Definitions

  • the invention relates to a composite component from two or more profiles and a method for its production, in which at least one profile with a free
  • End adjoins the second profile or is immersed in the second profile, characterized in that reinforcing elements are attached in the area of the connection point of the profiles, which form a positive connection with the profiles, and that the profiles are joined together by thermoplastic material which is injection-molded or shrunk on in the area of the connection point are connected.
  • the invention relates in particular to a method for joining profiles and plates by creating high-strength and highly rigid composite components, in particular in a plastic-metal hybrid construction, the joining of the semi-finished products and the production of the composite components being achieved simultaneously by a shaping process of thermoplastic molding compositions.
  • the invention also relates to a method for connecting semi-finished products by creating highly resilient joining areas in hybrid construction.
  • the process produces composite components that consist of high-strength and high-rigidity components such as Made of steel or composites, which are joined with the help of a thermoplastic, held in position and additionally supported in the form of ribs or solid walls.
  • High-strength connections of heavy-duty beams, profiles, plates, etc. can often be found in vehicle or mechanical engineering. Beams made of steel or aluminum are predominantly used, which are welded or glued together in the joining areas. To further stiffen the connection points, also referred to below as nodes, struts are integrated or cast nodes, eg aluminum die-cast, are used. Another option is the use of semi- made of composite (long fiber reinforced plastic). These are usually connected to each other by laminating node elements, which also consist of composites.
  • the invention is therefore based on the object of creating joining methods with nodes of the type mentioned at the outset, which both enable high-strength and highly rigid connections of supports and plates and also allow economical joining of semi-finished products and component components to components.
  • the manufacture of the composite components should take place with high dimensional accuracy and reproducibility.
  • a particular task is the collapse of thin-walled profiles with a wall thickness of 0.5 to, due to the injection pressure
  • the invention relates to a composite component made of two or more profiles, in which at least one profile adjoins the second profile with a free end or immersed in a second profile, characterized in that reinforcement elements are attached in the area of the connection point of the profiles, which form a positive fit with the profiles, and that the profiles are connected to one another by thermoplastic material which is injection-molded or shrunk on in the area of the connection point.
  • the reinforcing elements are e.g. Sheets or die-cast parts made of high-strength material.
  • the high-strength materials can be steel, aluminum, magnesium, ceramics, thermosets or long-fiber reinforced plastics, composites or plastics reinforced with technical textiles.
  • An unreinforced or reinforced or filled plastic e.g. based on polyamide (PA), polyester, especially polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyolefin, especially polypropylene (PP), polyethylene (PE), styrene-acrylonitrile copolymer, in particular
  • PA polyamide
  • PET polyethylene terephthalate
  • PBT polybutylene terephthalate
  • polyolefin especially polypropylene (PP), polyethylene (PE), styrene-acrylonitrile copolymer
  • ABS Acrylonitrile-styrene-butadiene copolymer
  • PC polycarbonate
  • PPO polypropylene oxide
  • PSO polyphenylene sulfide
  • PPS polyimide
  • PEEK polyketone syndiotactic polystyrene
  • Profiles in the sense of the invention are, for example, open or closed profiles made of plastic or metal (preferably metal, e.g. steel, aluminum, magnesium) with any cross section. Closed profiles with a round or rectangular cross section or open U-profiles are preferred.
  • the profiles preferably have a wall thickness of 0.3 to 1.5 mm, particularly preferably 0.5 to 1.2 mm.
  • the reinforcement elements are used as highly rigid connecting components in the form of, for example, clips, rings and half-shells, the shape of which is adapted to the profiles (semi-finished products) and component components to be joined and in particular with the aid of struts and / or preferably with further support plates are additionally supported. You will see the profiles and profiles to be joined other component parts.
  • the reinforcement elements serve to reinforce and stiffen the connection point and are designed so that they form-fit with the semi-finished products and component components to be joined.
  • the reinforcement elements are provided with additional supporting walls, which make it more difficult, particularly in the case of an abutting profile, to kink the connection point.
  • a composite component is particularly preferred in which a one-piece reinforcing element is provided at the connection point of the profiles, into which the profiles in front of the
  • thermoplastic Injection molding of the thermoplastic is inserted or inserted.
  • thermoplastic component is arranged as a connecting material with the aid of a shaping process in such a way that it holds the components (profiles and or plates) which are butting against one another in a form-fitting manner but which are otherwise loosely connected as well as the reinforcing elements themselves in position. This can be done by partially or completely enclosing the reinforcing elements.
  • the power transmission from one component to the other takes place via the high-strength components of the reinforcing elements.
  • optionally integrally formed ribs or by filling gaps - which e.g. are formed by individual support plates - with the thermoplastic component an additional increase in the strength of the composite components is achieved, since bulging or kinking of struts and support walls of the reinforcing elements only occurs with higher loads.
