Definitions
- the present invention relates to a method for producing semi-finished fiber composites by means of circular braiding technology according to the preamble of claim 1.
- a semi-finished fiber composite manufactured according to the invention is specified in claim 10.
- the known methods have the disadvantage that the braiding fibers are damaged and weakened by the shear forces acting on them during the braiding or by friction at corresponding crossover points, which is the case, for example, with a braiding machine with two braiding rings that perform periodic lifting movements (DE-C- 101 15 935) can be reduced.
- the problem of fiber waviness continues to exist even with this arrangement.
- the present invention is therefore based on the object of creating a method for producing braided fiber composite semifinished products, in which the fiber damage is reduced and such semifinished products can be produced with significantly reduced waviness and improved material properties.
- the invention is based on the round braiding technique, in which a braiding core is braided with braiding threads, which are unwound via bobbins concentrically rotating around the braiding core, and is characterized in that the bobbins of a circulation notch with reinforcing threads and the bobbins of the opposite circulation at least are partially equipped with support threads, the support threads at least partially consisting of thermoplastic threads.
- thermoplastic threads which are known to be made of plastics (polyamides, polystyrenes, polyethylenes, polyesters etc.) and which melt when heated above the softening point, can be thermoformed and solidify again after cooling and also have good sliding properties, the friction of the braiding threads crossing each other during braiding are reduced, since the reinforcing threads slide on the thermoplastic threads with reduced friction. This results in a significant reduction in fiber damage and consequently an improvement in the material properties of the braid.
- the support threads which at least partially consist of thermoplastic threads, expediently hold the reinforcement threads deposited on the fiber core in position, so that at the same time the flexibility of the braiding process with regard to the braid core geometry is ensured.
- the elastic thermoplastic threads nestle so closely between the reinforcing threads that they come to lie parallel with practically no space and are therefore deposited almost without any waves.
- the associated reduced fiber waviness allows the positive properties of the reinforcing threads to be optimally utilized, so that the material properties of semi-finished fiber composite products produced according to the invention are greatly improved.
- the braided core is expediently braided several times in succession, in each case unidirectional reinforcing fiber individual layers being deposited on the braided core.
- the term "unidirectional" expresses that the layers are flat, not wavy. This in turn has the advantage that the predictability of the fiber structure of braids produced according to the invention is improved since the mathematical models can be used for unidirectional scrims the thickness of such individual layers is reduced to approximately half compared to a braid produced using conventional braiding technology, ie all bobbins are covered with reinforcing threads.
- Another advantage is that if the braid core is layered in layers before another individual layer is deposited, the previously deposited individual layer can be fixed by melting the thermoplastic threads. This prevents slipping or shifting in a simple and effective manner.
- the melting can be done, for example, by local. Warming or by applying a vacuum hose with subsequent heating. In the latter method, the deposited individual layer is compressed accordingly, which further reduces the waviness of the braid.
- An asymmetrical clapper is expediently possible, in which the number of clappers rotating in one direction is not equal to the number of clappers rotating in the opposite direction, which ensures a high degree of variation.
- the reinforcing threads consist of carbon, glass, Armid and / or Kevlar fibers, which are characterized by high tensile and compressive rigidity and high tensile and compressive strength.
- the support threads dissolve completely or at least partially at temperatures at which the braid is usually infiltrated.
- the support threads consist entirely or at least partially of Grilon threads or other thermoplastic threads with melting temperatures in the range of the infiltration temperature.
- the support threads can also consist of materials that are only partially melting.
- thermoplastic threads can be used that have a melting point that is above the typical infiltration temperature (e.g. polyester threads).
- Support threads of this type do not dissolve in the matrix system of the infiltrated braid, so that a targeted introduction of support threads is possible, which can be advantageous for some applications.
- each individual layer being braided at least partially has support threads consisting of thermoplastic threads. It is advantageous here that suitable requirements can be met in a simple manner to suit special requirements, so that the supporting threads in the infiltrated mesh are either completely, partially or not at all resolved.
- Figure 1 is a schematic representation of the thread guide on the braid core in side view.
