A part of a motor vehicle is made from plastic material and includes at least one wall configured to be welded to a bodywork element. The wall includes at least one protruding element defining a weld surface configured to form a point of contact with said bodywork element. The part includes, around the protruding element, at least one stress relief area for relieving stresses experienced by the protruding element.

Disclosed herein are a vehicle door trim board that is less likely to break due to partial use of an impact resistant resin and a door trim using such a vehicle door trim board. A vehicle door trim board includes a reinforcing part made of an impact resistant resin containing a polyolefin resin, a polyamide resin, and a compatibilizer, wherein the compatibilizer is a modified elastomer having a reactive group that reacts with the polyamide resin. The door trim includes: the vehicle door trim board; and a surface skin layer provided on a design surface side of the vehicle door trim board.

A method produces a fiber composite component according to which a fiber arrangement having carbon fibers as reinforcing fibers is arranged on a carrier material having a fibrous material in order to form a structure. A covering layer having a non-conductive material is arranged on the structure. The carbon fibers are arranged largely in the load path direction of the fiber composite component to be produced, and regions of the fiber composite component to be penetrated by electromagnetic signals and/or waves are configured such that they are largely free of carbon fibers.

A panel assembly for a vehicle made of different materials with different coefficients of thermal expansion according to various exemplary embodiments of the present invention includes: an external panel 10, an internal panel 20 having the circumference bonded to the circumference of the external panel 10, and made of a material having a coefficient of thermal expansion different from a coefficient of thermal expansion of the external panel 10, and at least one deformation absorption panel 30, 40 connected to at least one of the external panel 10 and the internal panel 20 on the circumferences of the external panel 10 and the internal panel 20, and for absorbing an amount of thermal deformation according to a change in temperatures of the external panel 10 and the internal panel 20 when the external panel 10 and the internal panel 20 are thermally deformed.

A vehicle door assembly, having a first frame component including a window frame for a window opening and two opposing lateral frame for defining a frame cut-out and forming a sill portion connecting the two lateral frame portions to one another, a second frame component for strengthening the window frame, the second frame component fixed on the first frame component, and a door module carrier formed from an organosheet and at least partially closes the frame cut-out. The door module carrier forming an edge portion fixed to the sill portion in a longitudinal direction of the sill portion. The organosheet is a supporting structural component and an edge portion thereof is reinforced by a reinforcing structure injection-moulded onto the organosheet and the edge portion thereof strengthens the sill portion of the first frame component where no portion of the second frame component is provided.

Structural liner (20) of a motor vehicle hatchback (10) having an outer face (22) oriented towards the outside of the vehicle and an inner face (24) oriented towards the inside of the vehicle when the hatchback (10)) is assembled on the latter, and at least one groove (23) borne by one of the two faces (22, 24), the groove (23) forming a zone of mechanical weakness able to facilitate the execution of an opening (28) within the structural liner (20).

A method for producing a reinforcing component from different materials, wherein, in a first step, the component is produced in a first mould by plastics injection-moulding with foaming of the plastics material used and by reducing large cross sections of the component by insert parts of the same plastics material, wherein, in a second step, at least one type of fibre is wound around the component, and wherein, in the third method step, the component as a whole is overmoulded with plastic of a second plastics material in a second mould.

A method of manufacturing a plastic glazing of a tailgate of a vehicle, the method comprising: injecting a first material into a molding apparatus to form a first component of the plastic glazing, wherein the first component comprises a panel of the plastic glazing; injecting a second material into the molding apparatus to form a second component of the plastic glazing, wherein the second component combines with at least the first component, wherein at least a portion of the first component and the second component comprises a transparent cover of a molded light assembly; and injecting a third material into the molding apparatus to form a third component, wherein the third component combines with at least the first component.

A vehicle bodywork panel is formed by an outer wall supported by a structural lining. The structural lining is produced by molding a plastic or composite material. The structural lining may include stiffeners arranged to provide said bodywork panel with a given amount of mechanical strength. One or more added connection elements connect separate fastening points disposed on the structural lining and each end of each of the connection elements is inserted into a housing disposed on a stiffener. The rigidity of the connection elements is adapted to suppress a vibration response of the stiffeners. The housing and the connection element may form a flush-mounted connection.

A method of forming a trim panel is provided. The method including the steps of: placing a non-woven mat of material in a heating press; heating the material to a predetermined temperature; applying a decorative film to a first surface of the heated material to create a bilaminate; placing the bilaminate layer into a cavity of a tool such that the decorative film is facing the cavity; heating the cavity; and injecting a thermoplastic resin into the tool such that the thermoplastic resin is adhered to a second surface of the material, the second surface being opposite to the first surface. Also disclosed is the trip panel formed by the foregoing method.
