Wheel arch liner for a vehicle comprising at least a structural porous fibrous layer extending longitudinal in a curved shape with a front end and a rear end wherein the porous fibrous layer is at least partly corrugated wherein the corrugations comprises alternating grooves and ridges and wherein at least the ridges are situated at the inner side of the curve shaped porous fibrous layer and wherein the grooves and ridges extend longitudinal transversal to the longitudinal curved shape.

A filter core and manufacturing method thereof, the manufacturing method has the following steps: adhering a wavy filtering sheet and a flat filtering sheet, pressing the filtering sheets, and rolling the filtering sheets. A part of peaks of the wavy filtering sheet are pressed to lean toward a same side. In particular, two sides of a first end sealing adhesive layer are pressed. Thus, the first end sealing adhesive layer is concentrated, such that the glue is uniformly spread to the two sides. Besides, the pressing on the two sides makes the two sides of the first end sealing adhesive layer adhered securely, thereby preventing the wavy filtering sheet from rebounding upward and forming bubbles. Thus, the first end sealing adhesive layer can be formed with less quantity of glue, which accelerating the cooling and raises manufacture efficiency.

A wing includes an upper wing skin, a lower wing skin, and a wing rib positioned between the upper wing skin and the lower wing skin. The wing rib includes: a corrugated composite web comprising a wave pattern and a first fitting coupling said corrugated composite web with one of said upper wing skin and said lower wing skin.
