Embodiment 1
[0018] In this embodiment, the carbon fiber reinforced phenolic epoxy composite material T300 / 648 and the 6061 aluminum alloy plate are welded with the dimensions of 100*50*1mm.
[0019] This embodiment includes the following steps:
[0020] S1. Machining the carbon fiber composite material plate and the aluminum alloy plate to obtain the plate to be welded;
[0021] S2. Use 400-mesh sandpaper to polish the contact surfaces of carbon fiber composite material 1, titanium foil 2, copper sheet 3 and aluminum alloy plate 4, and then put them into an acetone solution with a purity ≥ 99.8% for ultrasonic cleaning for 10 to 15 minutes to remove surface oil. and other sundries, make sure the surface is clean;
[0022] S3, such as figure 1 As shown, the carbon fiber composite material 1, titanium foil 2, copper sheet 3 and aluminum alloy plate 4 are stacked sequentially from bottom to top. In order to ensure the close contact between each material, a clamp can be used to form an asse...
