Definitions
- the invention relates to a motor vehicle composite component and a method for its production.
- the automotive composite part is in particular a visible in the installed state automotive composite component with an integrated electrical connectivity, for example, a car door with integration of functional elements such as windows, door lock, speakers, lamps, switches for mirrors, switches for a roof, Ventilation ducts, airbag etc.,
- A-pillar or B-pillar a supporting vertical column (A-pillar or B-pillar), or
- CONFIRMATION COPY a trunk lining or interior lining.
- a vehicle door of conventional construction has a steel support system, which is covered on the outside by a metal sheet.
- an aggregate support system is made, which is usually made of metal or synthetic material separately, and in the support system are electrical or electronic elements such as windows, lock, speakers, etc. by screwing, gluing, riveting, clipping etc attached.
- an inner lining of textile, leather or plastic is applied and fixed.
- a plastic foam element is mounted, which serves the thermal and acoustic insulation and can be seen on its surface with an additional skin or even with a prefabricated laminate layer.
- the invention has for its object to provide a method for producing a motor vehicle composite component of the type mentioned, with which a corresponding composite component can be produced in a simplified manner.
- a corresponding motor vehicle composite component is to be created.
- This object is achieved with regard to the method in a first alternative by a method having the features of claim 1.
- first of all plastic particles are introduced into a mold cavity of a molding tool, where they are connected to one another while supplying heat energy to form a particle foam.
- the mold is adjusted by changing the mold cavity and then injected a thermoplastic material forming at least one support element and / or at least one fastening element in the mold cavity, wherein the thermoplastic material is connected at least in a materially bonded manner with the particle foam.
- the mold is again adjusted by changing the mold cavity and then a molten metal is injected into the mold cavity, whereby at least one electrical conductor and / or at least one metallic fastener are formed.
- thermoplastic material is injected to form at least one support element and / or at least one fastener in a mold cavity of a mold. Thereafter, the mold is adjusted under the end of the mold cavity and then plastic particles are introduced into the mold cavity and there, with the supply of heat energy to a particle foam connected to each other, wherein the thermoplastic material is connected at least in a material-locking manner with the particle foam. Subsequently, the mold under changes of
- thermoplastic resin is first injected into the mold cavity and then the plastic particles are introduced into the mold cavity and it becomes a Particle foam formed, which is connected to the thermoplastic material.
- cohesive connection is a
- stiffening elements are introduced into the mold cavity before the introduction of the plastic particles and then embedded in the particle foam.
- the stiffening elements may be, for example, plastic fibers and / or natural fibers and / or at least one net of plastic or metal or at least one lattice of plastic or metal.
- prefabricated fasteners are introduced before the introduction of the plastic particles in the mold cavity and then embedded in the particle foam.
- prefabricated connecting elements are introduced into the mold cavity before the introduction of the thermoplastic material and then embedded in the thermoplastic material.
- the connecting elements may be, for example, screws and / or threaded rods and / or clips.
- the particle foam is formed with a closed-pored surface.
- the vehicle composite component is produced in an integrated particle foam metal injection method, wherein a particle foam, a thermoplastic material, a molten metal and optionally
- the method combines the previously separate and temporally spaced steps in a single operation. Separate fasteners made of different materials are no longer required and the connection functions are integrated into the composite component, whereby the subsequent assembly processes are shortened and simplified. In addition, assembly errors are avoided, resulting in significant cost savings.
- the composite component has a low weight and at the same time a high absorption capacity against noise and against the action of external forces and additionally has a very good thermal insulation.
- the particle foam not only fulfills a filling function, but also represents an elementary component of the composite component, which fulfills supporting and filling functions, serves for fastening, has a temperature and sound absorbing effect and also fulfills protective, covering, decoration and haptic functions.
- the particle foam serves as an electrical insulator.
- all electrical conductors and necessary metal fasteners are introduced by the metal injection process in the particle foam and / or the thermoplastic material, so that the subsequent retraction of power cables or the equipment of the Ver Bundbauteils with clips, screws, etc. is no longer necessary.
- thermoplastic material By injecting the thermoplastic material can form functional elements, controls or frame structures.
- the introduced stiffening elements serve to reinforce the composite component, wherein fibers or fiber composites can also be injected simultaneously with the thermoplastic material.
- the automotive composite component for achieving the above object has a carrier made of plastic particle foam, which is materially connected to support elements and / or fasteners made of a thermoplastic material, and at least one electrical conductor track and / or at least one metallic fastener.
- a motor vehicle composite component 10 has a carrier 11 made of a plastic particle foam, which is formed at least on its upper side with a closed-pored surface 16.
- the carrier 11 is materially connected to support elements and / or fastening elements 12 made of a thermoplastic material. On the carrier 11, at least one conductor track 13 is formed, which cooperates with metallic fastening elements 14, 15.
