PANEL HAVING HIGH STRUCTURAL STRENGTH, METHOD OF ITS MANUFACTURING AND DEVICE TO MANUFACTURE SUCH PANEL

摘要

FIELD: construction.;SUBSTANCE: panel comprises a leaf (3), arranged between two layers of coatings (2), made of fibrous structures (21), which are attached by means of a layer-forming or a connecting material, for instance, a polymer (22), a binder, a foamed polymer. The leaf usually contains foamed materials, thick felts, powder materials, semifluid materials, etc. Fibres (7) from fibrous structures (21) are pulled along one or more directions of inclination relative to layers of coatings (2) and usually by means of needle piercing, into the leaf (3), in particular, into foam plastic plates (4), which represent the leaf. The fastening material is also used to fix the pulled fibres (7) to do mutual fixation of leaf (3) components and coating layers (2).;EFFECT: invention may be used for economically efficient manufacturing of especially stable composite panels with a high number of leaf components, layers of coatings and alignment of pulled fibres of fibrous structures.;20 cl, 18 dwg
