A study on Honeycomb Sandwich Panel and its Expansion Machine(HCXM)

An avant–garde study on honeycomb panel expansion machine to fabricate honeycomb sandwich panel. This panel consists of two thin sheets in which a light weight thick core is placed in between them. Usually, aluminum & magnesium are considered for the fabrication of honey comb panel for economic considerations. Titanium alloys are considered for specific applications such as aerospace structures. Conventionally, the honeycomb panels are manufactured by the processes such as welding, brazing, forming. Nowadays, adhesive bonding also considered for manufacturing of honeycomb sandwich panels. During the process, honey comb core is in the form of HOBE then it will expanded to required cell size by using machine known as honeycomb sandwich panel expansion machine (HCXM). Initially, HOBE form of honeycomb panel is made up with paper model. And top and bottom platen is also made up with paper model. To ensure the operation feasibility, then the study has been carried out on the fabrication of aluminum alloys using HCXM as per ASTM standards.
