The invention relates to a composite for an acoustic component having at least one carrier layer and an electrospun membrane which is arranged on the at least one carrier layer, wherein the electrospun membrane is formed of superimposed fibers while a pore structure is being designed. The pore structure of the composite is designed such that the composite has a water column of at least 1 m and an air permeability of 5 L/m*s. Furthermore, the invention relates to a method for producing a composite for an acoustic component, in which a carrier layer is provided and on the carrier layer a membrane is designed according to the electrospinning method, wherein the membrane is produced of superimposed fibers with a defined pore structure.

Composite membrane and method for producing a composite membrane

An optoelectronic film assembly, has a first flat electrode layer, a second flat electrode layer as a counter electrode to the first flat electrode layer, a dielectric layer between the electrode layers and an active layer provided next to the dielectric layer and arranged between the electrode layers and made of an electroluminescent material. To this end, the first and/or the second electrode layers are implemented to be translucent and TCO-free, particularly ITO-free, by using a woven fabric comprising electrically conductive fibers.
