The present disclosure is directed at a moldable layered structure that is particularly suited for vehicular underbody applications. The structure is generally comprised of at least one layer of needled staple polyester fibers and at least one layer of spunbond polyester fibers. A method for forming a multilayer material and the multilayer material so formed, which is particularly suitable for vehicle underbody applications. The method includes providing a first non-woven layer of spunbond polyester wherein said polyester comprises at least 50% by weight of an ester of an aromatic carboxylic acid and the first layer is present at a thickness of 0.1 mm to 2.0 mm and at a basis weight in the range of 25 g/m2 to 150 g/m2. |