- Fig. 2 is a schematic representation of the thread guide on the braid core in front view
- 3 shows a schematic configuration of the braiding machine for the laying down of reinforcing threads and supporting threads in a ratio of 3: 1.
- bobbins i.e. Bobbin holders, which take up braiding thread bobbins, are moved relative to one another on guideways, so that braid-forming thread crossovers occur.
- the guideways are two opposing concentric circular paths around a braid core to be braided. In this way it is achieved that the braiding threads of the bobbins cross in the positive direction of rotation with those of the negative direction of rotation, so that a braid is formed when braiding a three-dimensional braid core.
- Fig. 1 shows a simplified representation in side view of the thread guide in the inventive method.
- the braiding core 1 is moved in a known manner, for example with a robot (not shown) relative to the stationary braiding machine body 2 in the direction of the arrow 3 moves, the braiding threads 4a, 4b unwinding from the bobbins 5a and 5b and, after a deflection on the braiding ring 6, are deposited on the braiding core 1 via a corresponding crossover at the braiding points.
- the clappers 5a and 5b have different directions of rotation around the fiber core 1. For the sake of simplifying the drawing, only two of the many other braided threads 4a, 4b and bobbins 5a, 5b are shown in FIG. 1.
- the clappers 5a are equipped with reinforcing threads 4a made of carbon, glass, Armid and / or Kevlar fibers, and the clappers 5b rotating in the opposite direction are included
- Support threads 4b which at least partially consist of thermoplastic threads (e.g. Grilon or polyester threads).
- thermoplastic threads e.g. Grilon or polyester threads.
- the reinforcing threads 4a are shown in solid lines in FIG. 1, and the supporting threads 4b are shown in broken lines. Due to the good sliding properties of the thermoplastic threads, the friction during the deflection on the braided ring 6 and at the crossing points of the reinforcing threads 4a and the supporting threads 4b is reduced, which results in a significant decrease in the fiber damage.
- the reinforcing threads 4a are deposited without waves, being held in position by the supporting threads 4b, so that the flexibility of the braiding process with regard to the core geometry is the same as in conventional ones
- the braided core 1 is repeatedly in succession, by correspondingly moving the braided core 1 in Direction of the movement arrow 3, braided, with unidirectional individual layers being deposited in each case.
- the braiding process can also take place in only one direction of movement, with a renewed approach of
- Braided threads can be avoided, for example, by pulling the braided threads in the longitudinal direction of the braided core 1.
- the previously deposited individual layer can be pre-fixed before melting another individual layer by melting the braided thermoplastic threads. This can be done either by local heating or by applying a vacuum hose with subsequent heating. The latter has the advantage that the ripple is further reduced.
- Fig. 2 shows schematically the thread guide on the braid core 1 in front view with an asymmetrical assignment of the bobbin.
- the clappers are not shown in Fig. 2 for reasons of clarity.
- three quarters of the bobbins run counterclockwise around the braided core 1 and are covered with reinforcing threads 4a.
- the remaining bobbins, which run clockwise around the braid core 1, are covered with support threads 4b (shown in broken lines).
- support threads 4b shown in broken lines.
- FIG. 3 shows the placement of the braiding machine for depositing reinforcing threads and support threads in a ratio of 3: 1 in a schematic manner
- FIG. 3 shows the position of the clapper after a quarter Rotation.
- the rectangles marked in gray stand for bobbins that run counterclockwise around the braid core.
- the rectangles with the crosses represent bobbins that run clockwise, and the white rectangles represent empty spaces.
- Braided semi-finished fiber composite products according to the invention consequently consist of a multiplicity of unidirectional individual layers deposited in layers, each individual layer having braided support threads which at least partially consist of thermoplastic threads.
- support threads which have a melting temperature of approx. 85 ° C, they dissolve when the mesh is infiltrated in the matrix system.
- polyester threads are used that have a melting point above 180 ° C, they remain undissolved in the infiltrated braid.
- support threads or support thread compositions can be used which only partially dissolve when the braid is infiltrated.
