A sandwich panel is a structure made of three layers: low density core inserted in between two relatively thin skin layers. This sandwich setup allows to achieve excellent mechanical performance at minimal weight. The very high rigidity of a sandwich panel is achieved thanks to interaction of its components under flexural load applied to the panel: core takes the shear loads and creates a distance between the skins which take the in-plane stresses, one skin in tension, the other in compression.

Honeycomb sandwich panel has been proven as the most efficient sandwich design with respect to mechanical performance and weight. Aerospace and aircraft industry uses the honeycomb structures as they meet the tough requirements of related applications. The use of honeycomb sandwich design in more common applications has been more limited due to the batch wise manufacturing processes and hence relatively high production costs.

Quantam sandwich panels are delivered as prefabricated finished panels which give you the option to choose between different insulation materials, profiles, insulation dimensions, surfaces and a range of colours. The panels are compact, all-in-one elements, consisting of an outer, solid envelope, a layer of insulation and an inner liner.


Application

Sandwich panels are used in applications where high structural rigidity and low weight are required. An evident example of use of sandwich panels is aircraft, where mechanical performance and weight saving is essential. Other applications include packaging (e.g. fluted polypropylene boards of polypropylene honeycomb boards), transportation and automotive as well as building & construction.

Honeycomb structures

Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. The cells are often columnar and hexagonal in shape. A honeycomb shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties.

Composite material

A Composite material (also called a composition material or shortened to composite, which is the common name) is a material made from two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter, or less expensive when compared to traditional materials. More recently, researchers have also begun to actively include sensing, actuation, computation and communication into composites, which are known as Robotic Materials.
