IN-DEPTH ON SANDWICH PANELS

SIMILAR TO I-BEAMS : Sandwich panels are comparable to an endless I-beam in the sense that when subjected to bending , the flanges carry in-plane compression and tension loads while the web carries shear loads .
In a sandwich panel , the sandwich skins or laminates are like the flanges while the core is like the web .
Like an I-beam , when the skins are further apart , the structure gains more proportional stiffness .
A thicker core achieves the same , but it also provides an overall low density , resulting in a high stiffness-to-weight ratio .
In a sense , sandwich panels can be compared to I-beams
CNC routers are typically used to machine sandwich panels for caravans
