Abstract

The invention relates to a Ti / Al laminar composite material and a preparation method thereof, in particular to a fiber-reinforced Ti / Al laminar composite material and a preparation method thereof, and aims to solve problems that preparation technologies of existing laminar composite materials are complex and mechanical properties are low. The composite material comprises a laminar core material and a sheath; the sheath is made of a Ti plate or a stainless steel plate; the laminar core material comprises a Ti layer and multiple layers of repeated laminated units sequentially from top to bottom; and the laminated units comprise an Al layer, a fiber cloth layer, an Al layer and a Ti layer sequentially from top to bottom. The preparation method comprises steps as follows: Ti foil, Al foil and fiber cloth are used as raw materials, or the Ti foil, Al-containing powder and the fiber cloth are used as raw materials, and the fiber-reinforced Ti / Al laminar composite material is prepared. The material and the method have the advantages as follows: the technology is simple, the method is convenient to operate, and the bending property ranges from 420 MPa to 510 MPa. The method is mainly used for preparing the fiber-reinforced Ti / Al laminar composite material.

Description

technical field

[0001] The invention relates to a Ti / Al layered composite material and a preparation method thereof. Background technique

[0002] With the rapid development of the aerospace industry, the performance requirements for high-temperature structural materials are getting higher and higher, not only high temperature resistance and oxidation resistance but also high specific strength and specific stiffness are required. Carbon fiber reinforced aluminum matrix composites are widely used in many fields represented by aerospace due to their low density, good electrical and thermal conductivity, high specific modulus, high specific strength, high temperature dimensional stability and high temperature strength. . Titanium and titanium alloys have good comprehensive properties such as low density, high specific strength, high temperature resistance, corrosion resistance, non-magnetic, sound transmission, shock resistance and vibration resistance, which open up broad app...
