Technology of regular folded structures

Folded structures are 3D regular relief configurations obtained from a plane by folding along a pattern.

Structures, made from specific material and having folded structure are called folded structures.

Advantages of folded cores:

A possibility to remove moisture from the inner part of sandwich panel
High strength and stiffness
High impact resistance
Fine acoustic properties
A possibility to manufacture structures from a wide range of materials
Simple processing scheme for cores manufacturing without additional operations of bonding, cutting and impregnation of the core

Basic principles of various folded structures development, classification.

Basic structure is a plane Z-crimp. Modifying Z-crimp, various shapes of folded cores with new properties may be obtained: with cellular structure, single or double curvature, curvilinear enveloping surfaces and areas of contact for bonding to the skins, and other properties.
