COMPOSITE MATERIAL FOR THERMAL OR ACOUSTIC INSULATION

Composite material (10) and manufacturing process of a composite material (10) for realizing thermal and/or acoustic insulation in vehicles, buildings or systems comprising an overall flat plate-like basic form with at least one insulation material (2) and at least one functional layer connected to the insulation material (2) in the form of a drainage structure (1), wherein the drainage structure (1) forms an air and liquid-permeable layer of the composite material (10), wherein the insulation material (2) comprises a soft foam or a bulk nonwoven based in particular on PET, PP, PANox, cotton or a mixture thereof, wherein the drainage structure (1) is formed unevenly on the side facing the insulation material (2), in particular with punctually protruding points or parts for fastening to the insulation material (2), and on the opposite side has a means (3, 4) for abrasion protection on the outside of the composite material (10).
