Abstract

The invention discloses a Ti / Al / Cf layered composite material and a preparation method thereof. The invention relates to the Ti / Al / Cf layered composite material and the preparation method thereof, and aims to solve the problem of relatively poor interfacial bonding of the Ti / Al / Cf layered composite material at present. The product consists of a layered core material and a sheath, wherein the sheath is made of a titanium foil of which the thickness is 30-50[mu]m; and the layered core material sequentially comprises a titanium layer and a plurality of repeated laminated units from top to bottom, and each laminated unit sequentially comprises an aluminum layer, a carbon fiber cloth layer, an aluminum layer and a titanium layer from top to bottom. The method comprises the following steps: 1, performing surface treatment on carbon fiber cloth; 2, cleaning surfaces of the titanium foil and an aluminum foil; 3, preparing a prefabricated member; 4, preparing the sheath; and 5, performing vacuum hot pressed sintering. The layered material disclosed by the invention is good in interfacial bonding and high in interfacial strength. The material is prepared by sintering in vacuum, and the preparation process is simple and feasible, and is convenient in operation.

Description

technical field [0001] The invention relates to a preparation method of Ti / Al / Cf layered composite material. Background technique [0002] With the continuous development of science and technology, the industry has put forward increasing requirements for the performance of materials, and it is difficult for a single material to meet the required special or comprehensive performance. On the one hand, structural materials are required to have the characteristics of high strength, light weight, and high temperature stability, and on the other hand, functional materials are required to integrate thermal, chemical, electrical, magnetic and other properties. [0003] With its good mechanical properties, metal matrix composites have attracted the attention of researchers in the field of materials from all over the world. It has high specific strength, specific stiffness, specific modulus and other excellent properties, and can be widely used in automotive and aerospace fields. . ...
