Embodiment 1
[0041] Aluminum honeycomb panels were prepared by brazing with 1mm thick 3003 aluminum alloy as the panel and 0.2mm thick composite aluminum foil (3003 aluminum alloy as the core material and 4045 aluminum alloy as the cladding layer) as the honeycomb core.
[0042] 1) Make the aluminum honeycomb core fixture, process the stainless steel plate into four frame bars, such as figure 2 The aluminum honeycomb core fixture frame bar 6 shows that the length, width, and thickness of the frame bar are: 90mm×8mm×6mm, and an M2 threaded hole is opened at both ends of each frame bar, and the distance between the two threaded holes is 76mm to ensure that the center of the fixture The size of the aluminum honeycomb core that can be fixedly assembled is 68mm×68mm. use figure 2 Bolts 4 for fixing the aluminum honeycomb core fixture and nuts 5 for fixing the aluminum honeycomb core fixture connect and fix the four frame bars end to end in sequence, that is, they are assembled into an alumin...
Embodiment 2
[0050] Example 2: Brazing Prepare an aluminum honeycomb panel with a 1.5mm thick composite brazing plate, a core material of 3003 aluminum alloy, a cladding layer of 4043 aluminum alloy as a panel, and a 0.15mm thick 1060 aluminum foil as a honeycomb core. The specific preparation process is the same as in Example 1.
