Abstract
A fibrous vehicle underbody shield and method for manufacturing the same is provided. A binderless core of non-woven fibrous material defines first and second surfaces of the fibrous vehicle underbody shield. The second surface of the fibrous vehicle underbody is opposite the first surface such that the first and second surfaces are separated by a final product thickness. The first and second surfaces include at least one molded contour that gives the first and second surfaces a non-planar shape. The non-woven fibrous material of the binderless core includes a plurality of fibers that are mechanically entangled with each other and have a coating that withstands a heat exposure of 200 degrees Celsius. The fibrous vehicle underbody shield includes a latex impregnation. The latex impregnation is disposed on at least one of the first and second surfaces and penetrates the non-woven fibrous material of the binderless core an impregnation distance.
