specific Embodiment approach 1
[0012] Specific embodiment one: a kind of method of connecting carbon fiber reinforced aluminum matrix composite material and metal of this embodiment is carried out according to the following steps: 1, the aluminum powder of 54~58 parts by weight, the nickel powder of 8~10 parts Powder and 33~37 parts of copper oxide powder are mixed evenly, placed in the ball mill tank, and the ball is put into the ball at a mass ratio of 5:1. Under the condition of argon protection, the Speed ball milling for 2-3 hours to obtain mixed powder; 2. Press the mixed powder obtained in step 1 into an intermediate laminated compact with a relative density of 60%-80% and a thickness of 1-3mm, and seal it for storage; 3. The intermediate laminated blank is placed between the carbon fiber reinforced aluminum matrix composite material and the metal to assemble a "sandwich" assembly, and then the assembly is clamped and placed in a vacuum furnace, and heated to 500°C under a pressure of 5MPa , and ke...
