FIELD: construction.
SUBSTANCE: invention relates to construction, in particular to an inner layer containing zigzag wood elements and a multilayer composite including an inner layer, as well as methods of their production. Inner layer suitable for a multilayer composite material contains at least one coating layer and an inner layer. Inner layer comprises wood elements contain zigzag sheet sections, herewith a sheet zig-section of the element together with an adjacent sheet zag-section of the element form a common rib between them in order to form a zigzag wood element. Zigzag elements are arranged in the inner layer so, that two such ribs of the two different elements intersect at an angle other than zero and are rigidly connected to each other at the point of intersection. In one embodiment the zigzag wood element can be stuck to a planar wood element for the zigzag wood element in the form of a sandwich to be enclosed with two planar wood elements; or for the planar wood element to be enclosed with two zigzag wood elements in the form of a sandwich.
EFFECT: technical result is improvement of the structure strength.
