Embodiment 1

[0029] Example 1: The metal matrix composite material includes 0° direction yarns, 45° direction yarns, 90° direction yarns and 135° direction yarns, and has a square cross section. The yarns are all made of 12K nickel-plated carbon fiber yarns, and the metal materials are made of aluminum. The thickness of the metal matrix composite is 4 mm.

[0030] Specific implementation steps:

[0031] (1) Layer the metal matrix composite CAD model along the Z direction to generate section profile information;

[0032] (2) Apply a layer of release agent on the abutment;

[0033] (3) According to the cross-sectional profile information, print liquid metal on the abutment along the direction of 0° to form a metal groove, then lay the reinforcement material in the metal groove along the direction of 0°, and then place the reinforcement material along the direction of 0° The liquid metal is printed in the direction of 0°, the liquid metal penetrates into the reinforcement material and form...

Abstract

The invention discloses a three-dimensional printing method of a metal-based composite material and belongs to the technical field of formation of composite materials. The method comprises the following steps: laying CAD models of parts of the metal-based composite material along direction Z, and generating section outline information of the parts; respectively printing liquid metal and reinforcing materials layer by layer according to the section outline information; after all layers are printed, obtaining the metal-based composite material by machining. The method is simple in formation process, high in operability and high in designability because the reinforcing material can be randomly orientated according to a design angle.

Description

technical field [0001] The invention relates to a three-dimensional printing forming method of a metal matrix composite material, belonging to the technical field of composite material forming. The invention is mainly used to prepare long-fiber reinforced metal matrix composite materials, the manufacturing process is simple, and the molding quality can be significantly improved and the molding cycle can be shortened. Background technique [0002] Metal matrix composites are composite materials made of metal or alloy as the matrix and various reinforcing materials. Compared with traditional metal materials, metal matrix composites have higher specific strength and specific modulus. Compared with resin-based composite materials, metal-based composite materials are non-combustible, high-temperature resistant, radiation-resistant, non-moisture-absorbing, and have good electrical and thermal conductivity. They are excellent high-temperature materials for aerospace and can be use...
