Definitions
- the invention relates to a method for producing a textile semifinished product for a textile fiber composite structure, which consists essentially of Roving Published Product, the Roving revealede are stored depending on final product at a defined position and overlap, and a semi-finished textile.
- fiber composites offer
- the principle is that in particular high-strength and stiff fibers are embedded in a matrix in a load-compatible manner, resulting in components with outstanding mechanical properties which are typically 25% lighter than aluminum and 50% lighter than comparable steel structures
- preforms In order to produce fiber composite structures with fibers arranged according to the force flow, so-called preforms have been produced as textile semi-finished products for selected applications. These are usually two- or three-dimensional structures with load-oriented fiber alignment.
- these textile structures are cut to size separately and assembled in a subsequent process into thicker packages, before they are formed into a finished composite component, for example by means of a resin injection process.
- Roving pieces on the three-dimensional shape surface is made so that the same placed and fixed in predefined positions.
- a thermally activated binder it has proven to be advantageous to attach a heater to the laying head and to heat the sliver during transport to the storage location, whereby the binder is activated.
- Tool for the shaping of plastic material webs can serve, the heater is integrated to fix the spatial shape in the tool.
- Laying equipment is not only very expensive due to its complexity, but also expensive to program and extremely limited in productivity. It is therefore particularly suitable for complicated structures and small quantities. For larger numbers and larger areas can not be used on such a device.
- This shift can be achieved by stretching the
- Carrier material in the longitudinal direction of Roving Korean, but also by a
- the attachment of Roving Koreane with its one end on the substrate can be done in different ways.
- the carrier material itself has adhesive properties which are already sufficient to fix the roving pieces in such a way that the compound does not dissolve in the later draping and also in the resin impregnation process.
- These adhesive properties of the surface of the carrier material can be achieved in particular by thermal activation of a binder.
- this adhesive equipment may also be punctiform to ensure the flexibility of this connection required for the later draping process.
- the adhesive material of the carrier material or the Roving is generated, whereby a nearly free mobility during draping is ensured.
- the term "row" of roving pieces contained in the claims is not limited to a straight-line juxtaposition of roving pieces, but includes almost any other graduations, as exemplified in the exemplary embodiments.
- the invention is not limited to the use of roving pieces of the same length Depending on the desired layer thickness or the number of overlapping rovings in the section, the length of the rovings can be selected accordingly result in long rovings at the same wide fixing zone a greater number of overlaps than shorter rovings.
- modified surface shape or size are converted and each case after
- Deformation direction with respect to the orientation of the rovings of the subsequent power flow direction can be adjusted.
- FIG. 1 shows a section of the carrier material with a row of roving pieces
- FIG. 2 shows a carrier material with a stepped arrangement of roving pieces
- FIG. 3 shows an arrangement of roving pieces with end-side spread
- FIG. 4 shows a roof-tile-like arrangement of a plurality of rows of rovings
- FIG. 6 shows an arrangement of several rows of rovings in one
- FIG. 1 shows a web-shaped carrier material 1 in the form of a carrier web section, on which roving pieces 2 are arranged in a first row, which have a fixing region 3, in which they are connected to the carrier material 1.
- the roving pieces 2 have adhesive properties limited to the fixing region 3.
- the web-shaped carrier material 1 itself could have adhesive properties. Accordingly, in the present example, the roving pieces 2 would then be connected over the whole area with the web-shaped carrier material 1. If this were not desired, which would anyway only be limited to the first row, the web-shaped carrier material could be separated below the fixing regions 3 or would have no adhesive properties in this end region. More rows of
- Roving pieces 2 would continue to build over the row shown here and then overlap correspondingly the roving pieces 2 of the first row, as shown for example in Figures 4 and 5.
- Whether and by what amount the roving pieces are spaced apart within each row depends on the later desired properties. However, it is advantageous not to equip the carrier with the adhesive properties in the case of the spacing, since in this case also overlying roving rows could stick to the carrier material.
- FIG. 2 demonstrates that the arrangement of roving pieces 4 on the web-shaped carrier material 6 can also be alternating. 5 with fixing points are given here, which consist of a point-shaped adhesive arrangement on the substrate 1 or the
- Roving pieces 4 may exist or may be formed, for example, in the context of the invention by a stapling.
- FIG. 3 shows an arrangement, corresponding essentially to FIG. 2, of roving pieces 7, which are additionally spread apart in their end region 8. This spreading has the advantage that the grades of the ends of the Roving Swisse 7 are not visible in the final product.
- the Fixing the Roving sensiblee 7 takes place here by means of two fixing points. This fixation allows for the subsequent shaping a significant mobility of Roving stainede 7 on the substrate.
- FIG. 4 shows a plurality of rows 10a to 10e of roving pieces which overlap like a roof tile.
- the roving pieces 11a to 11h in FIG. 5 overlap significantly more than the roving pieces 10a to 10e in FIG. 4 because of their length. It is assumed in each case that the end regions of the rovings with which they are fixed on the carrier material are about the same dimension.
- FIGS. 4 and 5 The illustration in FIGS. 4 and 5 is intended to make it clear that textile semi-finished products can be produced by the construction according to the invention in one go, which differ considerably in their thickness from one another due to the layering.
- the roving pieces 12a to 12e are in the form of a
- Circular segment arranged. This is intended to demonstrate that the invention is not limited to the arrangement of Roving Korean #2n which extend straight across the web-shaped carrier material, not shown here. Rather, any other arrangements of Roving Korean #2n could be formed here.
- the covering of the web-shaped carrier material with a binder can be carried out analogously to DE 10 2007 012 609 A1. Likewise, there are no requirements beyond the state of the art for the preparation and implementation of the subsequent resin infusion process.
