and stator blades of high-thrust ratio aero-engines have good application prospects, and have become the preferred choice for hypersonic vehicles and new-generation aero-engines and aircraft. One of the key new materials. [0003] At present, the main methods for preparing fiber-reinforced titanium-based composite materials and their components are: [0004] (1) Foil-fiber-foil method: the fibers are cross-woven with me...
