The invention refers to a vehicle rim (1) with a rim body (2) made of fiber composite material, comprising a first subpreform (3) at a first axial end and a third subpreform (5) at the opposite second axial end, wherein a second subpreform (4) is arranged between the first subpreform (3) and the third subpreform (5), wherein the second subpreform (3) engages into a front connecting cavity (6) formed by the first subpreform (3) as well as also into a rear connecting cavity (7) being formed by the third subpreform (5). The invention also refers to a method for the production of a vehicle rim (1) with a rim body (2) made of fiber composite material, wherein an NCF material (19) comprising carbon fibers, glass fibers and/or aramid fibers is created respectively for the formation of a first subpreform (3) for a first axial end of the rim body (2) and of a third subpreform (5) for the opposite axial end of the rim body (2) with a connecting cavity (6, 7), respectively, wherein a second subpreform (4) made of a same or a similar NCF material (19) is inserted into the connecting cavity (6 and/or 7) and is fixed thereat.
A vehicle rim with a rim body made of fiber composite material, comprising a first subpreform at a first axial end and a third subpreform at the opposite second axial end, wherein a second subpreform is arranged between the first subpreform and the third subpreform, wherein the second subpreform engages into a front connecting cavity being formed by the first subpreform as well as also into a rear connecting cavity being formed by the third subpreform, wherein the first subpreform and/or the second subpreform and/or the third subpreform includes an NCF material, and the vehicle rim further includes a roving bundle which is attached to the first subpreform and/or the third subpreform, and wherein the vehicle rim further includes a seam which sews the roving bundle on the NCF material.
A method for the production of a vehicle rim with a rim body made of fiber composite material, wherein an NCF material comprising carbon fibers, glass fibers and/or aramid fibers is created for the formation of a first subpreform for a first axial end of the rim body and of a third subpreform for the opposite axial end of the rim body with a connecting cavity, wherein a second subpreform made of the NCF material is inserted into the connecting cavity and is fixed thereat, wherein the method further includes attaching a roving bundle on the NCF material of the first subpreform and/or the NCF material of the third subpreform, and wherein the roving bundle is sewn on the NCF material of the first subpreform and/or the NCF material of the third subpreform.
A method for the production of a vehicle rim with a rim body made of fiber composite material, wherein an NCF material comprising carbon fibers, glass fibers and/or aramid fibers is created for the formation of a first subpreform for a first axial end of the rim body and of a third subpreform for the opposite axial end of the rim body with a connecting cavity, wherein a second subpreform made of the NCF material is inserted into the connecting cavity and is fixed thereat, wherein the method further includes attaching a roving bundle on the NCF material of the first subpreform and/or the NCF material of the third subpreform, and wherein the first subpreform is twice as heavy per square meter than the third subpreform.
