Create the honeycomb core by selectively bonding layers
Honeycomb type core adds nothing to the stiffness of a structural composite panel construction other than to make the two faces work as a unit. The stiffness, EI , of a given construction is therefore based entirely upon the physical properties and dimensions of the two faces. Honeycomb cores are used in the fabrication of lightweight structures. The core material is typically ’sandwiched’ between skins and plywood, aluminum, FRP composite material, steel, granite, solid surface materials, paper etc.
Honeycomb cores are formed by selectively binding layers of scored material and then expanding the stack to produce a regular cellular structure. Alternative routes for their manufacture include corrugation accompanied by bonding and the extrusion of thermoplastics. Honeycomb fiberglass composite panels are used extensively for flooring in both military and commercial aircraft. Typically, commercial aircraft flooring is about 1cm thick and is made of glass or carbon fibre reinforced epoxy skins with a Nomex honeycomb core.
Thus, since no difference in pressure is made between the inside and the outside of the sandwich panel, the front and rear surface layers are prevented from being broken or removed from the honeycomb core. As a result, the sandwich panel with high durability can be received. Thus the panels are widely used in many industrial and commercial applications of the day-to-day life such as light trailer panels. Thus, each panel having some different characteristics suitable for that unique environment. The panel itself is reversable and symmetrical so don’t worry about installing it backward.
