Thermoplastically deformable composite material comprises a core layer comprising a glass fiber fabric layer (B) that is connected on both sides with a nonwoven fabric layer (A) comprising polypropylene fibers and glass fibers. The core layer is connected to at least one top layer (D) in the form of a fleece comprising polyethylene terephthalate fibers and polypropylene fibers. An independent claim is also included for producing the composite material comprising joining together fleeces D and A and the fabric B, and the fleeces D and A, needling together the two resulting structures and heating the needled structure to 180-210[deg] C, so that the polypropylene is melted and the fibers join together.
