The invention relates to a method for producing a support element for a means of transport, wherein the method comprises: —providing a polypropylene/natural fiber mat (106), wherein the mat (106) has a basis weight of less than 1150 g/m2, wherein the polypropylene/natural fiber mat (106) comprises a first type of natural fibers, —preheating the mat (106), —placing the mat (106) in a mold (100), wherein the mold (100) has a rib-shaped cavity (112), —pressing the mat (106) into a predefined form by the mold (100), so that the thickness of the mat (106) after the pressing is less than 1.5 mm—immediately and directly after the pressing, insert molding the mat (106) by injecting a polypropylene-containing material into the rib-shaped cavity, wherein the insert molding has the effect that the material forms stiffening ribs (200) that are integrally bonded with the mat (106), —demolding the mat (106) comprising the stiffening ribs (200).
