FIELD: textile, paper. ^ SUBSTANCE: invention refers to porous sheets on base of thermo-plastic polymer reinforced with fibre. Material of the composite sheet consists of a permeable middle layer including discrete natural fibres bound with thermo-plastic resin; also the said permeable middle layer has density within range of approximately from 0.1 g/cm3 to 1.8 g/cm3. Notably, the said permeable middle layer includes surface zone. ^ EFFECT: facilitating ecological advantages such as pure burning and recycling, also reduced weight of material. ^ 25 cl, 1 dwg |
