Problems solved by technology

[0003] But so far, the preparation methods for manufacturing carbon fiber reinforced titanium alloy composites can be classified into two categories: solid-phase method and liquid-phase method. The production of parts and components, but the production cycle is long, and it is not suitable for industrial mass production of thin plates and other profiles; although the solid-phase method can continuously produce composite materials such as plates, it generally requires the primary product of composite materials-composite wire, and the complex production process increases. In addition, the reinforcing fiber is generally a brittle material. Under the action of huge pressure, the plastic deformation will cause great damage to the reinforcing fiber, which is not conducive to giving full play to the performance advantages of the reinforcing fiber.
