Definitions

  • the present invention relates to a process for the production of fiber-reinforced composite materials.
  • Fabric-reinforced fiber composite materials are often produced by the RTM process (resin-transfer-molding) or the RIM process (reaction-injection-molding).
  • tissue or textile structures are tightly packed in a tool and fixed.
  • a resin-hardener mixture resin system
  • WO 2009/077616 discloses a method for producing a molded part by impregnating a carrier material with foamable reactive resins (PU, epoxy or UP resin) and subsequent foaming and curing of the resin.
  • foamable reactive resins PU, epoxy or UP resin
  • a fundamental problem is that a reaction resin has to penetrate tightly packed fiber structures. This often succeeds only with great effort, for example by very high pressures, application of vacuum, special low-viscosity formulations or by short-term opening and re-closing of the tool.
  • the resin system also does not flow evenly through the fiber-filled tool. There are more or less unfilled places. There are often trapped air that could not displace the resin system.
  • the injection can also lead to shifts in the textile structures, which leads to poorer mechanical properties of the component.
  • the time required for injection prolongs the tool life and reduces throughput.
  • casting machines with low-pressure or high-pressure pumps for conveying the resin and hardener components are inserted into the tool via a mixing chamber.
  • very expensive processing machines with high pressure pumps have to be used.
  • remedy could be achieved by two-dimensional introduction of the reaction resin by means of a carrier.
  • the carrier can be, for example, a fabric (prepreg), fleece or open-cell foam.
  • open-celled refers to a foam structure defined by each cell having at least two pores or destroyed surfaces. In addition, the majority of cell fins must belong to at least three cells. Closed-cell foams are generally produced on the basis of polyurethane (PU), polyvinyl chloride (PVC), polymethacrylimide (PMI) and polystyrene (PS) (see Arnim Kraatz, Dissertation 2007, University of Halle).
  • PU polyurethane
  • PVC polyvinyl chloride
  • PMI polymethacrylimide
  • PS polystyrene
  • the subject matter of the present invention is thus a process for producing composite materials, comprising the following steps: (i) impregnating a support (T) with at least one reactive resin (H), (ii) introducing the impregnated with at least one reactive resin Carrier in a tool (W), (iii) introducing at least one fiber-containing body (K) into the tool (W), (iv) curing the at least one reactive resin in the tool, wherein the carrier (T) is an open cell foam based on of melamine resin.
  • the bodies (K) containing fibers are partly inserted before the introduction of the resin-impregnated carrier into the tool.
  • further fibers containing body (K) textile structures
  • the resin-impregnated carrier (T) is thus located between the textile structures.
  • the fiber-containing body (K) of textile structure is preferred.
  • tool is meant two or more divided shapes of steel, aluminum or mineral reinforced plastic.
  • the molds are divided into two parts (upper and lower shell) and installed in a press.
  • the occurring compression pressures are usually between 5 and 20 bar.
  • the tools are designed for larger, flat parts.
  • the usual processing temperatures of the reaction resins are between 25 ° C and 90 ° C, the mold temperatures are usually between 40 ° C and 120 ° C.
  • the carrier is absorbent.
  • the term "absorbent" means that the reaction resin used can be absorbed in the required amounts, which depend on the part geometries and the proportion of fiber, without dripping off in the process according to the invention for producing glass or carbon fiber reinforced composite materials a resin is incorporated in a carrier, preferably in an absorbent carrier.
  • the carrier used is an open-cell foam based on melamine resin (for example Basotect® from BASF SE).
  • Basotect® is an open-cell melamine / formaldehyde foam of very low density and low flammability and is very absorbent.
  • step (ii) is carried out before step (iii).
  • step (iii) is carried out before step (ii). In a further embodiment of the method according to the invention, step (iii) is carried out in each case before and after step (ii).
  • steps (ii) and (iii) are carried out simultaneously.
  • the reactive resin (H) is selected from the group comprising polyurethane resins, polyester resins, epoxy resins, phenolic resins, melamine resins, urea resins, furan resins, silicone resins, vinyl resins and cast polyamide (activated caprolactam). Suitable resins are described in Kunststoffhandbuch Volume 10, Duoplastics by Becker and Braun, Hanser Verlag.
  • the reactive resin is selected from the group consisting of polyurethane resins, polyester resins, epoxy resins and activated caprolactam.
  • the fiber-containing body (K) is selected from fiberglass and carbon fiber mats.
  • the process according to the invention can be carried out continuously.
  • a carrier preferably an absorbent carrier, particularly preferably an open-cell foam, such as Basotect®
  • a resin system eg polyurethane, polyester, epoxy or activated caprolactam (cast nylon)
  • the liquid resin systems then do not need to be injected or potted into the tissue-filled tool, but can be incorporated into the tool by placing the resin impregnated foam into the mold. Closing the heated tool and compacting destroys the structure of the open cell foam, dispersing the resin system in the mold and soaking the fiber material.
  • the remaining foam parts reinforce the structure of the component in a preferred embodiment and preferably, because they are non-combustible, contribute to flame retardancy.
  • the impregnation of the support material can take place at a lower temperature than in the tool, thereby increasing the pot life of the resin system and very reactive systems can be used.
  • very reactive systems In the "classical" RTM process only low-viscosity components can be used, in the proposed method, higher-viscosity resins, hardeners or additives can be used, since the required flow path of the resin system in the component is limited to a few millimeters Structures are excluded by the proposed method because no liquid resins are forced through the fibers at high pressure.
  • a further subject of the present invention is also a composite material which can be produced by the process according to the invention.
  • Another object of the present invention is also the use of a producible by the process according to the invention composite material for the production of composite components for use in transportation, for example in the automotive industry.
  • a 4 mm thick foam mat made of Basotect ® was evenly impregnated with epoxy resin using a squeegee.
  • the resin absorption was about 2 kg / m 2 foam mat.
