Method for laminating a tubular film
09731488 · 2017-08-15 · ·

The invention refers to a method for laminating a tubular film (1) preferably manufactured by means of blown film (co-) extrusion with a material capable of absorbing resin or liquids, wherein the tubular film (1) is laminated over its entire perimeter with several layers (10, 11, 12, 13; 20, 21, 22; 30, 31) overlapping or positioned directly opposite one another on their front sides containing material capable of absorbing resin or liquids, so that essentially there are no areas left along the perimeter of the tubular film (1) not covered by the laminated layers (10, 11, 12, 13; 20, 21, 22; 30, 31). The invention also refers to a tubular film laminated in such a way and to various applications.

20210187820 · 2021-06-24 · ·

The invention relates to a method for continuously producing an embossed web (2) from a primary web (3) having a surface face (3A) and an opposite back face (3B), wherein the primary web (3) is subjected to an operation for embossing the surface face (3A) using a heated embossing cylinder (5), the method being characterised in that the embossing operation comprises at least a first step of compressing the surface face (3A) of the primary web (3), said primary web (3) being in contact with the surface of the heated embossing cylinder (5) on at least one portion (Pc) of the perimeter of the latter, using a compression band (6) in surface contact with the back face (3B) of the primary web (3).

Reinforced Composites and Methods for Their Manufacture

Disclosed herein are, for instance, reinforced composites comprising an airlaid mat comprising a natural fiber component; and a resin dispersed within the airlaid mat; wherein the reinforced composite has a natural fiber volume fraction of 20 vol % to 80 vol %, by volume of the reinforced composite. Also disclosed herein are methods of making reinforced composites. For instance, disclosed herein are methods comprising forming a preform comprising: heating an airlaid mat to a temperature of from 40 C. to 200 C., the airlaid mat comprising a natural fiber component and a binder fiber component; and compressing the airlaid mat at a pressure of from 100 psi to 1200 psi; and impregnating the preform with a resin to form a reinforced composite.
