Definitions

  • the invention relates to a component arrangement, comprising a first component and a second component, wherein at least one component has a plurality of preforms.
  • preforms For weight-optimized and reduced-speed production, different preforms with different wall thicknesses and layer structures are required. These preforms are infiltrated in a subsequent process step with the plastic or resin forming the matrix, for example in a resin transfer molding tool. Because the contiguous component assemblies are made in one shot, preform overlaps are necessary.
  • the one-sided or one-sided preform overlap entails the disadvantage that a strong S-impact is required, which causes a large loss of function of the component.
  • the present invention has the object to provide a simplified component assembly, with which the disadvantages of the prior art are overcome. Furthermore, it is a particular object of the invention to specify a component arrangement which is distinguished in the connecting region of the two components by high mechanical characteristics.
  • the invention proposes a component arrangement comprising a first and a second component, wherein at least one component has multiple preforms. Furthermore, a preform of the second component can overlap a plurality of preforms of the first component in the connection region of the two components. Instead of a single-cut preform overlap, a two- or multi-section preform overlap is created, thereby increasing the overlap areas, ie the areas where preforms of a component are in contact with preforms of a second component. This improves the mechanical characteristics of the component arrangement, so that the component arrangement can absorb higher forces.
  • the components may be formed as fiber-reinforced components with a matrix of thermosetting or thermoplastic material in which reinforcing fibers of carbon, glass, aramid and / or basalt are embedded.
  • the components may be structural components for vehicles, which are formed from a plurality of preforms.
  • Structural components for the purposes of this invention may be, in particular, side members, A-, B-, C-, D- pillar reinforcements, roof hoops, side frames inside or outside, ring bearers, end wall, tunnels, bottom plate and / or reinforcements of the side sills.
  • the first component is an A pillar of a vehicle and the second component is a roof frame of a vehicle.
  • Each of these components may be formed from one or more preforms.
  • the A-pillar may be constructed in two parts, with an inner shell and an outer shell, each shell comprising at least two preforms.
  • the A-pillar has a four-layer structure, through which a large contact surface in the overlapping portion can be realized.
  • the roof frame can be constructed in several parts, and at least have an inner shell and an outer shell. Each of these shells may, in turn, have one or more preforms which can be brought into contact with the preforms of the A-pillar in the overlapping section.
  • 1 is a side view of a side frame
  • Fig. 2 is a sectional view of Fig. 1 along the section line A-A according to the prior art
  • Fig. 3 is a sectional view taken along section line A-A of Fig. 1 according to the present invention.
  • FIG. 1 an assembly of a side frame is shown by way of example.
  • the geometry is intended to be illustrative only and not limiting the present invention.
  • the side frame 10 has an A-pillar 1 1, which is connected at its upper end to the roof frame 12.
  • the connection is according to the prior art as shown in Fig. 2, formed.
  • the A-pillar is constructed with two shells, with an outer shell 11a and an inner shell I i i.
  • the roof frame 12 is also constructed with two shells, with an outer shell 12a and an inner shell 12i. All trays are made of fiber-reinforced plastic material.
  • the individual shell elements overlap each other, touching each other at a contact surface.
  • the A-pillar 1 is also constructed with two shells with an outer shell and an inner shell.
  • the outer shell is in turn formed from two preforms 11a1 and 1a2.
  • the inner shell also comprises two preforms 11 i1 and 11i2.
  • the roof frame 12 is also constructed with two shells with an outer shell 12a and an inner shell 12i, which are each formed from a preform.
  • the preforms of the A pillar 11 partially overlap the preforms of the roof frame 12.
  • the preforms of the outer shell of the A pillar 11a1 and 11a2 overlap on both sides the preform of the outer shell of the roof frame 12a.
  • the preform 12a is in contact on its outside with the preform 11a1 of the A-pillar 11 and on its inside with the preform 11a2 of the outer shell and the A-pillar 11 in contact.
  • the contact area in a two-sided, undercut connection is twice as large compared to a single-ended connection.
  • the preforms 11i1 and 11i2 of the inner shell of the A-pillar 1 1 comprise the preform 12i of the inner shell of the roof frame on both sides.
  • the inner preform 11i2 of the A pillar 11 is longer and overlaps the inner preform 12i of the roof frame 12 over a longer portion than the inner preform 11i1.
  • the preforms of the A-pillar 11 need not surround the preforms of the roof frame 12 symmetrically, but may have on one side a larger contact surface than on the other side, such as this is illustrated by way of example and representatively in FIG. 3 by the preforms and 1 1 i2.
  • the danger of a weak point in the overlapping or connecting portion can be significantly reduced.
  • the geometric stiffness jump is reduced significantly at such a junction.
