Definitions
- the invention relates to a fiber fabric in which
- Fibers are embedded in a matrix.
- Fiber reinforced plastics are distinguished compared to metal ⁇ metallic structural materials by a significantly explicat- res specific gravity and higher specific properties.
- Fiber composite plastics for example, from
- a composite fiber plastic is a multiphase or mixed material of at least two main components, a bedding matrix and reinforcing fibers.
- a resin as a fiber, for example, a glass, carbon ⁇ material and / or aramid fiber used.
- FRP components are used in traditional static constructions and increasingly also in dynamically loaded components or components, such as in turbine components for Energyzeu ⁇ supply, including wind turbines, components for (rail) vehicles, components of electrical equipment (transformers, generators, motors) or in photovoltaics.
- a fiber is impregnated or infiltrated with the resin.
- the fibers typically carry at least partially a coating, such as a so-called ⁇ sizing on the surface, on the one hand a smooth fiber surface area for the weaving steps ensures on the other hand produces a compatibilization with the matrix.
- sizing consists of wet-chemical silane, ester acrylate or epoxy resin compounds and others.
- the object of the present invention is therefore to provide an FRP which has improved mechanical properties compared to the prior art.
- the present invention is a fiber composite plastic comprising fibers and a bedding matrix, wherein the surface of the fiber is activated by chemical and / or physical ⁇ cal means so that it reacts upon contact with the bedding matrix with this and so chemical
- the invention provides a process for producing a fiber composite plastic, wherein the upper surface of the fiber ⁇ is physically and / or chemically activated immediately before embedding in the matrix.
- Covalent single or multiple bonds are referred to as chemical bonds.
- Polar or ionic bonds and hydrogen bonds refer to physical, secondary valence bonds.
- fiber all types of fibers, in particular high-performance fibers can be used, for example, selected from the group of the following fibers: carbon fibers, glass fiber, aramid fiber, polymeric fibers such as polyethylene fiber, polypropylene fiber, polystyrene fiber, polyethylene terephthalate fiber, ceramic fiber such as silicon carbide fiber, alumina fibers or other reinforcing fibers.
- the fibers may be in the form of a woven, knitted, scrim, braid, non-woven fabric.
- thermoplastics such as epoxy resins, unsaturated polyester (UP) resins, vinyl ester (VE) resins, thermosets, thermosets and / or synthetic resins.
- resins can contain all types of fillers, according to a preferred embodiment, nanoscale particles are incorporated into the bedding matrix, for example the resin.
- the fibers are coated, so that, for example, wet-chemically a size has been applied to the fiber and encapsulates it.
- the size is for example of silane or epoxy ⁇ materials. Further examples are acrylates and polyurethane Esterverbindun ⁇ gene as well as the entire area of the polymeric resin systems that can be applied as a solution or in a dispersion to the fibers.
- the Akti ⁇ vation referred by introducing into a plasma, example ⁇ as introduction into a low-pressure or atmospheric-pressure plasma.
- corona systems are also suitable for physical surface activation.
- chemical and / or physical activation of the surface of, for example, coated fiber this is put into a reactive state, so brought to an energetic mountain, so that it reacts with everything, with which it comes into contact, and thus into an energy valley falls.
- the contacting with the bedding matrix accordingly preferably follows directly on the activation so that it is reacted with this matrix and not with the surrounding gases or moisture.
- the fiber composite plastic is prepared so that the surface of the fiber is physically and / or chemically activated immediately before embedding in the matrix.
- the physical activation by means of plasma also allows a thin organic or inorganic film to be deposited from the plasma, which then forms the reactive fiber surface, which is also referred to as plasma coating.
- the vibration load capacity under fluctuating or changing loads can be increased under tensile, bending and shear loads.
- the figure shows the diagram of a reference glass fiber with epoxy resin in comparison with the flame-silanized and a plasma-activated surface of the glass fiber.
- the reference had a strength of 12.42 MPa.
- This Fes ⁇ ACTION could be increased by 50% by a so-called Pyrosil compiler, that is the deposition of a wetting improving silicate layer, therefore also called Flammsilanmaschine, by 25% and replaced with 100 seconds in plasma by 33% and 30 seconds in the plasma
- the invention shows for the first time which increases in strength can be achieved by improving the adhesion between the fiber and the bedding matrix in FVks.
- the invention relates to a fiber sheet, embedded in which Fa ⁇ fibers in a matrix. According to the invention an increased mechanical strength is achieved by IMPROVE ⁇ tion of adhesion between the fiber and the matrix.
- interlaminar shear strength also called gap strength, or Transverse Fiber Bundle Test (TFBT).
- TFBT Transverse Fiber Bundle Test
