Detailed Explanation of Production Process of Composite Aluminum Honeycomb Panel

Composite aluminum honeycomb panel is suitable for civil construction, automobile decoration, etc. It is an aviation and aerospace material used in the field of civil construction. Using hot press molding technology, due to the high thermal conductivity between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skin are synchronized; there is a small hole on the honeycomb aluminum skin, so that the gas in the plate can flow freely; the sliding installation buckle system will not cause structural deformation during thermal expansion and contraction.

Usually made of 0.02~0.1mm thick aluminum foil sandwich, used to make aluminum honeycomb panels. Usually with thickness 0.03,0.04,0.05. There are two methods of making aluminum honeycomb panel sandwich. One is the molding method: the aluminum foil strips are formed into corrugated strips, and then the corrugated strips are laminated with glue to form aluminum honeycomb panel core blocks. The invention is only applicable to alloy foils with large thickness and high rigidity, or non-hexagonal special aluminum honeycomb panel sandwich cores. The second is the stretching method: first coated with adhesive strips on the aluminum foil, then the aluminum foil is laminated, glued into a laminate, and stretched into an aluminum honeycomb panel core block. Ordinary regular hexagons and square bee latticework are made in this way.

Composite aluminum honeycomb panel tensile method to manufacture aluminum honeycomb panel sandwich core process:

1. Surface treatment of metal foil. Oil treatment before coating, generally using solvent vapor deoiling, alkali washing, etc. At the same time, the aluminum foil can be chemically oxidized, passivated and phosphated to improve the bonding strength and durability of the aluminum foil.

2. Aluminum foil is coated with glue. Glue application includes longitudinal strip glue application and horizontal strip glue application.

3. The superposition and curing of aluminum foil. The glued aluminum foil shall be stacked according to the required number of sheets, and then heated and cured in a hot press or hot press tank.

　　4、夹芯的拉伸成形及加工。这一步骤有两种方案：即加工形状先拉伸，形状先加工后拉伸。composite aluminum honeycomb panelThe shape curvature of the structure adopts the pre-deformation method. First after forming drawing is generally suitable for processing and other cross-sectional shapes or straight busbar shapes of aluminum honeycomb plate core blocks.
