The present invention relates to an under cover for automobiles in which a resin impregnated grid layer is interposed between an upper felt layer and a lower felt layer. According to the present invention, problems of deterioration of workability and human health due to scattering of glass fiber when mounting a vehicle part on a lower part of an automobile, and a problem of exposure of glass fiber due to peeling and breakage of a nonwoven fabric part due to collision of a road foreign matter during driving are solved. Meanwhile, tensile strength, bending strength, and stability of the under cover are improved to prevent durability degradation due to weakness of a mounting part when testing a water pipe line and also the under cover can be recycled.
