Definitions

  • Hydra-formed metal sections may have curved three-dimensional geometry.
  • reinforcing the section or component is very difficult because the location of the hydra-formed section that is critical and decides the overall performance of the component, is often the section located at a major discontinuity "notch" or curvature .
  • a further object of this invention is to provide techniques for reinforcing such a beam.
  • the beam is a hollow structure.
  • a pre-molded foam core is inserted into the hollow structure spaced from at least one inside wall of the hollow structure.
  • a polymer is pumped in and around the foam core insert so that after curing the polymer bonds to the inside wall of the structure.
  • the structure is a hydra-formed metal section, such as a vehicle control arm assembly.
  • the pre-shaped foam insert is preferably made of a lightweight material to minimize the weight of the final laminate beam formed by the invention.
  • Figure 2 is a cross-sectional view taken through Figure 1 along the line 2-2.
  • the present invention is particularly useful for reinforcing hollow sections or structures, which are of curved geometry and/or located at locations, which are relatively inaccessible.
  • the hollow structure is a metal section, such as a hydra-formed metal section with curved three-dimensional geometry.
  • An example of such section is a control arm assembly, wherein it is desired to reinforce the control arm beam.
  • the critical portion which requires reinforcement in order to maximize the overall performance of the component is often the portion at a major section discontinuity "notch" or curvature.
  • Figure 1 illustrates an automotive control arm assembly beam 10 made of a hydra-formed metal shell 12 of conventional size and shape and structure such as including through holes 14 and end walls 16. As can be seen the shell 12 has a three dimensional geometry which is non-uniform from end wall to end wall and which is curved.
  • a preformed foam core 18 is inserted into the hollow or cavity of shell 12.
  • Core 18 is spaced away from at least one inside wall of the hollow shell 12 and is shaped to extend along at least one side of the shell .
  • Core 18 functions to locate a reinforcing polymer 20 within the hollow shell so that after curing the polymer will bond to and reinforce the inside wall of the shell.
  • Core or insert 18 is made of a lightweight pre-shaped or preformed material such as urethane, phenolic or expanded polystyrene.
  • the polymer 20 would be pumped in and around the foam core 18 so as to be located in the space between core insert 18 and the inner wall of shell 12.
  • Polymer 20 is then cured such as being heat cured or ambient temperature cured.
  • polymer 20 is bonded to the inner wall of shell 12 and to foam core 18 to function as a structural foam.
  • the polymer or structural foam may be, but is not necessarily an expandable foam.

Abstract

Un profilé stratifié tridimensionnel (10) est formé en disposant un insert constituant une âme en mousse préformée (18) dans une section métallique hydroformée (12) à géométrie tridimensionnelle incurvée. Un polymère de renforcement (20) est pompé dans/ et sur le pourtour de l'âme en mousse, de manière à être adjacent à la paroi intérieure de l'enveloppe. Le polymère se lie à la paroi intérieure de l'enveloppe sur le polymère durci.
