CELLULAR STRUCTURE MULTILAYER MATERIAL Russian patent published in 2020 - IPC B32B3/12 B21D47/00 

FIELD: machine building.

SUBSTANCE: invention relates to automotive industry and domestic appliances and can be used, in particular, for production of car mats and car decor elements or as floor mats for shoe cleaning, as well as at the entrance to the building. Disclosed are 2 embodiments of multilayer material of cellular structure. In compliance with first embodiment, multilayer material of cellular structure is proposed, which includes unidirectional, multi-row, interconnected cells of cone-shaped shape arranged on face side and having rhombus, hexagonal cell, irregular hexagon and other in their cross-section. At that, the cone top of the cells is made in the form of a hemisphere, and the back side is equipped with attachment units to the component elements of the product. In another embodiment, the multilayer material of the cellular structure includes unidirectional, multi-row, interconnected cells of cone-shaped shape, placed on the front side and having in their section a rhombus, a hexagon (honeycomb), an irregular hexagon and the like, wherein the apex of the cone of cells is made in form of a hemisphere. Besides, it is equipped with lengthwise or transverse ribs extending on 2–3 mm, passing along joint of cells and arranged with specified pitch or with cells protruding on 2–3 mm ribs, arranged in staggered order.

EFFECT: technical result of proposed technical solution of task is reduction of dust and dirt accumulation in top of cells and facilitation of material cleaning.
