Multilayer fabrics

Multilayer fabrics 

Multilayer fabrics

Multilayer fabrics consist of two or more fabric layers woven together.

Reinforcement materials from a thickness of 0.15 mm to several millimetres can thus be achieved. For example, the finishes may exhibit a fine, smooth structure on the one side and a coarser structure on the other side.

The woven connection of the individual layers not only improves the peel strength (no shearing of the individual fabric layers) but also the breaking characteristics of the laminate.

Multilayer fabrics exhibit outstanding draping properties even at mass per unit areas of up to 800 g/m². Spherical (ball-shaped) components can be processed easily and efficiently.
