Definitions
- the invention relates to a method for producing a structural hollow component made of fiber-reinforced plastic according to the preamble of claim 1.
- At least one layer of e.g. uni- or bidirectionally directed reinforcing fibers placed between the upper and lower tool of a heated press and impregnated the fiber layer with a thermosetting plastic, such as an epoxy resin with hardener, which is injected under pressure into the cavity with the fiber layer between the upper and lower tool.
- a thermosetting plastic such as an epoxy resin with hardener
- the vacuum injection process is used in which a vacuum is applied instead of pressure to suck the thermosetting plastic into the fiber layer.
- WO 02/072328 A1 discloses a support core for producing structural hollow components made of plastic, which contains polyvinylpyrrolinone (PVP) as the water-soluble binder.
- PVP polyvinylpyrrolinone
- a braiding system can be used, wherein the support core is in the eye of the braiding system, while the reinforcing threads are removed under high voltage from the periphery.
- the support core according to WO 02/072328 A1 has too low a breaking strength in order to withstand these high pull-off forces.
- the object of the invention is therefore to provide a water-dispersible support core for an RTM process for the production of structural hollow components made of fiber-reinforced plastic, which reliably withstands the high withdrawal forces during wrapping with the reinforcing fibers.
- the support core used according to the invention is characterized in that the water-soluble binder at least partially contains a silicate.
- a water glass is used as the binder.
- the binder is characterized in that the SiO 2 / M 2 O weight ratio is preferably in the range from 1.6 to 4.0, in particular from 1.8 to 3.5, where M is sodium and / or potassium and / or or lithium ions.
- the binder preferably has a solids content of SiO 2 and M 2 O in the range of 30 to 60 wt .-% to.
- the support core has a relatively small proportion of binder of preferably 0.5 to 8, in particular 1 to 5 wt .-% and thus a correspondingly high proportion of filler.
- binder preferably 0.5 to 8, in particular 1 to 5 wt .-% and thus a correspondingly high proportion of filler.
- Carbon fibers are preferably used as reinforcing fibers. However, other reinforcing fibers may be used, for example glass fibers.
- the packaging is preferably with a braiding performed as used for braiding cables and ropes, wherein the support core occupies the place of the cable core in the eye of the plant.
- the production of the fiber-reinforced structural hollow component is then preferably carried out by the RTM process. That is, the prefabricated support core is placed between the two tools, so for example the upper and the lower tool of a heated press, whereupon the reinforcing fibers are impregnated on the support core with a thermosetting plastic, such as an epoxy resin in the cavity with the support core between the two tool parts is injected.
- a thermosetting plastic such as an epoxy resin in the cavity with the support core between the two tool parts is injected.
- the Re- sign Transfer Molding (RTM) method can be carried out, in which the thermosetting plastic is pressed under a pressure of 10 bar and more in the cavity, or the vacuum injection method in which the thermosetting plastic in the Cavity is sucked. After curing of the resin is removed from the mold and the support core flushed with water, so that the fiber-reinforced structural hollow component is formed.
- the water glass used may be, for example, a soda water glass. However, other water glasses can be used, in particular potassium water glass or lithium water glass.
- the binder may contain other alkali metal compounds which may be added in solid form or as an aqueous solution, for example sodium or potassium hydroxide or in dissolved form sodium or potassium hydroxide solution.
- the modulus (SiO 2 / M 2 O ratio) and the solids content can be controlled.
- the filler consists of a water-insoluble particulate material, preferably at least partially of sand.
- the sand preferably has an average particle size of 100 to 500 ⁇ m.
- the support cores for the method according to the invention are preferably produced with a core shooter, as described, for example, in DE 102 00 927 A1 for the production of cores for foundry purposes.
- a core shooter as described, for example, in DE 102 00 927 A1 for the production of cores for foundry purposes.
- the sand content of the filler be at least 30% by weight. % is.
- the filler preferably contains plastic particles, usually with a mean particle size of 100 microns to 2 mm.
- the plastic particles are preferably formed from shredded plastic waste. So that the particles are more spherical, plastic granules are preferably used. Due to the spherical shape, the mentioned fluidity of the mixture of filler, dissolved binder and water is increased accordingly.
- the plastic particles also increase the elasticity of the nozzle core, thus reducing its sputters.
- the weight of the support cores can be significantly reduced by the use of plastic particles as a filler.
- the proportion of the plastic in the filler is preferably at least 10% by weight. However, it can also be significantly higher and 50 wt .-% and more. This allows much lighter and therefore better manageable cores can be obtained.
- a weight reduction of the cores is also achievable with ceramic particles or glass bubbles.
- the ceramic particles may be formed, for example, by fly ash. Since the fly ash particles are also rather spherical in shape, they also ensure the fluidity required for emptying. Of course, this is even more true for hollow glass spheres as filler.
- the average particle size of the ceramic particles and the glass bubbles may be, for example, 50 to 800 ⁇ m.
- the water content of the molding material ie the mixture of filler, binder and water, is preferably from 0.2 to 5 wt .-%, based on the weight of the filler. This ensures the processability of the molding material when it is introduced into the mold, for example by enclosing or pressing in. However, the water content is chosen as low as possible, since the nozzle core must be dried before removal from the mold so that it has the required strength.
- a preferred molding material consists for example of 0.5 to 5 wt .-%, in particular 1 to 2 wt .-% silicate-containing water-soluble binder, with a SiO 2 / M 2 O ratio preferably in the range of 1.6 to 4, 0, where M Sodium and / or potassium and / or lithium ions, and a solids content of 30 to 60%; and rest sand.
- any structural hollow components made of fiber-reinforced plastic can be produced by the method according to the invention.
- the support columns ie the A-, B- and C-pillar, sills and bumpers are to be mentioned as examples of such fiber-reinforced structural hollow components.
